Understanding Operating Systems Concepts

What is the primary function of a CPU in a computer system?

• To store data permanently

• To execute instructions and process data

• To manage network connections

• To provide power to the system

Which type of memory is considered volatile?

• Hard Disk Drive (HD)

• Read-Only Memory (ROM)

• Random Access Memory (RAM)

• Solid State Drive (SSD)

What is the main characteristic of a multitasking operating system?

• It can execute multiple tasks simultaneously

• It can only execute one task at a time

• It does not require a CPU

• It is only used in mobile devices

Which of the following is a non-volatile storage medium?

• RAM

• Cache

• Hard Disk Drive (HD)

• CPU registers

What is the primary role of cache memory in a computer system?

• To store data permanently

• To increase the speed of data access for the CPU

• To connect the computer to the internet

• To provide backup power

Which architecture is commonly associated with the concept of stored-program computers?

• Harvard Architecture

• John von Neumann Architecture

• RISC Architecture

• CISC Architecture

What is the function of CPU registers?

• To store large amounts of data permanently

• To hold small amounts of data temporarily for quick access

• To manage network traffic

• To provide graphical output

Which of the following is an example of a monotasking operating system?

• Windows 10

• MS-DOS

• Linux

• macOS

What is the main difference between volatile and non-volatile memory?

• Volatile memory retains data without power, non-volatile does not

• Non-volatile memory retains data without power, volatile does not

• Volatile memory is slower than non-volatile memory

• Non-volatile memory is used only in mobile devices

Which component of a computer system is responsible for executing instructions?

• RAM

• CPU

• Hard Disk Drive (HD)

• Network Interface Card (NIC)
