Computer Fundamentals

The Central Processing Unit (CPU) is regarded as the brain of the computer, responsible for executing instructions and processing data.
Computer fundamentals primarily focus on the basic concepts and components of computing systems, including hardware, software, and system architecture.

Operating System Functions

An operating system (OS) manages hardware and software resources, serving as an intermediary between users and the computer hardware.
The OS facilitates user interaction, file management, and multitasking capabilities, allowing multiple applications to run simultaneously.

CPU Purpose

The CPU functions as the main processing unit of a computer, performing calculations, executing instructions, and managing data flow within the system.
It consists of various components, including the arithmetic logic unit (ALU) and control unit (CU), which work together to perform tasks.

Volatile Memory

Volatile memory, such as Random Access Memory (RAM), loses its data when the power is turned off, making it temporary storage for current operations and processes.
This type of memory is essential for active tasks but does not retain information after shutdown.

Input Device Function

An input device allows users to enter data and commands into a computer system, facilitating user interaction with the machine.
Examples include keyboards, mice, scanners, and microphones, each serving specific functions to capture user input.
