All information is stored in a computer in binary code. Each character or symbol consists of a combination of 0's and 1's. For example, the letter "A" is stored as 01000001.
Definition:
A bit is a single Binary digIT, 0 or 1. It is the smallest unit of data that
a computer can process.
Explanation:
A bit gets its name from a combination of two words, Binary and digIT. A bit is either a 0 or a 1. A 0 is like an "off" switch for electronic impulses, and a 1 is like an "on" switch. A computer uses this to process all information. (8 Bits = 1 Byte)
Definition: A kilobyte is a unit of measurement for
memory and disk capacity. One K = 1,024 bytes.
Explanation: The prefix "Kilo" means thousand.
A kilobyte counts thousands of bytes.
Definition:
A megabyte is a unit of measure used to describe memory and disk capacity that
is equal to approximately 1 million bytes or 1,024 kilobytes.
Explanation: The prefix "Mega" means million. A megabyte counts millions of bytes.
Definition:
A gigabyte is a unit used for measuring a computer's memory or disk capacity.
It is equal to approximately one billion bytes or 1,024 megabytes.
Explanation: The prefix "giga"
means billion. Counting gigabytes can tell you how large your hard drive is
by counting billions of bytes.
