Sql Group By Multiple Columns

Introduction to SQL GROUP BY Multiple Columns

SQL GROUP BY multiple columns is the technique using which we can retrieve the summarized result set from the database using the SQL query that involves grouping of column values done by considering more than one column as grouping criteria. Group by is done for clubbing together the records that have the same values for the criteria that are defined for grouping. When a single column is considered for grouping then the records containing the same value for that column on which criteria are defined are grouped into a single record for the resultset. Similarly, when the grouping criteria are defined on more than one column then all the values of those columns should be the same as that of other columns to consider them for grouping into a single record. In this article, we will learn about the syntax, usage, and implementation of the GROUP BY clause that involves the specification of multiple columns as its grouping criteria with the help of some of the examples.

Start Your Free Data Science Course


SELECT column1, column2,..., columnm, aggregate_function(columni) FROM target_table WHERE conditions_or_constraints GROUP BY criteriacolumn1 , criteriacolumn2,...,criteriacolumnj;

The syntax of the GROUP BY clause is as shown above. It is the optional clause used in the select clause whenever we need to summarize and reduce the resultset. It should always be placed after the FROM and WHERE clause in the SELECT clause. Some of the terms used in the above syntax are explained below –

column1, column2,…, column – These are the names of the columns of the target_table table that need to retrieved and fetched in the resultset.

aggregate_function(column) – These are the aggregate functions defined on the columns of target_table that needs to be retrieved from the SELECT query.

target_table – Name of the table from where the result is to be fetched.

conditions_or_constraints – If you want to apply certain conditions on certain columns they can be mentioned in the optional WHERE clause.

criteriacolumn1 , criteriacolumn2,…,criteriacolumnj – These are the columns that will be considered as the criteria to create the groups in the MYSQL query. There can be single or multiple column names on which the criteria need to be applied. We can even mention expressions as the grouping criteria. SQL does not allow using the alias as the grouping criteria in the GROUP BY clause. Note that multiple criteria of grouping should be mentioned in a comma-separated format.

Usage of GROUP BY Multiple Columns

When the grouping criteria are defined on more than one column or expression then all the records that match and have the same values for their respective columns mentioned in the grouping criteria are grouped into a single record. The group by clause is most often used along with the aggregate functions like MAX(), MIN(), COUNT(), SUM(), etc to get the summarized data from the table or multiple tables joined together. Grouping on multiple columns is most often used for generating queries for reports, dashboarding, etc.


Consider a table named educba_learning having the contents and structure as shown in the output of the following select query statement –

SELECT * FROM educba_learning;

The output of the execution of the above query statement is as follows showing the structure and contents of educba_learning table –

Now, we will group the resultset of the educba_learnning table contents based on sessions and expert_name columns so that the retrieved records will only a single record for the rows having the same values for sessions and expert_name collectively. Our query statement will be as follows –

SELECT sessions, expert_name FROM educba_learning GROUP BY sessions, expert_name ;

The output of the above query statement in SQL is as shown below containing the unique records for each of the session, expert name column values –

Note that while using the grouping criteria it is important to retrieve the records on which the grouping clause is defined. Using the above statement for retrieving all the records will give the following error if the SQL mode is set to only full group by –

SELECT * FROM educba_learning GROUP BY sessions, expert_name ;

The output of the above query statement in SQL is as shown below-

Let us execute the following query statement and study the output and confirm whether it results in output as discussed above –

SELECT SUM(sessions), expert_name FROM educba_learning GROUP BY sessions, expert_name ;

The output of the execution of the above query statement is as follows –

We can observe that for the expert named Payal two records are fetched with session count as 1500 and 950 respectively. Similar work applies to other experts and records too. Note that the aggregate functions are used mostly for numeric valued columns when group by clause is used.


We can group the resultset in SQL on multiple column values. When we define the grouping criteria on more than one column, all the records having the same value for the columns defined in the group by clause are collectively represented using a single record in the query output. All the column values defined as grouping criteria should match with other records column values to group them to a single record. Most of the time, group by clause is used along with aggregate functions to retrieve the sum, average, count, minimum or maximum value from the table contents of multiple tables joined query’s output.

How To Check Your Apple Warranty Status

This article explains how you can check your Apple product warranty status and eligibility to purchase an AppleCare product.

