The smallest unit of measurement is used for measuring information is a bit. A single bit can have a value of either 0 or 1. It might contain a binary value, (for example, On/Off or True/False), however nothing more. In this way, a byte, or eight bits, is utilized as the basic unit of measurement for information. A byte can store 28 or 256 distinct values, which is sufficient to represent standard ASCII characters, for example, letters, numbers and symbols.
Since most documents contain a huge number of bytes, record sizes are regularly measured in kilobytes. Bigger records, for example, pictures, recordings, and sound documents, contain a great many bytes and in this way are measured in megabytes. Current stockpiling gadgets can store a huge number of these documents, which is the reason stockpiling limit is regularly measured in gigabytes or even terabytes. Bigger units of estimation are normally held for measuring the whole of different stockpiling gadgets or the limit of vast information stockpiling systems.
The following is a rundown of all the standard units of estimation utilized for information stockpiling, from the littlest to the biggest.
Note : Lower case (b) is used for bits and the upper case (B) is used for Byte.

Below is a list of all the standard units of measurement used for data storage, from the smallest to the largest.
| Unit | Value | Size |
|---|---|---|
| bit (b) | 0 or 1 | 1/8 of a byte |
| byte (B) | 8 bits | 1 byte |
| kilobyte (KB) | 10001 bytes | 1,000 bytes |
| megabyte (MB) | 10002 bytes | 1,000,000 bytes |
| gigabyte (GB) | 10003 bytes | 1,000,000,000 bytes |
| terabyte (TB) | 10004 bytes | 1,000,000,000,000 bytes |
| petabyte (PB) | 10005 bytes | 1,000,000,000,000,000 bytes |
| exabyte (EB) | 10006 bytes | 1,000,000,000,000,000,000 bytes |
| zettabyte (ZB) | 10007 bytes | 1,000,000,000,000,000,000,000 bytes |
| yottabyte (YB) | 10008 bytes | 1,000,000,000,000,000,000,000,000 bytes |
