The Operating System as a Resource Manager. Internally an Operating System acts as a manager of resources of the computer system such as processor, memory, files, and I/O device.

Answer 2

Answer:

Some major activities that an Operating System performs for resource management are −

• The Operating System manages all kinds of resources using schedulers.

• CPU scheduling algorithms are employed for better utilization of CPU

Explanation:

• Program that is running on a computer is known as a process. The OS manages how software processes share the system’s resources.
• Most software needs to save data to a storage device, such as a hard disk. Imagine that there are three processes running at the same time, and all three processes save data regularly. The processes might send requests to save data when the storage device is already in use. The operating system should manage these requests so that all three processes can save data.

• By switching the CPU among processes, the operating system can make the computer more productive.
