Suggested January 2024 Terminal Vs Powershell Vs Command Prompt Difference Explained

In these circumstances, using a command-line interface will help you get the job done much faster than with a GUI-based operating system. There are several different options available when it comes to using a command-line interface on Windows 11/10 computers. In this article, we cover three of them – PowerShell, Command Prompt, and Windows Terminal — explaining how they differ from each other and when they should be used.

Differences between Terminal, PowerShell, and Command Prompt

When you’re working with a computer, you’ll often find yourself in situations where you will have to access the command line. Many Windows users are accustomed to launching programs by typing their names into the Start menu search box, but using this method won’t help you use the command line. Instead, you’ll need a different method to access the command line when you need it. This article will give you an overview of three command-line interfaces and explain what makes them different and which one you should use. However, before we begin, let’s first take a look at what a command-line interface is.

What is a Command Line Interface?

The command Line Interface is a system of text-based instructions that is used for running applications, managing files, and interacting with the computer. These things may seem tedious to some, but they’re actually very important for your computer to operate efficiently. Each interface has its own special functions, and they allow you to interact with your computer. To provide you with a better understanding of these user interfaces, this guide will provide you with the details of each so you can decide which one is right for you. Read on to learn more about the terminal vs PowerShell vs Command Prompt difference explained.

What is PowerShell?

Windows PowerShell is another great Windows application that is capable of performing all the tasks that Command Prompt can. It incorporates the functionality of the old CMD program with a new scripting language, as well as system administration features. The PowerShell cmdlets offer administrators and users the ability to perform complex tasks with the help of reusable scripts. It is a powerful tool for system administrators and IT professionals that includes every cmdlet you could possibly need for administration, so there is no reason for you to use CMD anymore.

What is Windows Terminal?

Windows Terminal is a powerful application that supports most command-line shells and was introduced with Windows 10. One of the most interesting aspects of the application is that it brings to Windows the command-line tool BASH (Bourne Again Shell), which was previously only available on Linux operating systems. Furthermore, Windows Terminal boasts a new tabbed interface capable of running multiple commands at the same time. The Unicode and UTF support in Windows Terminal allows you to use special characters and emojis from other languages. It supports GIFs and offers a variety of color schemes and background images as options for customizing the interface. Furthermore, the program includes the Cascadia-code font, allowing programmers to expand their horizons.

Terminal vs PowerShell vs Command Prompt difference explained

Windows PowerShell, Command Prompt, and Terminal offer similar functionality as the dedicated tools. The way a command is executed in Windows PowerShell and within the Windows Terminal’s PowerShell window is the same. Similarly, executing a command in a dedicated CMD window works equally with running it at the Windows Terminal command prompt.

Among task-based command-line tools, PowerShell and Command Prompt are both useful for automating system administration tasks, but their functionalities and capabilities differ quite a bit. The Command Prompt shell is based on the same principles as DOS and was introduced along with Windows NT. PowerShell, on the other hand, is a task-based command-line shell and scripting language based on the .Net framework that is mainly used for batch processing and system management.

Here are a few reasons why PowerShell has an edge over Command Prompt. So while Microsoft has developed PowerShell as a way to improve CommandPrompt, why do we need Windows Terminal? Does Windows Terminal actually need to exist?

Windows Terminal is an open-source project that offers an intuitive tabbed user interface. The application supports multiple command-line processes in parallel. Thus, you can open multiple tabs at the same time, and execute PowerShell and Command Prompt commands simultaneously. The program also supports Unicode and UTF, which lets you insert emojis and other special characters. Furthermore, the app includes GIFs and configuration options, so you can play with different color schemes and backgrounds to customize it.

In its open-source nature, Windows Terminal is expected to continue developing indefinitely. A couple of years ago, Microsoft announced its support for BASH inside Windows, which allowed users to run Ubuntu and Terminal finally making that possible.

Terminal, PowerShell, and Command Prompt Interface

Terminal, PowerShell, and Command Prompt all have command-line interfaces, which let users use them easily and intuitively. If you look at the interface of these programs, you will find Command Prompt has the simplest interface. This will take you back to the early days of web pages when you could type commands into fields on black backgrounds with white fonts.

