The Computer works with binary numbers. Binary means two. Binary numbers consists of only two digits. These 0 and 1. Each number is represent a pulse inside computer. 1 is represent by a pulse of electricity and 0 by an absence of a pulse. Each binary digit is called a bit. A bit is short for binary integer.
A combination of 4 bits is called nibble.
According to Sir Faheem Abbas:
A bit is consist on two nibs.
2 nibs =1 bit
8 bits = 1 byte
1024 bytes = 1 kilo bytes
1024 kilo bytes = 1 mega byte
1024 mega bytes = 1 gaga byte
1024 gaga byte =1 Tera byte
1024 tera byte = 1 peta byte
1024 peta byte = 1 Exa byte
