Suggested March 2024 What Is A Vpn And What Is It Used For?

A VPN, or Virtual Private Network is an extremely useful tool for every internet user, no matter how much time you spend online or what sort of stuff you do on the internet. A VPN gives you more security and privacy when you go online – things that are hard to come by in today’s information age.

What Is a VPN and How Does It Work?

If you have a general idea of how the internet works, you probably know that your internet service provider (ISP) and some other organizations have ways of tracking your online activity. Your browser’s private browsing mode can’t help protect your data and give you peace of mind, while a VPN can do more than that.

VPN is a technology that protects your online activity by adding an extra level of encryption to your data. It connects your computer or a smartphone to a private network, allowing your data to go through an encrypted “tunnel”.

It travels from your device to some other point on the internet, often in another country, before making its way to the public internet. Your data stays hidden the entire time. All an ISP can see is that you’re connected to a private network. 

When you connect your device to a VPN, it behaves as if it was on the same local network as the VPN. It allows you to access local network resources even if physically you’re accessing the internet from a different country. You can also browse the internet as if you were based at the VPN’s location. For example, if you’re using a USA-based VPN from outside the US, the websites will see your online activity as if it was coming from within the country. 

What IS a VPN Used For?

Some people associate using a VPN with the need to hide your online activity. In reality, a VPN comes with a number of benefits that can help any internet user in their everyday life. Here are a few reasons why you might want to start using a VPN.

Secure Your Connection When Using Public WiFi

When you’re browsing the internet at home, your connection is via a password-protected router and a private WiFi network. However, when you connect to a public WiFi network – whether it’s at a coffee shop, a hotel, or an airport – your traffic isn’t protected anymore. Those networks offer open access to all users, which makes it much easier to intercept the wireless network traffic. 

That’s why it’s a good idea to use a VPN next time you decide to connect to a public WiFi network to send an email or check your Instagram account. 

Take Back Your Online Privacy

Using a VPN is one of the simplest and most effective ways to gain back your online privacy and stop others from collecting your data.

Access Geo-Blocked Content 

One of the most popular reasons for getting a VPN service is to access geo-blocked websites. Sometimes you’ll find that certain content, streaming services, or websites are blocked or have restricted access based on your location. Using a VPN is the easiest way to bypass those restrictions. 

This can be useful if you ever find that certain movies or TV shows aren’t available on your streaming platform in your region. Connecting to a VPN server from the appropriate country can easily fix that. 

When traveling, you might find yourself in a country where entire websites and services are geo-blocked. For instance, if you want to access LinkedIn in Russia, you’ll have to use a VPN or other means of getting around geo-restrictions. 

Bypass Your School or Workplace Firewall

When using the internet at your school or workplace, you’re bound to come across blocked websites that management doesn’t want you to access. They do this by using firewalls that filter all web content and keep you away from the blacklisted sites. 

There’s a number of workarounds that can help you bypass your school or workplace firewall. One of the easiest ways to do it is via the VPN service. When you connect to a VPN and start browsing, all the internet traffic is encrypted, and the firewall can’t see what you’re doing and what sites you’re visiting on the network connection. This way you can view the sites you want no matter the time and place.

Save Money on Shopping

Aside from the obvious benefits you get from using a VPN, you can get some extra perks if you think outside the box. A VPN can help you save money on shopping. Admittedly, it does require some time and effort.

You can use a VPN to connect to different servers across the world and find the cheapest prices. The things you can save money on include streaming services, software subscription plans, flight tickets, and even hotels. In theory, you can find cheaper prices for everything. However, don’t forget that some of the price differences will be covered by exchange rates and bank fees. 

Do You Need a VPN?

While VPNs come with many benefits, they’re not flawless. The biggest downside of using a VPN is a connection speed drop. Since you’re sending your data to another location before it reaches the right server, your VPN connection speed is bound to be slower than your regular internet speed. 

However, if that’s not a big problem for you, or if the connection speed drop isn’t significant, using a VPN is definitely a good idea. All that’s left is to choose the right VPN service for you. Luckily, there are plenty of options out there – from a Windows built-in option, VPN Chrome extensions, best free options for Mac, and the best VPN apps out there.

Digital (Web) Psychology – What Is It And How Can It Be Used?