Powershell nslookupy overviews

The powershell nslookup it’s the important one for the network management tools and it is the Bind name for accessing the software applications in the servers. Mainly it focuses on the Internet-based computing systems for planned to deprecate the host and other proxy modes, dig, etc. When we use nslookup it does not use the operating system for accessing the domains and it resolves in any type of server modes like both localhost and globally made access. If we use the domain name system, it has some set of rules and libraries for tunning and performing the queries it’s may operate with different manners and situations. For each vendor, its varied depends upon the requirement and versions provided from the system additionally it includes the output of the other data sources which related to the user information’s getting by the other input data contents which related to the configurations that may require by the user end. The Network Information Service(NIS) it’s the main source of the nslookup its related to the host files, sub-domains, and other proxy-related things. The nslookup may vary it depends upon the operating system and system requirements because of the network bandwidth and other related things like pinging the url for to checking the network data packets.

Powershell command for NSLookup

Generally, it has more than a single way to perform the domain name system like DNS query for achieving the nslookup commands to operate the tool and to fetch the DNS  record of each of the names specified with the domain resolver for Resolve-DnsName. When we perform this operation first it creates the empty array so it does not initialize the value then once the operation is triggered the each value will be stored as a separate memory allocation. If we use any programming loops iterating the values and the powershell will pass more focus on each data item including variables, operators, and even methods both default and customized methods. For each iteration of the loops it creates the temporary object and then it swaps to the original with the constant memory location. We can also utilize the nslookup command to resolve the ip to a hostname with commands like “nslookup %ipaddress%” in the screen for validating the datas to the powershell server for each and every session the object will be newly created once the session is closed or terminate it will automatically exist on that time.

Use Nslookup in Powershell

The nslookup command is equivalent power of the Domain name System Resolver it’s mostly configured and used in the cmdlet that can be performed using the DNS System the query cannot be fetched and it will not be retrieved from the particular domain name. We can use this in the powershell not only in that it is equivalent to the same and different DNS server. Because we can use the DNS with the specified and for network troubleshooting to identify the issue. We also would use the ping command to check the network connections and the host sites for checking, validate the datas with the specific IP address and which has performed the DNS reverse lookup for validating the datas it has configured and called the reverse proxy using fetch the query DNS and AD with the IP networks for a group of computers will join to the Active Directory Services in the domain for Active computers that already configured using the IP Address in the every User account of the computer system. Generally combining a group of hostnames for every IP address that can be done within the loop also iterates the datas. The recording datas are stored using the DNS record if any of the IP data is mismatched or not assign properly at that time it will throw an error like “IP not resolve” so that we can check the ip address of the specified system.

DNS NsLookup in PowerShell

PowerShell command for NSLookup

Some of the PowerShell commands will use the hostname to finding the IP address with some parameters. Like that below,

Based on the above commands we can retrieve data from the server.


The nslookup is the command for getting the information from the Domain Name System(DNS) server with the help of networking tools using the Administrator rights. Basically, it obtains the domain name of the specific ip-address by using this tool we can identify the mapping of the other DNS records to troubleshoot the problems.

Windows 11 Upgrade Vs. Clean Install (Difference)

On Windows 11, an upgrade means switching from an older to a newer version of the operating system and preserving your files, settings, and apps.

A clean install means erasing the hard drive and installing a fresh copy of Windows 11 without preserving settings, apps, and files.

Usually, a clean installation is better than an upgrade for new setups, upgrades, or reinstalls.

On Windows 11, you have at least two installation methods, including an “in-place upgrade” or “clean install.” If you need to know which one to choose, you are not the only one. In this guide, we’ll look into the differences between the two to help you decide.

Windows 11 upgrade vs. clean install Upgrade

The “upgrade” or “in-place upgrade” is the most popular method to install a new version of the operating system, in this case, Windows 11. The process will create a copy of the current installation, replacing the setup with a newer version while migrating your settings, applications, and files.