Apple designs, manufactures and sells various products, including the iPhone, the iPad, the Mac, the iPod, the Apple Watch, the Apple TV, the AirPods, the HomePod, and the other Apple-branded accessories (keyboards, etc).

Apple product warranties

Apple offers warranties on new or refurbished Apple hardware. When you buy an Apple product, it usually comes with the Apple Limited Warranty. This warranty, basically, says that Apple warrants your products against defects and workmanship under normal use for one year.

Apple offers additional warranties. You extend (and upgrade) your protection if you purchase AppleCare+ or the AppleCare Protection Plan. The pricing for this additional coverage differs. For example, Apple’s extended warranty service costs $199 for the iPhone X, XS, and XS Max, offering two-year coverage including accidental damage. You can buy this when you buy your device or within the 60 days of your purchase.

Related articles:

Check your coverage

There are three ways to look up your warranty status:

1. My Support site: You can view all of your devices and their coverage online if they use the same Apple ID. Here is how:

Open Safari or any other browser on your device.

Once you log in, you will be able to view a list of all of your Apple devices.

2. My Support app. One of the ways that Apple offers support is the My Support app which is available on the App Store. You can download and use this app to check your warranty options (you can also contact Apple support via this app). Here is how:

On your iPhone or iPad, download the app.

Once installed, open the app and sign in.

Tap your name and avatar.

Tap Check Coverage.

Here you can see all of your devices and their coverage. If your device has no coverage, it will say “Out of Warranty”. If you tab your device, you will see more details about it.

3. The Check Coverage website. And the last method is to the Check Coverage website. You may want to use this method especially if the device that you are checking its warranty status is not useable. For example, the device won’t turn on or its screen is broken so you cannot use the methods above. For this method, however, you will need to know the device’s serial number. The next section explains how you can find your device’s serial number even if it is not working.  Here is how you can use this website to check your warranty options:

Open Safari or any other Internet browser (e.g., Chrome) on your device or computer.

The new page will display your coverage.

How do I find my serial number?

So you want to know your product’s serial number.

If you can turn on the product:

If you cannot turn on the product:

If you have your receipt or invoice, your serial number will be there.

If you have the original packaging, it may contain its serial number.

Most Mac (including desktop and notebook) models include their serial numbers on the underside of them.

AirPods serial numbers are on the underside of the lid.

Some Apple Watch models’ serial numbers are printed on the band slot.

Check your product’s surface. For example, you can find the serial number on the back of some iPhone, Apple Watch and iPad models.

You can find the serial number on the SIM tray on some iPhone and iPad models.

If you have a computer, you can find your serial number bu going to the Apple ID website. Here is how:

Sign in using your Apple ID and password.

Scroll down and find the Devices section.

A popup will display the details.

Use Taskbargroups To Group Taskbar Shortcuts In Windows 10

The taskbar is one of the most used elements in Windows 10 on any day. It is the easiest way to launch apps that you use frequently. However, when you have too many shortcuts on the taskbar, it becomes a mess. If you are anything like us, you might have pinned multiple web browsers and productivity suites’ icons to the taskbar.

Using TaskbarGroups to group Taskbar Shortcuts

Since Window 10 does not have a default option to group taskbar shortcuts, we will use a third-party app to do this: TaskbarGroups.

TaskbarGroups is an easy-to-use Windows 10 customization app. This app lets you add groups of shortcuts to the taskbar as well as to the desktop. In this article, however, we will focus on how TaskbarGroups would help you create a sleeker, cleaner, and comfortable taskbar interface. The best part? TaskbarGroups is free to use on Windows 10 devices.

The developer, Jack Schierbeck, has released the source code of the program on GitHub as well. Developers may be interested in tweaking the source code, but everyday users can download the executable version of the TaskbarGroups app from GitHub itself. The app received its latest update three days back, adding support for vertical taskbars, multiple monitors, and even hidden taskbars.

Altogether, TaskbarGroups is a great way to create taskbar shortcuts on Windows 10. Now, let’s see how to do that.

Why Group Taskbar Shortcuts?

As we said, taskbar shortcut groups are great for saving space and organizing the elements. Furthermore, if you can create the right set of shortcut groups, you can increase your productivity. Users who have a small-screen Windows 10 device, such as the Surface Go or other 2-in-1s, can also benefit from the taskbar shortcut grouping options. Even if you don’t need these benefits, it’s good to have a tool to tweak how the taskbar is behaving on your Windows 10 PC.