Simon Swan’s interview with Andrew Nicholson, Founder of the-Guku showing how behavioural economics influences customer online purchases and growing demand for Data?

Andrew is the founder of the-Guku, a digital marketing consultancy specialising in behavioural economics and the relationship this plays in influencing customers through their online purchase patterns.

Guku combine #DigitalMarketing, #BehavioralEconomics & #Psychology know-how to understand your customers better than they understand themselves!

In my interview with Andrew, he lifts the lid on the growing demand for data on behavioural economics,  real-life examples of companies already successfully using these techniques and Andrew’s personal journey of  launching his very own consultancy…

Q. You seem to have uncovered an interesting niche in web psychology, can you summarise what this is all about?

Absolutely.  As I progressed through my MSc, it became clear that there was a huge understanding of marketing technology, but a relative dearth of knowledge in how that technology related to people’s behaviour (with the exception of UX).  I was fortunately able to subvert my studies to pursue a Digital Psychology agenda – and I was able to spend my final year focussing exclusively on this exciting new discipline.

I’ve always been fascinated by people – it’s the reason why I got into marketing in the first place, but I’ve always felt that digital marketing spends far too much time looking at what customers do, and not enough time trying to understand why they do it.  Google Analytics is the perfect example – there’s so much data available – bounce rates, conversion rates, basket abandonment rates etc. but none of it gives you an answer to why your customers are (or aren’t!) buying your product online.

Digital Psychology (also known as web psychology) takes a different approach.  It looks at online behaviour through the lens of psychology and behavioral economics – and through this lens, explains why customers are acting the way they are.  Better still, by applying the lessons learnt from social science theory, we’re able to remove barriers to online conversion, and increase customer spend and retention.

The metaphor I like to use that best describes this approach is of a fisherman standing in waders in a river. The river represents technology – always changing, always moving, often so fast we struggle to keep up.  The one constant in this scene is the fisherman, representing the human brain.  As fast as technology may change, the human brain remains the same, and has done so for hundreds of thousands of years.  If we start viewing technology through a neurological perspective, rather than trying to influence humanity from a technological perspective, we’re going to be on far firmer, and longer lasting, ground.

Q. Can you provide some good examples of companies using web psychology?

I’ve just published an article for econsultancy showing what I believe are the top ten best examples of digital psychology in action.  There’s no doubt that Amazon are the clear winners – they utilise pretty much every tactic from the Digital Psychology toolkit. From classic examples of anchoring, to scarcity, reciprocity and cognitive consistency – they even take digital psychology offline, with their approach to direct mail, which is something I’ve not seen any other pure play brands doing (yet).

Another incredibly powerful website, this time utilising social proof as their main conversion trigger, is chúng tôi I counted 5 separate social proof devices on one hotel profile alone. chúng tôi is currently ranked the 103rd most popular website in the world by Alexa, and has a bounce rate of just 24.8%.  That to me is remarkable!

What’s also really interesting is that there are also a number of big brands that should know better, but are doing things really badly. A lot of digital psychology theory is counter intuitive – people often do the opposite of what we instinctively expect, and brands need to understand that simply following the HiPPO (Highest Paid Person’s Opinion) is a recipe for disaster.

Let me use a classic behavioural economics example to illustrate this.  If you were to ask someone if there was a correlation between a roll of a dice, and their estimation of the percentage of African Countries in the UN, they would understandably tell you to stop being ridiculous.  Yet, behavioural economists, Tversky and Kahneman found, all the way back in 1974, that there was a direct and replicable link between an equally unrelated event (in this case, the spinning of a rigged real of fortune device), and a subject’s response to the aforementioned question.  In fact, subject’s answers varied by an average of 20%, depending on whether they scored a 10, or a 65, on the wheel of fortune.

This technique is known as anchoring – and it’s as powerful today as it was back in the 1970’s, and I have carried out numerous experiments confirming its influence in a digital setting.  I have yet to prove it, but I honestly believe that even a well placed telephone number could influence a customer’s average spend per transaction.  If there are any companies out there that would like to work with me to prove this hypothesis, do drop me a line!

Q.  Do you see web psychology playing a role in the digital marketing mix or should it be used more as a strategic vision piece?

Digital psychology isn’t a tactic in itself – it’s a way of thinking that can be applied across the digital marketing mix (and also traditional marketing approaches) at a strategic level.

