Answer:
System software refers to the underlying low-level software in a computer system that provides basic functionality and support for other software running on a device.
The purpose of system software is to provide basic services and functions for the computer and its applications. This includes tasks such as managing hardware resources (such as the CPU, memory, and storage), managing system files and directories, managing input/output operations, providing security and authentication services, and more. System software acts as an intermediary between the computer's hardware and the higher-level application software, enabling the applications to interact with the hardware and access its resources.
