In a computer, all dataUnits of information. In computing there can be different data types, including integers, characters and Boolean. Data is often acted on by instructions. is stored in binaryA number system that contains two symbols, 0 and 1. Also known as base 2. form. A binary digitA single whole number value from 0 to 9, especially when used in a larger number. For example, the number 752 has 3 digits. has two possible states, 1 and 0.
A binary digit is known as a bitThe smallest unit of data in computing represented by a 1 in binary.. A bit is the smallest unit of data a computer can use. The binary unit system is used to describe bigger numbers too.
Eight bits are known as a byteA unit of data containing 8 bits..
The binary unit system is as follows:
8 bits
1 byte (B)
1,000 bytes (1,000 B)
1 kilobyte (KB)
1,000 kilobytes (1,000 KB)
1 megabyte (MB)
1,000 megabytes (1,000 MB)
1 gigabyte (GB)
1,000 gigabytes (1,000 GB)
1 terabyte (TB)
1,000 terabytes (1,000 TB)
1 petabyte (PB)

When calculating storage space for disk drives, it is common to use multiples of 1,000. These are shown in the table above as kilobytes, megabytes etc.