How to use TaskbarGroups On Windows 10

You can follow the steps shown below to add taskbar shortcuts on your Windows PC.

First, you have to download the TaskbarGroups app from GitHub and install it on your Windows 10 PC. Just like we said, it’s a minimal app that does not take up much space/resources from your computer. Therefore, you can finish the installation process in a few seconds.

TaskbarGroups will show you a window where you need to provide details of the taskbar shortcut group. First, you have to enter the group’s title, the maximum width of the group, and the shortcuts you want to add.

For instance, you can give a title like ‘Web Browsers’ to one group and add all the browsers you frequently use on your computer. TaskbarGroups does not have a limit on how many shortcuts you can keep on a single taskbar group.

That’s it. This is how you add a group of shortcuts to the taskbar.

Following this process, you can add as many groups as you want. To put this into perspective, you can add so many apps, say 20, within just 2 or 3 groups. By doing so, you get to save a lot of space too.

It also works on the desktop!

Is TaskbarGroups safe to use?

Well, TaskbarGroups comes from a credible developer, and you may not have to worry about malware or other malicious elements within the app. There is even an option to compile the source code if you know how to do that. Rest assured, installing and using TaskbarGroups is unlikely to cause any harm to your computer or the Windows 10 experience.

In fact, we believe that TaskbarGroups will help you enhance the Windows 10 experience. Because the app uses a simple function to show the shortcuts, there aren’t many complexities involved. So, you won’t have trouble keeping this app running at all times.

The Bottom Line

There you have it: the easiest method to create and use your taskbar shortcut groups on Windows 10. This method works without fail on all Windows 10 devices and doesn’t overload your system, either. It means you can enjoy the convenience of shortcut groups on your taskbar without compromising speed or system resources.

Do Network File Systems Pre


In a networked computing environment, file systems allow users to access and manage files across different computers and storage devices. Network file systems (NFS) are a type of file system that enables remote file access and sharing between machines over a network. In NFS, a client machine can access files stored on a remote server as if they were on its local file system. One common question that arises regarding network file systems is whether they pre-fetch data to improve performance. In this article, we will explore concept of pre-fetching in network file systems and provide examples of how it works.

What is Pre-fetching in Network File Systems?

Pre-fetching is a technique used to improve performance of file systems by anticipating data that a user might access and proactively loading it into memory. This approach is based on observation that data access patterns are often predictable, and certain files or blocks of data are likely to be accessed soon after others. By loading this data into memory before it is requested, file system can reduce latency of file access operations and improve overall system performance.

Pre-fetching in network file systems works by caching frequently accessed files or blocks of data on client machine’s local file system. When a file is opened, file system first checks if requested data is already present in cache. If it is, data can be quickly retrieved from cache without need to access remote server. If data is not in cache, file system will fetch it from server and also pre-fetch additional data that it predicts will be accessed soon.

Examples of Pre-fetching in Network File Systems

Pre-fetching is a technique that is used in a variety of network file systems. Here are some examples −

NFSv4 NFSv4 is a popular network file system used in many enterprise environments. It includes a feature called layout hints, which allows clients to provide hints to server about which files or portions of files are likely to be accessed soon. server can then use this information to pre-fetch data and make it available to client before it is requested.

AFS Andrew File System (AFS) is a distributed file system that also includes pre-fetching capabilities. AFS pre-fetches data based on access patterns of individual users and groups, as well as overall behavior of system. It also includes a feature called Venus Fetch Agent, which can pre-fetch data in background without disrupting other system operations.

CIFS/SMB Common Internet File System (CIFS) and Server Message Block (SMB) are network file systems used in Microsoft Windows environments. These file systems include a pre-fetching feature called read-ahead, which allows client to pre-fetch data that it expects to be accessed soon. read-ahead feature can be tuned to adjust amount of data that is pre-fetched and degree of aggressiveness used.

Benefits and Challenges of Pre-fetching in Network File Systems

Pre-fetching can provide significant benefits for network file systems. By proactively loading data into memory, pre-fetching can reduce latency of file access operations and improve overall performance of system. This can be particularly important for large files or for operations that involve many small files. Pre-fetching can also help to reduce load on network by reducing number of requests that need to be sent to server.