From customer acquisition, through to user experience and retention, they are using digital psychology techniques such as social proof, effort, validation and reciprocity to increase sign up, stickiness, and ultimately conversion.  It’s a powerful combination, and I’ve no doubt the tool will be putting the larger MA providers to shame when it goes live next year.

The digital marketing mix, whilst encompassing a varied range of approaches, such as paid search, inbound, social, email etc. has one common theme – every tactic is aimed at influencing human behaviour (it can even be argued that as Google focuses its results more and more on UX, that the same can be said about SEO).

Why would you therefore go to all the effort and expense of building and managing your digital marketing tactics, without first trying to understand how they relate to human behaviour? It’s like I was saying before – digital marketers need to stop putting the technology first, and start understanding their customers better.

Q. You’ve recently made the move from working in-house to creating your own digital agency – what are the biggest learning curves you’ve encountered?

I’m not going to lie, it’s been challenging. The great thing about working in house is that you get to focus all your time on doing what you love.  I was a digital marketer, doing digital marketing, and I was as happy as a pig in muck – but the problem was that I wasn’t being challenged.

But when you start-up you own consultancy, suddenly there’s all this other stuff that you need to do – accounting, HR, business development etc. work suddenly starts to get a lot more complicated.  The flipside of this is of course that you’re doing it for yourself, and you’re learning daily, which is very exciting. I’ve also been able to focus my energies on developing digital psychology methodologies which I can use to bring value to my clients.

One of the steepest learning curves I’ve faced is learning to put a hard value on my time.  When you’re client side, you tend to add value through your company indiscriminately – if someone in another department or segment needs assistance, you’re free to give it as you know it’s for the greater good of the company.  When you’re working agency-side, every hour has to be logged and apportioned appropriately. It’s a very different discipline, and I’m still coming to terms with it.

Q5. What’s your thoughts on the next frontier/challenge for digital marketing?

What Is Spotify Duo, And Is It For You?

Music streaming services like Spotify offer fantastic value for the money, but what if a family plan is too big for you, and you don’t want to pay double the price of a single subscription? Spotify Duo may be precisely what you need if that sounds like you.

What Is Spotify Duo?

Spotify Duo is simply a subscription tier that provides a Spotify Premium account to two people at a lower cost than either two individual Premium subscriptions or the Premium Family Plan, which provides Spotify Premium for six people.

Table of Contents

Spotify Duo costs $12.99 a month. In contrast, a single subscription plan costs $9.99, and the Family Plan comes in at $14.99. So you save a lot compared to the $20 for both individual subscriptions. It’s only two dollars cheaper than the family plan, and you lose four subscription slots. However, if you only need Spotify for two people, there’s little reason to pay the extra two bucks.

One cool feature of Spotify Duo is that you can have a “Duo mix” shared playlist with the other person, similar to the “family mix” of the top-tier option.

There are terms and conditions for Spotify Duo. The subscription is meant for two people who live in the same household. So couples, roommates, or other pairs of people who live together at the same address are eligible. If you live at different addresses, you’re not supposed to use Spotify Duo.

Spotify Duo Eligibility in Detail

There are three main requirements that anyone who uses Spotify Duo must fulfill to be eligible.

The first is that both the “primary” account holder and the “subsidiary” account holder must reside at the same physical address.

The second requirement is that both account holders provide their home addresses. If the two addresses don’t match, you can’t use Duo.

You also have to agree to the possibility that you may be asked to verify your addresses again from time to time.

Spotify’s terms and conditions state that they reserve the right to suspend or cancel your Duo subscription if they believe you aren’t sticking to the rules.

The Perks of Spotify Premium

Whichever of the Premium subscription tiers you choose, you’re getting the same perks, but what are they? Why not just use Spotify’s free tier?

The free version of Spotify also doesn’t allow you to control which songs are being played. You get a limited number of skips, so this experience is more radio-like than the premium option and may not suit your musical tastes. 

Overall, we consider Spotify’s free tier too limited to be a primary music streaming service. For a more detailed evaluation of Spotify Premium, check out Is Spotify Premium Worth it?

When Is the Family Plan Better?

If you have more than two people who want Spotify Premium, the Family plan is by far the cheapest way to do it. Even if you only use three of the six slots, it’s still a better deal. Of course, the more people on your family plan, the cheaper it works out on a per-person basis. 