Usually, if the current installation works correctly, you can use the in-place upgrade to move to a newer version of Windows while saving time since you won’t need to reinstall your applications or re-apply your preferred settings. (This is the fastest method to upgrade.)

If there’s a problem during the upgrade, the setup can automatically roll back to the previous installation, so you can troubleshoot the issue and keep using the device.

Also, if you don’t like the new system or experience problems you can’t resolve after the installation, you have ten days to roll back to the previous version. (However, this option will not keep any system changes or applications installed after the upgrade.)


However, an upgrade can cause problems due to custom configurations, buggy drivers, and compatibility issues with specific applications (such as old or poorly designed programs) from the current installation.

You also have to consider that during the process, the setup will try to bring everything from the old to the new installation, which means that some problems may come along with the upgrade. For example, the setup may transfer unnecessary Registry entries, files, and programs you no longer need. The upgrade process can also bring viruses and other types of malware to the new installation of Windows 11.

Furthermore, after an upgrade, typically, there’s always something you will need to fix or reconfigure manually.

Upgrade options

Microsoft offers two ways to upgrade a system. You can perform an in-place upgrade to a new version through the Windows Update settings. Alternatively, you can also use the Installation Assistant tool that works like “Windows Update.” However, the program was designed to upgrade systems when the “Windows Update” settings are not working.

These methods are only available to upgrade from Windows 10 to 11 or from an older version of Windows 11 to a newer one, such as from version 21H2 to 22H2.

Clean install

A “clean install of Windows 11” is always recommended for new setups, upgrades, or reinstalls. This method takes the most time and doesn’t keep your files, settings, and apps, but it’s the method that is more likely to complete the installation successfully.


When you perform a clean installation, you can erase and format the hard drive to apply a fresh installation of Windows 11.

Since the process deletes everything on the drive, you won’t encounter compatibility issues with apps or problems with drivers that will cause the installation to fail.

After the installation, you will have to complete the out-of-box experience (OOBE) to choose your preferences and create an account.

A clean installation also means that the setup won’t try to bring anything from the previous version, fixing performance and battery issues, system and compatibility problems, and more. Also, this process will help you remove virtually any malware on the computer.

Another reason to choose a clean installation version and upgrade is that a fresh setup doesn’t include any bloatware, only the inbox apps from the original image of Windows 11.


If you encounter issues, you must have a full system backup to restore the previous version since there’s no rollback option. You’ll need to restore your files from a file backup manually. Also, you will need to reinstall and reconfigure all your applications, which can take a long time.

After the installation, you may need to check and install missing drivers that Windows 11 could not detect automatically. However, on branded devices, this is a straightforward process using the “Windows Update” settings or the driver assistant application available from most manufacturers.

Clean install options

Microsoft offers different methods to perform a clean installation of Windows 11, but creating a bootable USB media that you can use to start the computer is the best option.

If you want to perform a clean install, you can create a Windows 11 bootable USB media using the Microsoft Media Creation Tool or the third-party tool known as Rufus. You can follow these instructions to complete a Windows 11 clean install from USB and every other method available.

Windows 11 also includes the “Reset this PC” option with the option to erase the drive to start with a fresh setup. However, this process doesn’t upgrade the system to a newer version. Instead, it’s a feature to reinstall the same version of the operating system to fix issues. Also, similar to the upgrade process, this method can cause problems.

Finally, the clean installation problems will work to upgrade any compatible system to Windows 11 regardless of the previous version of the operating system, including Windows 11, 10, 8.1, 7, Vista, XP, Linux, etc., because the previous setup is erased before the new installation.

Installation method you should choose

The Windows 11 clean installation process is always the method you should try to choose. It takes the most time, but it gives you a piece of mind that you will be using a setup without issues or bloatware and free of malware.

If you don’t have the time and everything is working correctly or are not a technical user, you can choose the in-place upgrade process since it’s the easiest and fastest upgrade method (if everything goes according to plan).

Data Science Vs. Decision Science: What’s The Difference?

