Basic Concepts of Computer Systems

What are the four basic functions of a computer?

• Input, Processing, Output, Storage

• Typing, Printing, Scanning, Saving

• Running, Storing, Connecting, Computing

• Loading, Executing, Editing, Deleting

What is the primary function of a computer's CPU?

• Store all user data permanently

• Display graphical output on the monitor

• Execute instructions from programs

• Manage input and output devices

What is the purpose of RAM in a computer system?

• Store data permanently

• Provide temporary storage for active processes

• Control all hardware components

• Manage network connections

What is an example of an input device?

• Printer

• Speaker

• Scanner

• Monitor

Which of the following is NOT an output device?

• Monitor

• Speaker

• Mouse

• Printer

Which part of the CPU directs operations and controls execution?

• Control Unit (CU)

• Arithmetic Logic Unit (ALU)

• RAM

• Hard Drive

What does the Arithmetic Logic Unit (ALU) do?

• Directs the flow of data

• Performs calculations and logical operations

• Stores temporary data

• Controls input/output devices

What is the relationship between the ALU and CU in a CPU?

• The ALU processes calculations, while the CU directs operations

• The CU stores all data, while the ALU retrieves it

• The CU is responsible for calculations, while the ALU directs operations

• The ALU and CU have the same functions

What is the main function of an operating system?

• Run applications without hardware

• Manage hardware resources and provide services for applications

• Store files permanently

• Execute only one program at a time

Which of the following is NOT an operating system?
