what is system software

System software refers to a type of software that provides a platform for other software applications to run on a computer or device. It acts as an intermediary between the computer hardware and the application software. The main purpose of system software is to control and manage the computer resources, such as memory, processors, and input/output devices, and provide a stable and consistent environment for application software to operate. System software includes the following types of software:

• Operating System (OS): An operating system is the most important type of system software, and it acts as the foundation for all other software applications to run on a computer. The main functions of an operating system include managing memory and processing, controlling the input and output of data, and managing files and directories. Some examples of popular operating systems are Microsoft Windows, Apple macOS, and Linux.

• Device Drivers: These are small programs that allow the operating system to communicate with specific hardware devices, such as printers, keyboards, and graphics cards.

• Utilities: These are programs that help maintain the stability and efficiency of a computer system, such as disk defragmenters, antivirus software, and backup software.

• Firmware: This is a type of low-level software that is stored on a device's non-volatile memory, such as flash memory or read-only memory (ROM). It provides basic instructions to control the device's hardware, and is often used in devices such as routers, printers, and embedded systems.

System software plays a critical role in the functioning of a computer or device, as it provides the underlying infrastructure for other software applications to run. Without system software, application software would not be able to perform their intended functions and the computer would not be able to operate properly. System software is usually pre-installed on a computer or device, and is usually updated periodically to improve performance and fix security vulnerabilities.
