What is the primary function of an operating system?

• To manage the operations of the computer

• To design the hardware of the computer

• To create application software

• To perform arithmetic calculations

What is the role of the loader in an operating system?

• To execute user commands

• To load the operating system into RAM

• To manage network connections

• To compile software programs

Which of the following is NOT a function of an operating system?

• Interrupt service routines

What does an operating system use to disguise the complexities of managing hardware?

• A simple interface

• A complex algorithm

• A hardware manual

• A programming language

What is the primary function of memory management in an operating system?

• To increase the speed of the CPU

• To allocate specific areas of memory to each program

• To manage the power supply of the computer

• To enhance the graphics performance

What is the purpose of paging in memory management?

• To increase the size of the memory

• To divide memory into fixed size pages

• To enhance the security of the system

• To improve the display resolution

How does segmentation differ from paging in memory management?

• Segmentation uses fixed size pages, while paging uses variable size segments

• Segmentation divides memory into variable length segments, while paging uses fixed size pages

• Segmentation is used for security, while paging is used for speed

• Segmentation is a hardware process, while paging is a software process

What happens when a computer has insufficient memory and a large number of jobs are loaded?

• The computer shuts down automatically

• The operating system swaps pages in and out of RAM, causing performance deterioration

• The computer increases its processing speed

• The operating system deletes some jobs to free up memory

What is an interrupt in the context of computer systems?

• A signal from a software program, hardware device, or internal clock to the CPU

• A method of data storage

• A type of computer virus

• A software application for editing documents

What happens when the CPU receives an interrupt signal?

• It continues executing the current program without changes

• It shuts down immediately

• It suspends execution of the running program and calls an Interrupt Service Routine

• It deletes all data in the memory
