Hardware Components Quiz

Central Processing Unit (CPU) Elements

• The three elements associated with the CPU are the Arithmetic Logic Unit (ALU), Control Unit (CU), and Registers.
• The ALU performs all arithmetic and logical operations.
• The Control Unit directs operations of the processor and coordinates instructions from memory.
• Registers provide a small amount of high-speed storage for immediate data and instructions.

Hardware Component for Computation

• The Arithmetic Logic Unit (ALU) is responsible for actual computation and logical operations in a computer.
• It handles addition, subtraction, multiplication, division, and logical operations such as comparisons.

Components of Hardware

• Hardware components include input devices (like keyboards and mice), output devices (like monitors and printers), storage devices (like hard drives and SSDs), and the motherboard.
• It also encompasses the CPU, RAM, and various peripherals that facilitate computing tasks.

Role of Main Memory

• Main memory, typically RAM, temporarily stores data and instructions that the CPU accesses during operation.
• It provides fast read and write access to support active applications and processes in real time.

Functions of Input and Output Devices

• Input devices allow users to enter data and commands into the computer, such as keyboards, mice, and scanners.
• Output devices convey results from the computer to the user, including monitors, printers, and speakers.
• Together, they facilitate interaction between the user and the computer system.
