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
