‘What is System Software?’ It is the interface between hardware & application software. The files & programs that make up your operating system makes the System software. Examples are such as the most familiar, Microsoft Windows & Google Android. It is an essential ‘programming language.’ The users, programmers, developers use it to operate electronic devices. There are different types of software that make up the operating system. For example, Windows Operated PC, we have ‘BIOS.’ ‘BIOS’ co-ordinates hardware, input, and output usability. Plus, how the PC will turn on. To give you more Infos, our discussion ‘What is System Software?’

‘What is System Software?’And how does it work?

As mentioned earlier, the operating system allows parts of a computer to function together. In the case of software, prominent are Microsoft Windows, Linux, and Android. Tasks transfer data from memory to storage. Plus, provide rendered output to a screen or monitor. It serves as a platform to run high-level system software. Also, it helps the application software. 

Before knowing about ‘What is System Software?’ We need to know about the work of OS. The operating systems also have a central part of the system. This defines an ‘Interface’ for programming. Here the application is called API (Application Programming Interface). Also, it controls the hardware connected to or built into the computer. For this reason, it helps the PC to run correctly and finish the task.   

A user interface works as a medium to let us interact with a computer. It can either be a command-line interface (CLI) or a Graphical User Interface (GUI). Since the 1980s, the CLI gradually became replaced. MS-DOS was old, and an invention of new hardware, the “mouse,” required Windows to think. Device drivers, including ‘BIOS’ and device firmware, give basic functionality to run the hardware.

The importance of system software:

We know a computer consists of software & hardware parts. Thus, to run that hardware parts, the System software is necessary.It will create an interaction between the computer and the hardware parts of the PC. Also, with the user. Now, why is this interface required? Ok, we humans speak in English or other languages. But, the machine or computer understands only one language. The language is a binary language consisting of zeros and one. When comes the question of ‘What is System Software?’ Then comes the name of binary language.  To work with computers, we need an interpreter. Here say that the interpreter is acting as an interface. 

The System software here is doing the ‘interpreter’ job between the user and the device. It converts all the instructions in English to machine-understandable form. Users can easily interact with the computer. Also, they can give it necessary commands and instructions because of the system software. Also, System Software is essential in the software industry. See more about this here.



We will discuss some essential criteria for ‘What is System Software?’ in this section. First off, we have the Operating System. This helps us in the best use of all hardware & software of a device. Then, we have the ‘Programming language.’ This language helps to transform the instructions. Developers made programming language where a computer system can compile and execute. Next, we have the Communication software. It allows us to transfer data & programs from one computer system to another. The last one is the Utility programs. ‘Utility programs’ help users to perform maintenance and routine tasks. We also have device drivers. Drivers allow the input or output devices to function with the CPU. Therefore, all these programs make up the System Software of a specific device. 


System software categories and their importance:

In this section, we will provide a vivid description and importance. Beside, ‘What is System Software?’We have categories. There are different categories of system software. They are: 1) operating system, 2) language processor, 3) device drivers. 


The operating system: It is responsible for operating all hardware parts on a computer. The operating system is required so that these hardware parts can function adequately. Plus, they can follow our commands. The operating system is the first software loaded into the system. (When we switch on our PC.) For such reason, the operating system plays an essential part than others. If our system does not have an operating system, then it will not work. Because the operating system manages memory. Deals with the processor, the speed in which it will work, files, etc. 

Language processor: Language processor will convert a high-level language into an assembly level language. It is also called machine level language. So that the PC can complete the commands efficiently. In other words, system software that converts source code to object code is a language processor. There are three types of language interpreters in a system. They are: a) assembler, b) interpreter, c) compiler. You can learn more about the language processor here.

Device drivers: As the name suggests, the ‘device driver’ will take care of all the devices attached to the PC. We can also say the system software controls & monitors a specific device’s functioning on the computer. The device driver interacts with the operating system. For that reason, these devices will work properly. When you attach a new machine with your PC, it is necessary to install the driver. The driver’s installation is vital so that the operating system knows how it can manage.



System Software is closer to the system. Generally, it is written in a low-level language. The system software is complicated to program and observe. The operating speed is fast, no doubt. However, there is less interaction in the case of operation. In fact, users never interact with system software as it works in the background. The size it takes up is small, but it is quite tricky to manipulate. It starts running when the device is powered on plus, runs until the user turns it off. System Software is a general-purpose software. System software makes up the entire operating system.  When operating system installation happens, the system software is installed at the same time.