However, pre-fetching can also pose some challenges for network file systems. For example, pre-fetching requires additional resources, such as memory and CPU cycles, which can affect overall system performance. Pre-fetching can also be difficult to tune, as effectiveness of pre-fetching depends on specific access patterns of individual users and system as a whole. In addition, pre-fetching can lead to increased network traffic, particularly in situations where pre-fetched data is not actually needed. This can be particularly problematic in low-bandwidth or high-latency network environments, where cost of sending unnecessary data over network can be high.

Another potential challenge with pre-fetching is that it can lead to stale data in cache. If data is pre-fetched but never actually accessed, it can remain in cache for an extended period of time, potentially leading to inconsistencies between cache and server. This can be particularly problematic for applications that require up-to-date data, such as databases or content management systems.

Here are some additional points to consider regarding pre-fetching in network file systems

Pre-fetching can also be useful for reducing load on network. By pre-fetching data on client machine, number of requests that need to be sent to server can be reduced, resulting in less network traffic.

Pre-fetching can be particularly beneficial in situations where network latency is high. In these situations, time it takes to fetch data from server can be significant, and pre-fetching can help to mitigate this delay by ensuring that data is already in memory when it is needed.

To use pre-fetching effectively, it is important to carefully analyze access patterns of individual users and system as a whole. This analysis can help to identify files or portions of files that are most likely to be accessed and can inform pre-fetching algorithm.

Pre-fetching can be challenging to tune, particularly in dynamic environments where access patterns are constantly changing. In these situations, it may be necessary to continuously monitor system and adjust pre-fetching algorithm to ensure optimal performance.

It is important to carefully manage pre-fetching cache to avoid stale data. This can be done by setting appropriate cache expiration times and by periodically checking cache for data that is no longer needed.


Pre-fetching is a powerful technique for improving performance of network file systems. By proactively loading data into memory, pre-fetching can reduce latency of file access operations and improve overall system performance. However, pre-fetching can also pose challenges, particularly in low-bandwidth or high-latency network environments. To use pre-fetching effectively, it is important to carefully tune pre-fetching algorithm to specific access patterns of individual users and system as a whole. With careful tuning and management, pre-fetching can be an effective tool for improving performance of network file systems.

Web 3.0: The Evolution Of Web

This article was published as a part of the Data Science Blogathon.


The third generation of the internet has now firmly taken hold in ern retelling of Web history. Web 3.0 will usher in a new era of decentralized blockchain-based architectures as we transitioned from decentralized protocols (Web 1.0) to centralized, monopolistic platforms (Web 2.0).

With Web 3.0 as the prevailing narrative, the grasp of power will dissipate from a small number of powerful Web 2.0 firms and return power to the people.

In contrast to today, when tech giants dominate the platforms, in Web3, users will have ownership shares in platforms and applications.

Significance of Web 3.0

The vast majority of designers and builders will use cutting-edge tools, integrate into autonomous organizations, and take part in this new economy.

Decentralized Autonomous Organization is the guiding principle of Web 3. (DAO). Users will be able to govern their own data on a decentralized, fair internet thanks to Web3.

This would get rid of the extortionate rents charged by the big platforms and get people away from the fundamentally faulty ad-based monetization of the user-generated data paradigm that has come to define the current digital economy.

Prerequisite for Developing Web 3.0 Architecture

The current architecture, which has a front-end, intermediate layer, and back-end, will need to be modified for Web 3.0 from a technological standpoint.

For processing blockchains, persisting and indexing data in blockchains, peer-to-peer interactions, and other tasks, will require backend solutions.

In a similar vein, managing a backend with a blockchain will be required of the middle layer, also known as the business rules layer.

Evolution of the Web Web 1.0-World Wide Web Begins Web 2.0-The Social Web

There are a few factors to take into account when describing web 2.0. Internet programs that let users communicate, cooperate, and express themselves online are referred to by the phrase. It’s essentially a better version of the first global web, marked by the shift from static to dynamic or user-generated content, as well as the rise of social media.

Rich web applications, web-oriented architecture, and the social web are all part of the Web 2.0 paradigm. It refers to changes in the way web pages are designed and utilized by people, without any technical changes.

