Describe four tasks that are carried out by an operating system.

The four tasks that are carried out by an operating system are:

1. Processor Management — The Processor management function of an OS allocates an important computer resource CPU to various running programs or applications. This function of an OS prepares, schedules, controls, and monitors jobs or processes submitted for execution to ensure the most efficient processing.
2. Memory Management — The memory management function allocates memory to the running processes and de-allocates memory from the process, when it gets completed.
3. Device Managementt — This function of an operating system is responsible for proper handling of input and output devices. This function ensures smooth reading of data from the input devices and sending the data to correct output devices.
4. User Interface — The OS establishes a standard means of communication between users and their computer systems. It does this by providing a user interface and a standard set of commands that control the hardware.
