Computer Memory Unit

A computer memory unit is used to measure the amount of data that can be store in a storage unit. A group of binary digits that is 0's and 1's is used to store and process the data because the computer only understands the machine language or binary language.

Types of a Memory storage unit

The memory units of the data in the storage systems are classified into the below different types

Bit: 

A bit stands for binary digit. A bit is a one or a zero, on or off, which is how all computer information is stored. A bit is the smallest memory unit to measure data stored in main memory and storage devices.

Nibble: 

Nibble can be defined as the collection of four bits. It is sometimes called Nybble’ or ‘Nyble’ or ‘hex digit’.

Byte:

It is the fundamental unit to measure data. A group of 8 bits is called byte. Thus a byte can represent 2*8 or 256 values. This storage capacity is expressed in terms of Bytes. This is the commonly used unit terminology, as it comes with the prefixes for the multiples of bytes, such as the prefixes as kilo-, mega-, giga-, tera-, peta-, etc.

Word:

Word is a group of fixed numbers of bits processed as a unit, which varies from computer to computer but is fixed for each computer. The length of a computer word is called word-size or word length. It may be as small as 8 bits or maybe as long as 96 bits. A computer stores the information in the form of computer words.

A bit is the smallest unit and Geopbyte is the highest memory unit.
