  # Byte Chart - Jargon

Abbreviations like Kb, KB, Mb and GB are often confused, misunderstood or used incorrectly. Here is a brief explanation of proper usage.

The only data that a computer can understand is on and off. But those two simple commands can be grouped into millions of combinations and it is the way they are grouped in series that creates complex data.

The basic unit is called a bit (binary digit). Each bit has an electronic switch, or gate. If the gate is open the bit is on and electricity can go through. The computer reads on or open switches as a number 1. If the gate is closed or off, the electricity is blocked and the computer reads off bits as 0.

Bits can be grouped together to allow more complex code. Eight bits are grouped together to form a byte. This allows 256 possible combinations of 1/0. The abbreviation for bit is a lowercase "b"; the abbreviation for byte is an uppercase "B". Bits and bytes can then be expressed in larger measurements. They are generally expressed in exponents of two, known as binary code.

 TidBits about Bits - Bytes - Nibbles and the "Power of Twos" The text of a thirty volume Encyclopedia would use about 1GB ASCII Storage. The width of a "Word" is only generally 32 bits (depending on hardware) b Bit 20 Two to the 0 power = 1 (true) or 0 (false) Nibble 22 Two to the 2 power  = 4 bits B Byte 23 Two to the 3 power = 8 bits = 1Byte Wyde or Halfword 24 Two to the 4 power = 16 Bits Word 25 Two to the 5 power = 32 Bits Double or Double Word 26 Two to the 6 power = 64 Bits Quad or Quad Word 27 Two to the 7 power = 128 Bits Kb Kilobit 210 Two to the 10th power = 1024 bits = 1.024Kb KB Kilobyte 210 Two to the 10th power = 1024 Bytes = 1.024KB MB Megabyte - Megs 220 Two to the 20th power = 1,024 KB = 1,048,576 B GB Gigabyte - Gigs 230 Two to the 30th power  = 1,024 MB = 1,048,576 KB TB Terabyte 240 Two to the 40th power  = 1,024 GB = 1,048,576 MB PB Petabyte 250 Two to the 50th power  = 1,024 TB = 1,048,576 GB EB Exabyte 260 Two to the 60th power = 1,024 PB = 1,048,576 TB ZB Zettabyte 270 Two to the 70th power  = 1,024 EB = 1,048,576 PB YB Yottabyte 280 Two to the 80th power  = 1,024 ZB = 1,048,576 EB NB Nonabyte? 290 Two to the 90th power  = 1,024 YB = 1,048,576 ZB DB Doggabyte? 2100 Two to the 100th power  = 1,024 NB = 1,048,576 YB Did we miss one?Please use our acronym submit form to suggest additions, corrections or make comments.
