Components of Computer
Motherboards connect the various components of a computer system and determine the computer's capabilities. They come in different form factors and have varying components depending on the intended use of the system. Faster motherboards support higher CPU speeds and more memory through wider data buses that transfer information between components. Buses, sockets, and adapter cards are key components that expand the motherboard's capabilities by allowing additional devices to connect and communicate with the CPU and other parts. Common adapter cards include video graphics cards, sound cards, and network interface cards. User interfaces also connect through the motherboard and can be command-line based or graphical user interfaces using icons, windows, and a mouse.

The CPU is the most important component as it executes instructions, performs calculations, and controls input/output devices. The CPU undergoes a cycle of fetching instructions from memory, decoding them, and then executing them. Memory stores all data and instructions and comes in different types, including RAM (static and dynamic) and ROM.
Basic of operating system
This document provides an overview of the basic components and operations of a computer system. It discusses how a computer system is composed of input, output, processing, memory, and controlling units. The central processing unit (CPU) acts as the brain and contains the arithmetic logic unit (ALU) and control unit to process data. Memory, including primary memory like RAM and ROM, is used to store programs and data both temporarily for processing and more permanently. Input and output devices allow the user to interface with the computer system by entering and receiving data. The five basic operations of a computer system are inputting, storing, processing, outputting, and controlling data.
