meaning of different memories

BIT: a bit is short for binary digit and is the smallest data in a computer. a bit has a single binary value, either 0 or 1.

Mb: MB is short for megabit, this is mainly used for download speed.

MB: MB, meg or mbit is a common measurement used with computer storage media, a

megabyte is equal to 1,048,576 bytes.

KB: KB short for kilobytes are most often used for small sized files.

GB: A GB is short for gigabyte and is a measure of computer data storage capacity and is roughly a billion bytes.

TB: Terabytes are most often used to measure the storage capacity of large storage devices.

Bytes: The byte is a unit of digital information in computing and telecommunications that most commonly consists of eight bits.

1 bit (a 0 or 1 binary digit)

A bit is the smallest amount that a computer can store (using ON or OFF in a circuit).

1 nibble = 4 bits

1 byte = 8 bits (an ASCII character takes 1 byte.)

So 1 byte = 2 nibbles!

1 kilobyte = 1024 bytes

1 megabyte = 1024 kilobytes           (or 1024 x 1024 bytes)

1 gigabyte = 1024 megabytes           (or 1024 x 1024 kilobytes)

1 terabyte = 1024 gigabytes