Data science Vs decision science: A primer on what makes them unique and what unites them

Data science and decision science are two different yet closely related disciplines. For a company or enterprise with a number of operational areas, certain characteristics overlap between them. This exactly creates confusion among aspiring data scientists and decision scientists. They take the functional areas of either fields for granted only to repent later. Having similar-sounding names and common expertise areas, it is not uncommon that they are mistaken for one another. Decision science and data science are two-data driven fields that have risen to prominence in the past few decades and therefore it is equally important to understand the differences by companies and individuals equally. While data science is all about providing insights, decision science is about putting those insights into an application to achieve better outputs. Let’s deep dive into the data science Vs decision science question.

What is Data Science?

Data science essentially involves processing large chunks of data using various mathematical, statistical, and analytical tools and machine learning algorithms. Data scientists interpret data for a better understanding of underlying data from a gigantic number of transactions. The ultimate goal is to provide actionable insights for the decision-makers to choose a course of action. Technically speaking, they write complex algorithms and build statistical models. Data science applications broadly lie in the area of finance, banking, healthcare, e-commerce, education, manufacturing etc.

What is Decision Science?

Decision science is about sketching the optimal strategy to solve the problem at hand with the insights provided. In a way, it involves taking a 360-degree view of the business challenge by taking into account the type of analysis, visualization methods, behavioral understanding, and feasibility of the strategy. Technically speaking a decision scientist applies complex quantitative data-driven methods combined with cognitive science and managerial capabilities. As decision science involves taking course-changing steps, it is mainly applied to public healthcare and policy, law and education, military science, environmental regulation, business, and management.

Key Comparative differences between Data Science and Decision Science View on Data:

For data scientists, data is a tool for innovation for interpreting and analyzing situations. It helps in building result-oriented solutions thereby leading to adopting data-driven methods. Decision scientists, in contrast, use data as a tool only as a suggestive mechanism for taking decisions. They apply data to design not one but different approaches to a problem. Though data is equally important, the mechanism differs vastly. While data scientists are focused on finding insights, decision scientists use data to reveal those insights.


A data scientist’s USP lies in processing structured as well as unstructured data and putting the derived information into an easily understandable format so that it reveals a certain pattern. On the other hand, decision scientists though do not work with big data, but using the insights, they arrive at a principled framework for decision-makers to align with a certain mindset.


The challenge lies in complexity. Data scientists have to process large amounts of data and hence have to address the issues related to it such as the development of sourcing, data security protocols etc. For decision scientists, given the techniques they apply are complex, the lack of reliable data and the right data environments stand as hindrances.

Pcie 4.0 Vs. Pcie 3.0: What’s The Difference?

In 2023, PCI-SIG announced the arrival of peripheral component interconnect express (PCIe) 4.0, but products that support this standard didn’t officially hit the shelves until last year. The technology has quickly become mainstream, with more and more people shifting to products that support this newest iteration, such as Samsung 990 PRO.

In light of this technology upgrade, you may be wondering, “What does PCIe do, and do I need to upgrade my devices to PCIe 4.0?” Because both the transfer rate and bandwidth doubled between PCIe 3.0 and PCIe 4.0, you’ll probably want to give the new standard a look, especially since we’re finally seeing PCIe 4.0 support from chip vendors.

What is PCIe?

At its most basic, PCIe is an interface that lets you connect high-speed components — such as add-on chips, memory, graphics cards and storage—to your motherboard. They are available in five different types of cards that fit into the motherboard: x1, x2, x4, x8 and x16.

These designations indicate that the cards have a corresponding number of slots that function as lanes for data to travel to and from the peripheral. One side of the lane sends data, and the other side receives it. If your PCIe interface is a PCIe 4.0 x8, that means it can handle PCIe 1.0, 2.0, 3.0 and 4.0 devices with up to eight different lanes. You’ll be able to do more with less in this case, since a PCIe 4.0 x8 slot can handle almost exactly what a PCIe 3.0 x16 slot can currently handle.

[related promo]

Another helpful aspect of PCIe devices is that they are backward and downward compatible, so a PCIe 2.0 x2 will still work with a PCIe 4.0 x8 interface. Likewise, you can put a PCIe 4.0 device into a PCIe 3.0 slot, and it will work, albeit at PCIe 3.0 speeds.

