An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.
Hence, the operating system (OS) provides utility software designed to perform specific tasks. Some of the tasks it performs are;
A. Establishing an Internet connection.
B. Coordinating tasks between programs.
C. Configuring peripheral devices.
D. Monitoring security.