“Web 2.0 is the business revolution in the computer industry caused by the move to the internet as a platform, and any attempt to understand the rules for success on that new platform.”–     Tim O’Reilly.

Web 2.0 can be described in three parts:

Rich Internet application (RIA): It specifies if the experience delivered from the desktop to the browser is “rich” in terms of graphics, usability/interactivity, or features.

Web-oriented architecture (WOA): It specifies how Web 2.0 applications disclose their functionality so that other apps can use and integrate it, resulting in a significantly richer range of applications.

Key Features of Web 2.0

Folksonomy: Users can collaboratively classify and find information (e.g. “tagging” of webpages, images, videos, or links) using a free classification system.

Software as Service (SaaS): APIs were built by Web 2.0 sites to facilitate automated usage, such as by a Web “app” (software application).

Mass Participation: With nearly universal web access, concerns are being differentiated beyond the conventional Internet user base (which tended to be hackers and computer enthusiasts) to a broader range of consumers.

Use Case Applications of Web 2.0

Hosted Services (Google Maps)

Web Applications (Google Docs)

Video-Sharing Sites (YouTube)

Wikis (Media wiki)

Blogs (Word press)

Interactive Social Networking/Media (Facebook)

Micro Blogging (Twitter)

Pros of using the Web 2.0

Information is available at any time and in any location.

A wide range of media. (Images, Videos, Web Pages, Text/Pdf) It– Very user-friendly.

Learners can actively participate in the creation of knowledge.

Has the ability to form dynamic learning communities.

Everyone is both the author and the editor, and every edit can be monitored.

Simple to use.

The wiki is updated in real-time, and it provides researchers with extra resources.

It allows for real-time communication.

Cons of using Web 2.0

People rely heavily on the internet to communicate.

It is keyword driven.

Failure to remove material that is no longer relevant.

Many con artists and hackers.

Intelligence is lacking.

Web 3.0-The Decentralised Web

Web 3.0 is the third generation of internet-based services or an intelligent web. The expression was created in 2006 by John Markoff. Although it is typically understood to be a reference to the semantic Web, he continued, “There is no easy consensus about what Web 3.0 means”.

The semantic Web, while not a more accurate term, refers to technology that improves Internet use by comprehending the meaning of what users are doing rather than merely the way pages link to each other.”

With significant developing technology trends like semantic web, data mining, machine learning, natural language processing, artificial intelligence, and other such technologies centered on information that is machine-assisted, Web 3.0 is expected to be more connected and smarter.

The web as a whole should be better designed to cater to a user’s interests and needs. Self-descriptions or similar strategies can be used by developers and authors individually or in partnership to ensure that the information produced by the new context-aware application is meaningful to the user.

Key Concepts in Web 3.0

Decentralization: “To post anything on the web, no approval from a central authority is required; there is no central controlling node, and hence no single point of failure…and no ‘kill switch!” This also entails freedom from censorship and surveillance on an ad hoc basis.”

Bottom-up design: “Rather than being written and controlled by a small group of experts, the code was created in full view of everyone, enabling maximum participation and experimentation.”

Key Features of Web 3.0

Decentralization: This is a fundamental principle of Web 3.0. In Web 2.0, computers search for information using HTTP in the form of unique web addresses, which are stored in a fixed location, usually on a single server. Because Web 3.0 allows information to be retrieved based on its conten be kept in several locations at the same time, making it decentralized. This would deconstruct the vast databases currently maintained by internet behemoths like Meta and Google, giving people more power. Users will retain ownership control of data generated by disparate and increasingly powerful computing resources, such as mobile phones, desktop computers, appliances, vehicles, and sensors, with Web 3.0, allowing users to sell data generated by their devices.

Semantic Web: Let’s take a step back and define semantics first before creating the semantic web. The study of how words relate to one another is known as semantics. The semantic web is a technology that enables computers to interpret massive amounts of Web data, including text, grammar, transactions, and linkages between people.

3D Graphics: Compared to the straightforward, two-dimensional web, Web 3.0 will provide a more believable, three-dimensional cyberworld. Online gaming, as well as Web 3.0 websites and services like e-commerce, real estate, tourism, and other industries, will benefit from a new degree of immersion thanks to 3D visuals.