Spotify Account-sharing Enforcement

Of course, when using a family plan (or Duo), you may be tempted to split the cost with people who don’t live with you. If you do this, you violate the terms and conditions and risk getting your account suspended.

It’s unclear how exactly Spotify would detect and enforce these rules. In 2023, Spotify experimented with GPS-based validation, but this idea is no longer in effect now.

Just be aware that, in the future, you’ll have no recourse if Spotify does decide to enforce its policies.

Spotify Duo Alternatives

There are many other streaming services to choose from these days, but none of them offer a direct competitor to Duo at the time of writing. While services like Apple Music, Amazon Music, or YouTube Music offer single- and family- subscriptions, you won’t find two-person options.

Of course, if you’re already a Spotify user and simply want to add one person to your subscription, you already know that you’re happy with what the service offers. 

It’s only an issue when you’re deciding between different services before taking the plunge. There’s more to consider than just pure price. 

For example, YouTube Premium includes both ad-free YouTube and a music service.

Additionally, it’s essential to subscribe to the service that hosts the music you want to listen to. If your favorite artist isn’t on Spotify, you’ll have to go elsewhere. 

Is Spotify Premium Duo for You?

With all the relevant information on the table, it’s time to figure out if the Spotify Premium Duo plan is right for you instead of having separate accounts.

If you’re two people living at the same address who want Spotify Premium, put a tick in the “yes” column. If you’re happy with it, it’s a great deal.

One small caveat is that the primary account holder is responsible for the whole bill. So if you’re splitting the cost with someone, you’ll have to put up the cash and get it back from them. If you’re a secondary account user, just remember that the primary account holder has the power to kick you off. So be nice to them! 

What Is Duda Website Platform And Is It A Good Fit For Agencies?

There have never been more high quality choices for creating a web presence as there are today, which ultimately comes down to choosing a website platform that best serves your business needs. Duda focuses on the business needs of agencies that require the infrastructure to grow with more customers.

This article began with a WordPress versus Wix versus Duda angle.

But as I discussed each platform with the various stakeholders I came to realize that each platform did what they did really well serving, to a certain extent, a different user base.

Thus, this article became a three-part series exploring three different publishing platforms (Duda, WordPress and Wix) to understand what makes them the best in their chosen market.

Each platform is the best at what they do and today we look at why Duda is popular with web design and SEO agencies.

Choosing the Best Website Platform

Today there are two competing ways to create a web presence, proprietary (also known as closed source) and open source.

Proprietary content management systems take care of the technology underneath each website, freeing agencies and business owners to focus on growing their business.

Choosing a content management system (CMS) platform is not a matter of choosing the best CMS. It’s about choosing the platform that’s best for your business model.

The business case for closed source website building platforms like Duda or Wix is that they handle the technical aspects of building a website, allowing businesses to focus on their business without having to worry about updates, structured data, or optimizing for search engines.

Duda Professional Website Builder

Duda is a closed source platform designed to fulfill the needs of agencies and web professionals, regardless of size.

It offers collaboration and client management tools to help web professionals scale the process of launching and maintaining websites.

The focus on helping agencies scale is evident in the fact that Duda doesn’t charge customers extra for additional bandwidth or storage space.

What Duda excels at is making it easy and fast for agencies to prototype designs, collaborate with team members and clients and have all the features necessary for running a business on both the agency and the client side.

I asked Duda what makes Duda a good choice for agencies:

“The Duda platform is designed to help agencies build beautiful, modern websites for their clients faster than they ever thought possible at any scale.

No matter whether you have 10 or 10,000 clients, Duda provides agencies with an ultra-flexible platform that enables them to create conversion-driving websites with everything they need included–from hosting, templates, widgets, and SSL certificates all the way to our very knowledgeable support staff that is there to help agencies every step of the way.

Duda provides agencies with a user-friendly web design interface clients can access to update websites on their own.

And since the entire platform is white labeled, clients will only know you’re using Duda if you want them to.

Finally, Duda’s purpose is not only to be a leading website-building platform for agencies but also a valuable business partner for our agency customers, constantly seeking to support their business growth.

This vision guides us in everything we do as a company – from strategic business decisions to our product roadmap.”

