So, in computer terms:1 kilobyte (KB) = 1024 bytes
1 megabyte (MB) = 1,048,576 bytes
1 gigabyte (GB) = 1,073,741,824 bytes
What is a bit?A bit is a binary digit, the smallest increment of data on a machine. A bit can hold only one of two values: 0 or 1.Because bits are so small, you rarely work with information one bit at a time.
Bits are usually assembled into a group of 8 to form a byte. A byte contains enough information to store a character, like "h".
What is a byte?Byte is an abbreviation for "binary term". A single byte is composed of 8 consecutive bits capable of storing a single character.