Trustless and permissionless: Web 3.0 will be trustless (i.e., the network will allow members to engage directly without going via a trusted intermediary) and permissionless, in addition to being decentralized and built on open-source software (meaning that anyone can participate without authorization from a governing body). As a result, Web 3.0 applications will run on blockchains, decentralized peer-to-peer networks, or a combination of both, and will be referred to as dApps (decentralized apps).

learning: Through technologies based on Semantic Web ideas and natural language processing, machines will be able to understand the information in the same way that people do in Web 3.0. Machine learning will also be used in Web 3.0, which is a branch of artificial intelligence (AI) that combines data and algorithms to mimic how humans learn while continuously improving accuracy. These capabilities will allow computers to deliver faster and more relevant results in a variety of sectors, such as medical research and novel materials, as opposed to the current focus on targeted dvertising.

Connectivity and ubiquity: Information and content are increasingly accessible and omnipresent with Web 3.0, which can be accessed by many applications and a growing number of daily objects connected to the internet, such as the Internet of Things.

Use Case Applications of Web 3.0

Social Networks: Social networks have a significant impact on how we live our lives and change the way we connect, communicate, and build communities. The new generation of social networks, however, is not without issues. They have internal agendas, are restrictive, and are censored. Governments of major companies may also utilize social networks to try and shape and control the opinions of their users. The functioning of the social network will be entirely altered by Web 3.0. Social media networks won’t be subject to any restrictions thanks to the implementation of blockchain. Regardless of geographic restrictions, anyone can join.

Exchange Services: As they offer a flawless user trade experience without worrying about any hacks or transparency, decentralized exchanges are progressively gaining favor. This also implies that there is no central authority and no owner-side conflict of interest. To streamline their services, they primarily use a variety of decentralized finance tools. As we already know, Web 3.0 is all on decentralized exchange and trust.

Messaging: Since the day we first started using the internet, messaging has been a part of our daily life. Well, for the majority of us, the choice is between Facebook Messenger and WhatsApp. One other type of messenger is Telegram, which is mostly used by businesses, startups, and other types of professional activity. On the other side, the government also frequently uses centralized systems to manage its network of intelligence to trace down signals.

Storage: The storing of data involves a lot of ingenuity. However, Web 3.0 technologies like blockchain and big data can transform the way data is now stored. As common users, we store data online on Google Drive and other cloud storage services. For the businesses, it’s a whole different scenario because they prefer a more reliable and centralized system to keep their important data.

Insurance and Banking: One of the most contaminated sectors of our society is the insurance and banking industry. For instance, is managed according to the profit-making mindset. The chains of negativity are also present in the banking industry. Overall, it is safe to state that the current system is flawed and that it must be made more open and secure if people are to prosper inside it. Blockchain technology has the potential to revolutionize both the banking and insurance industries. This technology has a wide range of applications, and its effects are more apparent than initially anticipated. Transparency, security, and retractability are just a few of the blockchain capabilities that will be utilized in the transformation. This means that fraud in the banking or insurance industries will not be conceivable.

Streaming (Video and Music): The streaming sector is significant. Additionally, it is predicted to expand more quickly in the next years. You are already familiar with the major players in our area as a user.

Remote Job: Given that we prefer working from home over being in an office, it is rather fascinating to observe where we are headed. Whatever the causes, the centralized remote job platforms fall short of expectations. These issues can easily be solved by decentralized remote job/freelance networks.

Browser: Using a web browser, we browse the Internet. We require a browser that adheres to the decentralized Web’s philosophical aspect in order to explore web 3.0. In terms of safeguarding users, the most recent browsers are also not entirely secure. Computers can become infected when users visit infected websites. If they are not sufficiently constructed in accordance with current security standards, browsers can also leak information. Your browser, for instance, keeps data on your location, hardware, software, connection, social media accounts, and more. The add-ons that these contemporary browsers provide make the users vulnerable as well. The answer is to utilize a decentralized browser that uses blockchain technology to create a better ecology.

Pros of using the Web 3.0

Anti-monopoly and Pro-privacy: Web 3.0 will provide the internet with a pro-privacy and anti-monopoly framework. It won’t encourage the use of centralised platforms. In essence, a full paradigm shift will occur, with decentralisation and privacy as the main themes. The middleman won’t understand the value or need of such a platform.