What’s the difference between PCIe 3.0 and PCIe 4.0?

The biggest change between PCIe 3.0 and PCIe 4.0 is the data transfer rate, or throughput. PCIe speed gets an upgrade in the newer iteration. PCIe 3.0’s throughput is 1GB per second per lane, providing an overall data transfer rate or bandwidth of up to 32GB/s total. PCIe 4.0 doubles the 3.0 throughput rate per lane, giving users a transfer rate of up to 64GB/s.

Why does this matter? The faster the throughput, the better performance you’ll see from peripherals such as solid state drives (SSDs). A recent PC Gamer story heaped the highest praise on the standard, saying, “If you want the absolute fastest drives available, then PCIe 4.0 SSDs are the way to go. They’re quicker than any PCIe 3.0 drive and will make large file transfers for such things as video editing lightning fast.”

If you’re looking to use a lot of cloud-based resources, or if you’re doing input/output-intensive work with local applications, you’ll see better performance with PCIe 4.0 than you would with a 3.0 interface.

Do I need PCIe 4.0?

SSDs that utilize a PCIe 4.0 interface will load applications and games quicker, and if your operating system is installed on one, you’ll see boot rates go up too. Samsung 980 PRO and 990 PRO SSD both feature PCIe 4.0, and the 980 PRO was the preferred storage device of MAINGEAR, which manufactures custom gaming rigs that require fast load times to support high-graphic games with as little latency as possible. Speed aside, PCIe 4.0 consumes less energy, which means devices run cooler and quieter.

Command Prompt is a native command-line shell for Windows NT-based systems, such as Windows XP, Windows Vista, Windows 7, Windows 8 and Windows 10. Also available in Windows Server 2003, 2008 and 2012.

Its function is to execute the commands entered in its dialog box. Basically, CMD commands are tasks performed autonomously with scripts and .bat files.

What is the use of Command Prompt?

The program performs troubleshoot, solves certain errors and has several administrative functions.

Officially, Command Prompt is referred to as Windows Command Processor. In other less official settings, it’s called:

command shell

cmd prompt


Command Prompt is not a DOS prompt or MS-DOS itself. Some people make this mistake because it has certain resemblances. Still, Command Prompt is a Windows program that can use the command lines available in MS-DOS.

How to open Command Prompt

Of course, like any other program, before you start using it, you should know how to open it first. Fortunately, for Command Prompt, the procedure is really simple.

Just type “command prompt” in the search box from the Start menu. It will appear as the first search result. For an added comfort, you can just type “cmd”, the result would be the same.

Still, using the shortcut is way faster and easier. As you can see, even with Run, there are additional steps to be followed.

Keep in mind that most of the repair commands can only be executed if you run it with administrator rights. Here’s what to do if you can’t run Command Prompt as administrator on Windows 10.

How to use Command Prompt

In order to use Command Prompt, you must enter a valid command along with the needed parameters required by the task at hand.

There’s no room for mistakes when you enter a command. The Command Prompt will not recognize a command if you misspell a word, so, it will fail to execute or worse, it will execute a wrong command.

The syntax is also very important. For example, if you want to delete a certain document, but by mistake, you leave a space, the Command Prompt would delete the entire folder.

Speaking of “del” command, you can use it to delete a certain type of file. Just write “*”, followed by the extension of the file (eg: .jpg, .mp3, .iso etc.).

You can use a large variety of commands. The most commonly used are chkdsk, format, ping, del, shutdown, help, and copy.

So, as you can see, the commands are logical and intuitive. For example, “chkdsk” stands for “check disk”. It is a very useful tool, where Windows will check your disk for errors. Also, chkdsk will fix certain issues.

For more details about this tool, check out our guide on how to use CHKDSK.

Moreover, the Command Prompt is probably the most efficient tool for fixing corrupted files.

In short, the Command Prompt is a tool where you can do almost everything, from repairing your computer, running programs or even deleting your files.

If CMD is not working properly on your computer, check out our collection of troubleshooting guides.
