WHAT ARE BITS AND BYTES?
A "bit" is the smallest unit of information that can be stored in a computer, and consists of either a 1 or 0. All computer calculations are in bits.
A "byte" is a collection of 8 bits. they can represent 256 characters, such as numbers or letters. So a byte is 8 times larger than a bit.
The progression is as follows:
Bit (b) 1 or 0
Byte (B) 8 bits
Kilobyte (KB) 1,000 bytes
Megabyte (MB) 1,000 KB
Gigabyte (GB) 1,000 MB
Terabyte (TB) 1,000, GB
Petabyte (PB) 1,000 TB
Exabyte (EB) 1,000 PB
Zettabyte (ZB) 1,000 EB