Secure Network: Web 3.0 features will be safer than those of its forerunners. Decentralization and distributed nature are two reasons that enable this. It will be challenging for hackers or exploiters to access the network. Each of their operations can be monitored and retracted within the network if they are able to do so. Without centralization, it will also be more difficult for hackers to seize total authority over a company.

Interoperability: It is a crucial component of Web 3.0. It will be simpler for applications to function across various platforms and devices, such as TVs, cellphones, smart roadways, and so on, with a decentralised network. The creation of Web 3.0 apps will be simple for developers.

No Interruption in Service: Service interruptions are less likely to occur in distributed systems. It is challenging for attempts at distributed denial of service (DDoS) or other types of service breakdown to have an impact because there is no central entity for functioning. As a result, Web 3.0 is a fantastic platform for sharing data and essential services without having to worry about service disruption.

Permissionless Blockchains: Blockchains without a requirement for a central authority are to be powered by Web 3.0. By creating an address, everyone can join the blockchain and take part. Access to individuals who are historically excluded owing to their gender, income, location, and other factors is made possible via permissionless blockchains. Although there are other blockchains with chúng tôi implies that Web 3.0 won’t be subject to any limitations.

Semantic Web: The semantic web’s features will be hosted by Web 3.0 as well. The previous set of Web 2.0 technologies have been replaced by the semantic Web. It makes it possible to transfer data across many platforms, systems, and community borders. It will serve as a link between various systems and data formats. We will be able to share and use the internet more than ever by utilising the semantic Web.

Cons of using the Web 3.0

Ownership concerns: With internet providers under government control, the internet will still not be decentralized.

Existing website owners will be compelled to upgrade: With the change in the cost model, some services may no longer be free.

Tough to regulate: Newcomers may struggle to understand Web3.0

Easier access to one’s personal and public data: Without privacy policies, it will be easy to gain access to someone’s private and confidential user information.

Comparison between Web 2.0 and Web 3.0

Web 2.0 Web 3.0

Centralized. Application delivery, cloud services, and platform are governed and operated by centralized authorities. Decentralized. Edge computing, peer-to-peer, and distributed consensus increasingly become the norm in Web 3.0.

Fiat currency. Payments and transactions occur with government-issued currency, such as $USD. Cryptocurrency. Transactions can be funded with encrypted digital currencies, such as Bitcoin and Ethereum.

Cookies. The use of cookies helps to track users and provide personalization. NFTs. Users can get unique tokens that are assigned value or provide some form of the perk.

CSS and Ajax. Web 2.0 is defined by layout technologies that provide more dynamic control than Web 1.0. AI. Smarter, autonomous technology, including machine learning and AI, will define Web 3.0.

Relational databases. Databases underpin the content and applications of Web 2.0. Blockchain. Web 3.0 makes use of blockchain immutable ledger technology.

Social networks. Web 2.0 ushered in the era of social networking, including Facebook. Metaverse worlds. With Web 3.0, metaverse worlds will emerge to meld physical, virtual, and augmented reality.

Future for Web 3.0

Web 3.0 is still in the process of being defined. As a result, there are many unknowns regarding what Web 3.0 will eventually look like.

The IPv4 address class, which has a limited amount of web addresses, is used by both Web 1.0 and Web 2.0. In the Web 3.0 era, IPv6 offers a bigger address space, allowing more devices to have their public IP addresses.

Web 3.0’s focus on decentralization, automation, and intelligence will likely continue to be the foundation for what comes next as it evolves and is defined.


As a last thought, I’d want to leave everyone with another example that started this learning journey. According to an analogy from the movie industry, if Web 1.0 represented black-and-white movies, Web 2.0 would be the age of color/basic 3D, while Web 3.0 represents immersive experiences in the metaverse. In the same way that Web 2.0 dominated the global business and cultural landscape in the 2010s, it seems that Web 3.0 will now take the lead in the 2023s. Facebook changing its name to Meta on Oct. 28, 2023, could prove to be an early sign that Web 3.0 is gaining traction.

The most significant aspect of Web 3.0 is that it improves security, trust, and privacy. Many people refer to Web 3.0 as the “decentralized web,” because it will rely heavily on decentralized protocols. Web 2.0, on the other hand, is still the foundation for many of the web apps we use today. Is it possible that Web 3.0 will transform the popular programs you use today? Learn about Web 3.0 and make your conclusions.