Duda Scales Up for Growth

Wix’s model focuses on helping businesses easily build high performance websites and do business, with no technical knowledge necessary.

Duda’s approach is providing the white label technical infrastructure for agencies to build high performance websites for their clients, at scale.

Many SEO and web design agencies aspire to scale up to hundreds or even thousands of clients. Doing that demands a lot of technical infrastructure and human talent to take on the  prototyping, development and client collaboration at scale – all things that Duda provides.

I asked Duda how well they scale:

“Duda scales effectively.  In fact, Duda doesn’t charge its customers for storage or bandwidth, enabling them to scale without being concerned about incurring additional cost.

Duda’s platform is hosted on AWS. We guarantee 99.9% uptime and believe in transparency with regards to our uptime SLAs.

With Duda’s API, agencies can automate workflows to significantly increase efficiency and build client websites at scale.”

SEO is Baked into the Duda Platform

Performing well on search engines is critical.

As a closed source website building platform, Duda takes care of technical SEO factors as well as site speed performance, especially as measured by Google’s core web vitals metrics.

Core Web Vitals are performance metrics designed to measure how well a webpage performs for users.

A high core web vitals score will generally be matched with a better user experience, less visitor frustrations and higher conversion rates on sales.

Google’s support page about core web vitals shares why core web vitals track with higher sales and earnings:

“Studies show that better Core Web Vitals improves user engagement and business metrics. For example:

When a site meets the Core Web Vitals thresholds, research showed that users were 24% less likely to abandon page load.

With each 100ms reduction in Largest Contentful Paint (LCP), web conversion rate for Farfetch increased by 1.3%.

Reducing Cumulative Layout Shift (CLS) by 0.2 led Yahoo! JAPAN to a 15% increase in page views per session, 13% longer session durations, and a 1.72 percentage point decrease in bounce rate.

Reducing CLS from 1.65 to 0 significantly uplifted domain rankings globally for redBus.”

Clearly, a high core web vitals score is important for websites and in general those high scores are difficult to achieve, except for sites created on the Duda platform.

Duda has long been known as the Core Web Vitals champion, as reported by the independent HTTPArchive, a score derived from a sampling of website performance as experienced by real website visitors.

The current core web vitals scores on HTTPArchive shows Duda outperforming both WordPress and Wix by a wide margin.

Duda shared this about how SEO is native to the platform:

This makes it possible for agencies to offer websites to their clients with low/no maintenance load.

In addition, Duda provides agencies with a user-friendly web design interface clients can access to update websites on their own.

And since the entire platform is white labeled, clients will only know you’re using Duda if you want them to.

Finally, Duda’s purpose is not only to be a leading website-building platform for agencies but also a valuable business partner for our agency customers, constantly seeking to support their business growth.

This vision guides us in everything we do as a company – from strategic business decisions to our product roadmap.”

Why Agencies Choose Duda

There are over 20,000 agencies who rely on Duda to help build and manage client websites, currently totalling over a million websites now hosted on the Duda platform.

I asked Duda why it was so popular with agencies.

They answered that there are five reasons why agencies choose Duda:

Agencies can build and maintain sites twice as fast compared to any other platform.

In addition, by integrating our platform directly into their service agencies can automate workflows, such as instant site creation, data collection, content management & more.

Duda offers numerous built-in tools that help agencies drive success for their clients without relying on third-party plugins.

Duda’s platform is regularly updated and maintained, ensuring a secure environment for websites.

Agencies don’t have to worry about keeping up with security patches or updates, as Duda handles this automatically.

Duda’s white-label capabilities allow agencies to fully brand the platform as their own, offering a cohesive and professional experience for their clients.

Duda provides dedicated customer support, ensuring agencies have access to expert assistance whenever needed.”

In short, Duda makes it easier for agencies to grow their business by making it easy to service more customers.

Brian Lewis, CEO of WebAct Inc (LinkedIn profile), shared why he is enthusiastic about Duda:

“With Duda we have all of our clients under one dashboard where we can manage everything in a single location.

For the development side of things, we can create custom widgets and apps and do custom API integrations with ease.

The ability to customize the experience for our clients and agencies is very helpful for integrating a custom solution or vertical.

For example, an automotive company may need a custom filter that connects to their software to upload vehicle information as well as having the users of the website search the entire inventory.