The system software is capable of running independently. But some things are needed to remember for running software. As an example, PC games are also a type of software. We cannot run a PC game on Microsoft Mobile. Not even in any Android smartphones. This is because the mobile cannot run a computer program. Plus, the configuration wasn’t like to use hardware and software like a Computer. The exe, dll, and other extensions do not work that way. Though some users think that it may be possible as technology advance. Also, smartphones have advanced. The system software is independent of the application software. The system software plays a significant role in the effective functioning of a system.



Throughout history, there have been many known names in the computer world. Besides, ‘What is System Software?’ comes the names of the companies. MS-DOS, Windows 95, Mac OS, LINUX all these were the apex of evolution &  noteworthy. In the 90s, we had Windows 95, 98 & then the NT and ME in 2000. The most used popular OS until the XP is Windows 98. This is a better or advanced version of the 95. The Windows 95 is the precursor of mouse operated programs & video games. Then in the mid-2000s, we got Windows XP. The XP is the most compatible OS in Microsoft History. XP can run almost any program that is far backward or advanced for its time. For example, many gamers played games of 2008 with highly realistic graphics on XP.

On the other hand, old gamers played the very classic games of 1995 that run on Windows 95 only. Then we proceed on to the next era where the video games are in the HD universe. The most popular System Softwares till now are the Windows 7,8 & 10. Though Windows 7 is a better OS for gaming & much more compatible than Windows 10. According to several PC users, Windows 7 has kept its fame for reliability. Plus, it has good gaming performance. As for mobile phones, they started becoming much more evolved ‘smartphones,’ there is the Google Android, Apple iOS. Windows also got into smartphones making quite an unpopular gesture. It was not user friendly. Microsoft dominates on PCs. On the other hand, Google reigns Android smartphones. On the other hand, Apple produces both MacBooks & iPhones. Both have compatible OS, Mac OS & iOS are intertwining.


Clearing the confusion about the question ‘What is System Software?’

There arises some confusion when you’re asking ‘What is System Software?’ It is an essential programming language. Where users, programmers, developers use this to operate electronic devices. The system software is not an ‘Operating System.’ The collection of it makes up an Operating System. This is anything like Task Manager, Services, ODBC setup. Anything that writes to the registry can also be System software. Also, date & time settings, display settings, hardware add/remove, etc. There is only one program running on our device at one time: the operating system. Everything else is a method of applying the computer’s native abilities to solve problems, run applications. Being frank, Windows is a System Software, and MS Office is application software. 

Using a very advanced OS such as Android 9 in an old Android phone may create problems. For example, the Redmi 3 will have adverse effects. Plus, the phone will slow down the basic functions. This is mostly applicable to computers. But for smartphones, the scenario is quite different. Everything we see on the menu and the home screen. These are application software, also known as “apps.” Alongside that, many of them ask, ‘what are the main types of computer software?’ These are: number one is this. Another one is an application program. For this reason, it plays an essential criterion in a PC or smartphone.  



  • How can you tell apart a system software and an operating system?

Ans: It makes up the entire operating system. The task manager is it. But according to Microsoft, Windows as a whole is this, whereas Microsoft Office is application software.


  • How can you use this for run programs? 

Ans: It starts running when the user switches on the device. It will stop whenever the user switches off the device. Plus, it is continuously running in the background when we use our device.


  • Can you change or upgrade this to improve my smartphone’s performance?

Ans: Naturally, the performance becomes enhanced, but it all depends on the hardware of the phone. Plus, it may face some problems and will slow down the basic functions of the smartphone. 


  • Can we run PC games on a Microsoft smartphone?

Ans: No, this is because the mobile cannot run a computer program. The configuration is not like that. Smartphones do not use hardware and software like a Computer. Here, the exe, dll, and other extensions do not work that way.


     5       What other things that a System software includes?

             Ans: System software may consist of system utilities. For example, 

                 disk defragmenter, development tools, and system restore. 



It is an essential component to run a PC, Smartphone, or tablet. Even Smart TVs have ‘Operating Systems.’ The ‘operating system’ becomes upgraded or updated due to the changes and updates in it. Better product leads to a more upgraded operating system. For example, Windows 10 is all popular and compatible, where everyone is using it on their PCs. However, now you can tell ‘What is System Software?’ Soon the older ones are being replaced. The taking of place of the older ones by the newer ones is called evolution.
