Requirement of Binary Number System

In Processor

  • Computers use the binary number system.(0s and 1s) to store data.

  • Binary (or bit) is the smallest unit of data in computing.

Microprocessor deals with 0s and 1s.

(binary codes that activate the CPU.)

  • The circuits in a computer's processor are made up of billions of transistors.

  • A transistor is a tiny switch that is activated by the electronic signals it receives.

  • The digits 1 and 0 used in binary reflect the on and off states of a transistor.

ICs in motherboard have a billion transistors.

Transistor is activated by electronics signal ie. 1s and 0s

In Storage Medium

  • The binary system used to store the data in different storage media.

All the storage media store stream of bits either 0s or 1s.

Optical disk

Hard Drive disc

Flash drive

In File Format

  • Everything on a computer is represented as streams of binary numbers.

  • Audio, images, and characters all look like binary numbers in machine code.

  • Encoding formats have been standardized to help compatibility across different platforms.

The binary is encoded to different file format to give them meaning.

Audio is encoded into file format:

eg. mp3, WAV, AAC

Video is encoded into:

eg. mpeg4, 3gp,

Image is encoded into:

eg. JPEG, PNG, BMP

In Display

  • Used in the modern display to demonstrate the picture.

  • RGB pattern receives signal of different binary value for correspondence color intensity to make a picture.

  • This larger number of combinations can be used to represent many more things.

Input and output devices work with the binary number system.

Keyboard

Monitor