We have been using Duda for 11 years now.

Overall the platform is great, it gives us a complete solution for serving our clients.”

Duda Professional Website Builder

Duda calls itself a professional website builder as a way to distinguish itself as a tool for professionals who service clients.

I don’t think it’s fair or accurate when people plant a flag on the ground and proclaim that one platform is better than another.

An apple is an apple and an orange is an orange.

Duda happens to be a fine choice that professionals should consider when planning how to best serve their clients and grow their business.

What Is A Cpu & What Does It Do?

What is a CPU? The CPU or Central Processing Unit is the number-crunching brain of a computer. Everything a computer does, from playing video games to helping you write an essay, is broken down into a set of mathematical instructions. The CPU takes those instructions and executes them. 

The details of how it does this is, of course, much more complicated than that simple explanation. The most important thing you need to know is that the CPU is the main mathematical engine of a computer.

Table of Contents

The (Extremely) Short History Of CPUs

The history of computing is long and complex. It also goes further back into history than digital technology, electronics or even electricity. An abacus is a sort of processor. So are mechanical calculators. The big difference is that these machines can only do one or a few mathematical tasks. They aren’t general purpose processors, which the modern CPU is an example of.

What makes a CPU a general purpose calculation device is the use of logic. In 1903 Nikola Tesla patented electrical circuits known as gates and switches. Using these circuits, you could build devices that perform logical operations, where you could have the machine act on certain conditions. 

In the mid- to late- 1940s William Shockley, John Bardeen and Walter Brattain invented and patented a device called a transistor, while working at Bell Laboratories. The transistor is the basic building block of a CPU. Transistors are relatively tiny computer components. The transistor is such an important invention that the three inventors were awarded a Nobel Prize for it.

A CPU consists of one or more microchips. This is an important invention because billions of transistors can be packed into a single CPU. This creates incredibly powerful mathematical engines.

How Do CPUs Work?

The entire principle of a CPU is based on binary code. Human beings tend to represent numbers using a system called base 10 or the decimal system. The place values of each digit in a number go up by a factor of ten. So “111” contains one hundred, ten and one.

Computers and their CPUs can’t understand base 10 at all. Transistors work on the principle of either being on or off. Which means the logic gates you build from them can also only work with these two states. This is why, fundamentally, CPUs run on binary code. This number system has different place values. Instead if 1, 10, 100, 1000 and so on, the place values are 1,2,4,8,16,32,64,128 and so on. 

So in binary “111” would be 7 in decimal numbers Since you add 1,2, and 4 together. If any of the numbers are a zero, you simply skip it and add the place value of the next 1. This way you can express any decimal value. Just note that binary numbers are often read from right to left, so the “1” place value would be at the far right.

Let’s put it in a table to make it crystal clear:

Binary Place Values1248163264128256The decimal number 7 in binary111000000

Can you see why it adds up to the number 7 in decimal? Let’s do the number 23:

Binary Place Values1248163264128256The decimal number 7 in binary111010000

So 111 is “7”, but “11101” is 23 because the fifth place value in binary is 16. Pretty cool, right? You can express any possible number that can be written in decimal this way. Which means computers built from transistors can work with any numbers as well.

How Are CPUs Made?

The production process of modern CPUs is also, as you’d expect, pretty complex. The basic process involves growing large cylinders of silicon crystal. Its semiconductor properties make it ideal for building a binary integrated circuit.

These large crystals are sliced into thin wafers. The wafers are then “doped” with another chemical to fine tune its properties. The nano-scale circuitry is then etched into the wafer surface using light using a process known as photolithography.

CPU Design and Performance

CPUs are not all made equal. The first proper ancestor of the modern CPU, the Intel 8086, had about 29 000 transistors in its integrated circuit. Today, a processor like the Intel i99900K has just over 1.7 billion transistors. The denser the logic circuits of a CPU, the more complex and higher the number of instructions it can perform per clock cycle. 

Hang on, “clock cycle”? Yes, that’s the other major component of CPU performance. A CPU runs at a particular frequency, with each pulse of the CPU clock a cycle of calculations are done. If you take the same CPU and double it’s clock speed then (in theory) it should perform twice as fast. 

That 1978 Intel 8086 ran at 5Mhz when it was launched. That’s five million clock cycles per second. The Intel i9-9900K? It starts at 3.6 chúng tôi 3600 Mhz, with the option to ramp things up to 5000 Mhz when possible.

