Yadu computer internals final 1
A computer is a device that computes or calculates. It is made up of both hardware and software. The hardware are the physical parts like the keyboard, monitor, etc. The software are programs and instructions. The main hardware component is the system unit, which contains the central processing unit (CPU) that performs calculations, memory to store data and instructions, and various storage devices like the hard disk and CD-ROM. The computer requires data and instructions as input, processes them, and provides output.
Hardware- the entire parts of a computer
This document defines and describes various computer hardware components. It begins by defining computer hardware as the physical parts of a computer system, including the processor, memory, buses, and peripherals. It then lists and describes both essential internal components like the CPU, motherboard, memory, and hard disk, as well as optional external components like the keyboard, monitor, mouse, printers, and scanners. For each component, it provides details on what it is, its purpose, and common types. The document aims to provide a comprehensive overview of the main hardware that makes up a computer system.
Lecture 1.pdf
