Bits & Bytes


BIT
A binary digit is called a bit. Usually expressed as 0 and 1 the two numbers of the binary numbering system. A bit is the smallest unit of information a computer can use. A 16 bit computer would process a series of 16 bits,such as 0100111101011000 in one go, repeating the process thousands or millions of times per second.

BYTE
A group of 8 bits are in a byte. With 8 bits ( binary digits ), there exists 256 possible denary combinations. If you remember that 1 byte can store one alphabetical letter, single digit, or a single character/symbol, such as #. Large numbers of bytes can be expressed by kilobyte and megabyte.

Bits are binary digits. A bit can hold the value 0 or 1.
Bytes are made up of 8 bits each.


Byte: Single unit of data.

Kilobyte (KB): 1000 bytes.

Megabyte (MB): 1000 KB

Gigabyte (GB or Gig): 1000 MB

Terabyte (TB): 1000 GB

Petabyte (PB): computer storage equal to one quadrillion bytes.

Exabyte (EB): computer storage equal to one quintillion bytes.

Zettabyte (ZB): computer storage equal to one sextillion (one long scale trilliard) bytes.

Yottabyte (YB): computer storage equal to one septillion (one long scale quadrillion) bytes.
