Computer Fundamentals and MS Office Introduction Basics of computer hardware and software 1. Computer Hardware: Hardware refers to the physical components of a computer system. It includes everything you can physically touch and interact with. Here are the basic components: Central Processing Unit (CPU): The "brain" of the computer, responsible for executing instructions and performing calculations. It contains the Arithmetic Logic Unit (ALU), Control Unit (CU), and Registers. Motherboard: The main circuit board that connects all the components of the computer, including the CPU, RAM, storage devices, and peripheral devices. Memory (RAM): Random Access Memory (RAM) is the temporary memory used by the CPU to store data and instructions that are actively in use. It is volatile, meaning it loses all data when the power is turned off. Storage Devices: Hard Disk Drive (HDD): A traditional storage device that uses mechanical components to read and write data. Solid State Drive (SSD): A faster, more durable storage device that uses flash memory instead of mechanical parts. Input Devices: These devices allow users to interact with the computer. Examples include the keyboard, mouse, scanner, and microphone. Output Devices: These devices display or provide the result of the computer’s processing. Examples include monitors,
