Hello friends, in today’s article we are going to talk about memory units.
Today we will learn in detail about what is memory units. And what is its use? So without any time let’s first understand what is memory units.
What are Memory Units?
Just as we have seconds, minutes, and hours to measure time, there are units like inches, centimeters, meters, and feet to measure any length and there are liters to measure water, in the same way in the computer world, To measure the storage capacity of computer memory we have memory units.
Memory units are used to describe the size of data files stored in computer memory. We use it to tell how much space a particular file will occupy in memory.
Let’s understand some such memory units which are commonly used to measure and represent data.
12 Basic Memory Unit in Computer
Memory units start with a bit. Bit is the smallest unit used to measure data in a computer. 1 bit contains either 0 or 1. 0 represents no electronic signal in memory and 1 represents is signal.
All the computers in this world understand the language of 0 and 1, so whatever instruction we have to give to the computer is in the form of 0 and 1.
This is a collection of 4 bits which is sometimes also called ‘Nybble’ or ‘Nyble’.
A group of 8 bits is called a byte, it is the smallest unit used to represent any data in a computer.
Like a byte, Word is also a group of some fixed size bits. This is another basic memory unit of the computer system.
The number of words depends on different computer systems. The number of bits in a word can range from 8 bits to 96 bits.
A Kilobyte is a collection of many bytes or you can say that a Kilobyte is made up of many bytes. There are 1024 bytes or binary digits in a kilobyte.
A Megabyte is made up of many Kilobytes. There are 1024 Kilobytes in a Megabyte.
A Gigabyte (GB) is made up of several Megabytes (MB). There are 1024 Megabytes (MB) in a Gigabyte.
A Terabyte is made up of several Gigabytes (GB). There are 1024 Gigabytes (GB) in a Terabyte.
There are 1024 Terabytes (TB) in a Petabyte.
There are 1024 Petabytes (PB) in one Exabyte.
There are 1024 Exabytes (EB) in a Zettabyte.
There are 1024 Zettabytes (ZB) in a Yottabyte.
