Study Notes

Computer Basics

A computer is a machine that changes information from one form to another through input, processing, output, and storage.
Computers take raw data and transform it into organized information.
Two types of computers exist: analog and digital. Analog computers measure data on a scale with many values; digital computers use data in digital or numerical form with fixed values.

Information Processing Cycle

Input: The raw information or data entered into a computer. This can range from simple letters and numbers to complex images. Input devices include keyboards, mice, scanners, cameras, and microphones.
Bits of data are entered into a computer using a coded language, with each bit having two possible values: 0 or 1. Off state = 0, On state = 1.
Processing: The computer carries out a task using instructions or programs written in binary code. These instructions tell the computer what to do. The speed of processing is very rapid, with computers performing millions of operations every second. Examples of processing include arithmetic and logic operations.
Output: The result of the computer's processing is presented to the user in various forms such as displaying images on a screen, producing sounds through speakers, or generating printed documents.
Storage: The action of saving information within the computer system(RAM - storage during operation; Secondary storage like hard drives / SSDs - storage even when off ). If storage isn't used, all work is lost. Primary storage is for instructions/data needed while operating a computer.
