Computer information is expressed in binary, then the amount of binary information to reflect these are, bit, word, byte, word and other indicators.
(1) bit or bits (bit).
Storing information on the computer by a plurality of electronic circuit units, each unit is called a "bit" ( 'bit), which has two stable working condition, respectively, "0" and "1". It is the smallest unit of data in the computer.
(2) bytes (byte).
In the computer, a 8-bit binary numbers are called "bytes" (byte, short B), constituting a byte of eight bits is treated as a whole. It is the basic unit of computer storage of information, but it is also the most basic of computer storage space capacity units. Byte is a measure of computer storage of binary information units, it has kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB).
= 2 1024B = 1KB 10 B
1MB=1024KB=220B
1GB=1024MB=230B
1TB=1024GB=240B

(3) word (word).
Several bytes of a "word" (word). A "word" can be stored in a computer instruction or a data.
(4) word length.
Each CPU may include the binary word length is called "word length" (word size). It is stored in the computer, the unit of information transfer, data processing, is one measure of the accuracy of comparison computer function key performance indicators and speed of operation. The longer the word length, the more information can be transmitted in the same time, so that the faster computing speed, the higher the accuracy, the larger address space, the larger the memory capacity, the more abundant the number of instructions supported by the computer system. Low microcomputer word length of 8 bits (one byte), high-end computer word length is 16 bits (two bytes), 32 bits (four bytes) and the like.