To add yet another wrinkle to CPU performance, modern CPUs actually contain multiple “cores”. Each core is actually an independent CPU itself. It’s typical to have at least four such cores these days, but lately the norm has been for mainstream computers to have six or eight cores. High end professional computers may have in the region of a 100 CPU cores. 

Having multiple cores means that the CPU can perform multiple sets of instructions in parallel. Which means our computers can do many things at once without issue. Some CPUs have “multithreaded” cores. These cores can themselves handle two separate tasks each. In Intel CPUs this is branded as “hyperthreading”.

So the total performance of a CPU comes down to a combination of:

There is, of course, more to it than these four main points. However, those are the four main considerations for making a CPU perform well.

The Role of the CPU in Your Computer

The last thing we have to cover is what job the CPU plays in your computer. It is, after all, not the only integrated circuit microchip in your computer. For example, GPUs (graphics processing units) are often even more transistor-dense than a CPU.

They need their own cooling and power supply, as well as memory. It’s like a small extra computer! The same can be said for the chips that control your sound, USB and hard drive traffic. So why is the CPU special? These are the main reasons:

It can process ANY instruction, a GPU only does certain types of processing

It ties all the other components together, pushing and pulling data to make your computer work

The CPU is involved with all work the computer is asked to do to some extent

What Technology Is Used In An Api?

An application programming interface is, in short, a set of tools that allows programmers to make their products cooperate. Honestly, there is no need for you to try to comprehend the art of creating a working API. You can use a credible program to create your own API. The blockchain API allows you to save time, effort, and money while creating an API.

What is an API?

As was stated above, it’s a set of tools. You can also compare it to an agreement. There are two parties in this kind of agreement: a client and a server. The client makes a request, and the server responds. An API is a mediator.

On the World Wide Web, APIs allow you to easily access multiple resources simultaneously that are only available on the side of another software application or server. And this is what makes an API a universal tool.

Types of APIs

The API didn’t always exist. Its appearance on the market was a technological revolution and brought many changes to the online world. It has been around for a while, and its evolution provides an effective communication process between programs that use each other’s functions and resources.

RPC APIs

One of the simplest API paradigms is in which the client calls the execution of a block of code on the server. RPC is an ancestor of SOAP.

SOAP APIs

It is a service that uses the SOAP protocol to exchange messages between servers and clients. However, the messages must be written in XML following strict standards. Otherwise, the server will return an error.

SOAP can be used with SMTP, FTP, HTTP, and HTTPS protocols. Most often — with HTTP as the most universal: it is supported by all browsers and servers.

REST APIs

REST is an architectural style, not a protocol. More of a set of rules for writing code. In fact, it is based on agreements. REST reinforcement is an official standard. A web service built on all the requirements and limitations of the architectural style can be called a RESTful web service.

REST supports several formats besides XML: JSON, TXT, CSV, HTML.

REST does not use data conversion during transmission. Data is transmitted in its original form — this reduces the load on the web service client but increases the load on the network.

What is an API Based On?

Strictly speaking, APIs are not based on any technology. APIs are written algorithms that make apps, websites, and programs work and cooperate.

APIs use programming and markup languages.

What Markup Languages Are Used in an API?

Python

A python is an excellent tool for working with APIs. It is used to create software applications, write tests and backend web applications, and automate tasks in system administration. It suits neural networks and big data analysis.

Java

With the help of the Java API, the work can be controlled by computer systems, and programmers’ participation is not required. Using the API, software companies can update workflows to make them faster and more efficient. Because Java APIs can easily access software components, there is much more flexibility in delivering data and services (used for programming for android).

JavaScript

Allows API calls directly from the user’s browser, bypassing the server while saving traffic and computing resources. In addition, it gives access to some features that are not available for calling from the server. A high-level scripting programming language built into the browser that allows you to create functionality for web pages/applications.

How Does an API Work?

Interaction with the API in the code occurs through objects that serve as containers for the information that the API works with (contained in the object properties) and implement the API’s functionality (contained in the object methods).

Conclusion

All in all, an API is a must-have for the successful usage of any website or app. APIs are algorithms that are based on coding only. It’s a set of phrases and commands in a particular programming language.
