Question

What is byte and bits

Answer 1

a group of binary digits or bits (usually eight) operated on as a unit is called byte

A bit (short for binary digit) is the smallest unit of data in a computer. ... Although computers usually provide instructions that can test and manipulate bits, they generally are designed to store data and execute instructions in bitmultiples called bytes. In most computer systems, there are eight bits in a byte.

Answer 2

Hey
Here's your answer !!

Computer can understand only binary language , that is , it can only understand 0 and 1 .

0 for false and 1 for true .
Or 0 for on and 1 for off.

Anything that you write on a computer is called a high level language ( HLL ) . This high level language is converted into machine level language ( MLL ) , i.e., 0 and 1 with the help of a compiler ( generally preferred ) or an interpreter.

Now ,
these 0s and 1s have to occupy some space in the computer memory .
Each 0 or 1 occupy a very small amount of space known as bit .
One 0 or one 1 will occupy 1 bit.

8 bits sum up to form 1 byte .

Now ,
4 bits = 1 nibble
1024 byte = 1 KB ( kilobyte )
1024 KB = 1 MB ( megabyte )
1024 MB = 1 GB( gigabyte )
1024 GB = 1 TB ( terabyte )
1024 TB = 1 PB ( petabyte )
1024 PB = 1 EB ( exabyte )
1024 EB = 1 ZB ( zettabyte )
1024 ZB = 1 YB( yottabyte )

Hope it helps !!
