Binary Number System

The Binary Number System
The binary (the prefix bi meaning two) number system uses only the two value: 0 and 1. This matches the capabilities of the transistor perfectly, as the transistor can also have only two states or values. The bonding of these two states allows the computer to use the binary number system. The computer stores a single binary number (either a one or a zero) in a single transistor. In fact, the word bit in computer language is a short form of binary digit. Each transistor holds a single electrical charge that is either positive or non-positive, which is turn represents a 1 or a 0.

Bit
A bit is a binary digit, taking a value of either 0 or 1. for example, the number 10010111 is 8 bits ling. Binary digits are a basic unit of information storage and communication in digital computing and digital information theory.

Byte
Eight bits are grouped together to form what is called a byte. AS byte can store smaller integer numbers or a single character. The eight bits of a byte can create 255 different values in the binary number system.

Kilobytes
A kilobyte (derived from the kilo-, meaning 1,000) is a unit of information or computer storage equal to 1,024 bytes (210). It is commonly abbreviated KB.

Megabytes
a megabyte is a unit of information or computer storage equal to 1,048,576 bytes ie 1024 kilobytes. It is commonly abbreviated as MB.

Gigabytes
A gigabyte is a unit of information or computer storage equal to 1024 megabytes. It is commonly abbreviated as GB.
