System software is a type of software that is designed for providing a platform to other software. It runs a computer’s application program and hardware of the system. This software acts as an interface as between user applications and hardware. An operating system is an example of system software. System software consists of programs that are written in low-level languages that are used for interacting with hardware at a basic level.
It is one of the most important types of software required for administering resources of computer systems. Such software runs and functions internally with hardware and application software. It runs in the background and manages every function of the computer itself. Since it runs at the basic computer level, the system software is written in a low-level language; therefore, it is known as low-level software.
1. Operating System
It is a type of software that is responsible for managing software resources, hardware, and common services for computer programs. The operating system is an intermediary between programs and computer hardware for hardware functions such as memory allocation and input-output. There are different types of operating systems. These include single and multi-user, distributed, embedded, real-time, single-time, and multitasking.
2. Server
It is a type of computer software that offers functionality for other programs called ‘clients’. The architecture of a server is known as client-server network. Servers provide several functionalities called services, such as sharing resources and data among multiple clients. A single server serves multiple clients, and a single client serves multiple servers.
3. Programming Language Translators
These programs convert code written in one programing language into another. Such translators are useful when you want to run the code written in one programming language onto a machine that understands another language. It converts the code from an older language into a new one to keep the code updated. These are of two types: compiler and interpreter.
3.1 Compiler
Compiler is a system software that is used for the translation of computer codes from source programming language to target language. It translates human-readable code into binary language of 0s and 1s for computers to understand this language and accordingly take actions. It aims to increase the efficiency of the target code and optimize in terms of space and time.

3.2 Interpreter
This software is directly executed. It performs instructions written in a scripting or programming language. It does not require the program to be previously compiled into a machine language program. It translates high-level instructions into an intermediate form, and then it executes them.
It is a fast system software since an interpreter does not require going through the compilation stage during which machine instructions are generated. An interpreter continuously translates the program till the time an error is found. Whenever an error is detected, the interpreter stops executing. This allows easy debugging.
4. Firmware
This is a system software embedded within the hardware device. It controls the device and performs functions that are essential for the computer system. Firmware is stored in ROM due to which it cannot be modified or deleted. In some devices, firmware can be updated using updates from USB or the manufacturer’s device.
It is a specific type of software that allows low-level control for device hardware. Firmware such as BIOS also consists of the basic functions of a device. They also provide hardware abstraction services to higher-level software such as operating systems. It is a non-volatile type of memory in computer. Some are permanently installed and cannot be altered after manufacture.
Components of System Software?
Different components of system software work together to ensure computers run efficiently, and support user applications. This enables effective communication between software and hardware.
Operating System (OS): Manages hardware resources, provides a user interface, and facilitates communication between hardware and software.
Device Drivers: Enable communication between peripheral devices (like printers or keyboards) and the computer’s operating system.
Utilities: Tools that help manage, maintain, and optimize the computer system, such as disk cleaners, antivirus programs, and backup software.
Programming Languages: Compiler and interpreter software that converts programming code into machine-readable language for execution.
Middleware: Software that bridges communication between different applications and facilitates distributed computing.
