The system software is a special software usually developed by the computer manufacturing companies to communicate with the hardware device.

In this article , you will learn what is system software , why computer needs system software , different types ,  its functions and other related important topics .

What Is System Software ?

System software refers to a set of programs and applications that manage and control the operations of a computer system. It is designed to provide a platform for running other software applications, as well as manage computer hardware and system resources.

System software includes operating systems, device drivers, utility programs, and other tools that enable the computer to perform various tasks. Operating systems, for example, are responsible for managing hardware resources, controlling input and output, and providing a user interface. Device drivers enable communication between the operating system and specific hardware devices, such as printers and keyboards. Utility programs, such as antivirus software and disk cleanup tools, help users maintain and optimize their systems.

Generally, system software plays a crucial role in ensuring that computer systems operate efficiently and reliably, and that applications can be developed and run smoothly.

System Utility Programs

The operating system internally needs a special software called system software to communicate with the hardware devices and perform some special task for the system maintenance .

So , we can define the system software as a low level program specially designed to provide an interface to manage and control hardware components. This also includes system maintenance and management functions performed by the operating system.

These system program software generally written in low level language  such as assembly language or C language that can easily be programmed  for hardware interaction.

Difference Between Application Software And System Software

The system software and application software are both essential components of computer architecture.

The system software handles the communication with hardware components. Whereas, the application software provides an interface to the user to communicate with the system to perform various tasks.

Depending upon the functionality requirements, the user can install the application software components.

Operating System

What Is Operating System ?

The operating system is the most commonly used system software . The operating system is an essential component of the computer system and the first program that gets loaded into the main memory RAM every time the computer is powered on.

The operating system provides the user an interface to perform various tasks on the computer system. The operating system effectively functions as a over all in charge of the computer and handles some of the most important functions.

Operating System Booting Process

The operating system is the first system software that gets loaded into the main memory RAM. This BIOS is responsible to initiate and complete the system booting process.

The BIOS is another system software. The BIOS gets activated when user starts the computer. The BIOS than initiates the system booting process. After the completion of the booting process the operating system takes over the system control.

Operating System Booting Process , BIOS , How Computer Starts

The operating system handles some of the most critical functions essential for computer system to function.

The operating system functions include resource management , process management , system security , command interpreter , file management , input output functions and the memory management.

Device Driver

What Is Device Driver ?

The operating system internally communicates with various hardware components through a special system software designed to manage and control a specific hardware component. This software is called a device driver.

The operating system consist of number of device drivers to drive the most commonly used hardware components .

However , some times the user may have to upload the device driver if it is not available in the operating system.

Computer System Architecture

The device drivers are usually provided by the computer manufacturing companies and the operating system will ask for the driver if that device is plugged into the computer system.

System Software

Compiler And Interpreter

The computer system understands only machine code instructions in binary due to its architecture at the hardware level . The binary code consist of patterns of only two numbers that is either 0 ( zero ) or 1 ( one ).

However , the computer CPU can execute only machine code instructions in binary . And therefore , the computer program written in any high level programming language must be first converted into binary machine code .

This conversion process from high level program code to low level machine code is called as program compilation. The  computer programs are compiled with the help of a compiler .

Program Compilation
Program Compilation Interpreter

A compiler is a type of system software which converts the high level program into the low level executable machine code . Similarly , for interpreted language , an interpreter converts the program to machine code line by line.

Both compiler and interpreter perform the same job except the compiler converts the entire program whereas the interpreter converts line by line.

Features Of The System Software

All the important system software are preinstalled into the computer system by the computer manufacturer. For example, the BIOS comes as a firmware built into the system.

The main function of the system software is to provide as an interface between the system user and the computer hardware.

The important features of the system software  are :

High Execution Speed

The System software programs are developed in low level programming languages .

And therefore , the system can execute low level programs at very high speed as compared to high level programs.

Difficult To Corrupt

The most critical system software are provided as firmware into the system architecture. The firmware cannot be easily corrupted since that are tied to a specific hardware.

Further, the operating system also has its own system security built into the operating system software that protects the system.

Multiple Services

The system software are designed to provide the service to the operating system, other software components and also to the system user.

The operating system can manage and control the hardware components as well as other hardware devices connected to the computer through system software.

The system user can also access some utility software components necessary for system maintenance and control.

Essential Part Of Computer Architecture

The system software components are essential part of the every computer system. It performs some critical functions and are important part of the computer system organization and architecture.

Examples Of System Software

The examples of system software include following software components.

System Software - Firmware BIOS

The BIOS  and UEFI is another essential system program that is responsible for the system booting process.

The computer system becomes available to the user to perform any task when the operating system is fully loaded and operational.

And therefore , when the computer is switched on , the CPU’s first task is to load the operating system into the main memory RAM. This process is called system booting.

The CPU initiates the system booting process with the help of another system program called the BIOS. The BIOS stands for Basic Input Output System.

Computer BIOS

The BIOS completes the system booting process by loading  the operating system into the main memory RAM and hands over the control to the operating system.

The BIOS is called firmware because it is placed into the ROM ( Read Only Memory ) chip . The firmware ROM is part of every motherboard components.
