Operating Systems

The purpose of an operating system is to provide an environment in which a user can execute programs in a convenient and efficient manner.

The primary objectives of an operating system are to make computer system convenient to use and to utilize computer hardware in an efficient manner.

An operating system acts as an intermediary between a user and computer hardware by providing an interface that allows the user to interact with the hardware and execute programs.

Some basic tasks performed by an operating system include receiving input from the keyboard, processing instructions, and sending output to the screen.

The main functions of an operating system include providing an interface between the user and the hardware, managing system resources, scheduling tasks, and facilitating communication between software and hardware.

An operating system makes a computer system convenient to use by providing a user-friendly interface, handling input and output devices, managing files and folders, and facilitating multitasking and multiprocessing.

An operating system utilizes computer hardware in an efficient manner by managing system resources, such as memory and CPU, allocating them to different processes or programs based on their priority, optimizing resource usage, and minimizing wastage.

Some examples of basic tasks performed by an operating system include receiving input from the keyboard, managing memory and storage, handling device drivers, managing processes and threads, and providing a graphical user interface (GUI) for the user.
