What Is Bit (Computing)? – POFTUT

# What Is Bit (Computing)?

A `bit` is the smallest data storage and unit of measurement in computing. A bit can hold only one of the two data 0 or 1. The bit is used also to specify the size of the RAM, GPU, CPU architecture, HDD size, variable sizes in programming, etc.

## Bit Stores Binary Data

A bit is the simples storage unit for data. Binary data can be stored in a bit where binary values consist of 0 and 1. It may seem so simple which is not useful but it works. Every data in a traditional computer system is stored in bits with 0’s and 1’s.

## Bit May Store True and False

The stored values of the bit may have different meanings like `True` and `False`. As true and false are part of the logical values they can express as with 0 and 1.  Generally, 0 is used to express False and 1 is used to express True.

## 8 Bit is Equal To 1 Byte

As the bit is the smallest storage measurement unit there are other measurement limits bigger than a bit. 8 bit is equal 1 byte which is also a popular measurement unit in computing. There are also the following equations about a bit.

``````1 Nible = 4 Bit

1 Byte = 8 Bit

1 KiloByte = 8192 Bit

1 MegaByte = 8.388.608 Bit``````

## B or b or Byte or Bit

While using the bit as measurement units it can be expressed with some short-form like `b` in Mbps. But it can be confused with the Byte which is expressed as `B`. lower b is used express bit uppercase B is used to express Byte.

``````Mbps = Megabit per second

MBps = Megabyte per second

Gbps = Gigabit per second

GBps = Gigabyte per second``````
