Hardware Components Quiz

Study Notes

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.
