It acts as an interface between the computer’s hardware and the end user. System software converts instructions that end users give to the computer into a machine understandable language. Examples of system software include operating systems, utility programs, device drivers, and windows systems. The operating system is responsible for the functioning of all the computer’s hardware parts. It is the software loaded into the system when the computer boots up. It manages everything, from the memory, to the CPU, and many other different tasks.
