8 Bit = 1 Byte.
1,024 Bytes = 1 Kilobyte.
1,024 Kilobyte (1,048,576 Bytes) = 1 Megabyte.
1,024 Megabyte (1,073,741,824 Bytes) = 1 Gigabyte.
1,024 Gigabyte (1,099,511,627,776 Bytes)= 1 Terabyte.

Bit

• a "bit" the smallest unit of storage
• A bit stores just a 0 or 1
• Group 8 bits together to make 1 byte

Byte

• One byte = grouping of 8 bits (e.g. 0 1 0 1 1 0 1 0)
• One byte can store one character, e.g. 'A' or 'x' or '\$' etc...

Kilobyte

• As a measure of computer memory or storage, a kilobyte (KB or Kbyte) is approximately a thousand bytes (actually, 2 to the 10th power, or decimal 1,024 bytes).
• In decimal systems, kilo stands for 1,000, but in binary systems, a kilo is 1,024 (2 to the 10th power). Technically, therefore, a kilobyte is 1,024 bytes.

Megabyte

• A unit of computer memory or data storage capacity equal to 1,024 kilobytes is called Megabyte.
• A megabyte is 2 to the 20th power (approximately 1 million)

Gigabyte

• A gigabyte (GB) is a measure of computer data storage capacity that is roughly equivalent to 1 billion bytes.
• A gigabyte is two to the 30th power or (approximately 1 billion).

Terabyte

• A terabyte (TB) is a measure of computer storage capacity that is 2 to the 40th power, or approximately a trillion bytes.
• A terabyte is more precisely defined as 1,024 gigabytes (GB)
