The relationship between byte, Word, bit, byte, byte is distinguished

1, bit (bit)

From the English bit, transliteration is "bit", indicating bits. Bits are the smallest unit of data storage within the computer, and 11010100 is a 8-bit binary number. A bits can only represent 0 and 12 states; Two bits can represent 00, 01, 10, 114 states; The three-bit binary can represent eight states.


2, Bytes (byte)
From English byte, it is customary to use uppercase B to denote. Byte is actually the same as byte, except that in C + +, Byte is represented as a class
Bytes are the basic unit of data processing in a computer. The computer stores and interprets information in byte-bit units, which specifies that a byte consists of eight bits, that is, one byte equals 8 bits. The minimum eight-bit binary number is 00000000 and the maximum is 11111111; usually one byte can be stored in an ASCII code, and 2 bytes can hold a Chinese character GB code.


3, Word (2 bytes)

When a computer is processing data, the length of time it accesses, processes, and transmits is called word. A word is usually made up of one or more bytes (usually the integer bits of bytes). For example, 286 microcomputer consists of 2 bytes, its word length of 16;486 microcomputer is composed of four bytes of words, it is a 32-bit length machine.
The word length of the computer determines the actual number of bits that the CPU handles at a time, thus the larger the computer's character, the better its performance.


Another way of saying:

Word

In a computer, a string of digital as a whole to process or operate, called a computer word, abbreviated word. The word is usually divided into several bytes (each byte is typically 8 bits). In memory, it is common for each cell to store one word, so each word is addressable. The length of the word is represented by the number of digits.


In computer operators, controllers, usually in the word for transmission. Words appear at different addresses whose meanings are different. For example, the word sent to the control area is an instruction, and the word sent to the operator is a number.
The binary number string that is accessed, transmitted, and processed as a whole in a computer is called a word or unit, and the length of the number of bits in each word is called words. A word consists of a number of bytes, different computer systems, the length is different, the common 8-bit, 16-bit, 64-bit, and so on, the longer the length of a computer, the more information bits, the higher the accuracy, the word length is an important indicator of computer performance. At present, the mainstream microcomputer is 32-bit machine.

Word Length (the number of bits of the operating system, such as 32-bit operating systems, that each processing 32 bits is 32/8=4 bytes, i.e. 4 bytes per processing)

The number of bits that each word of the computer contains is referred to as the length. Depending on the computer, there are two types of word length that are fixed and variable. Fixed word length, that is, no matter what the case is fixed constant, variable length, in a certain range, its size is variable.
The word length of a computer is the number of binary digits that it can handle at one time. The rate at which a computer processes data is naturally related to the number of bits it can process at a time and the speed of its operation. If the word length of a computer is twice times that of another computer, even if the two computers are the same speed, the former can do twice times the latter in the same time.
In general, the word length of the mainframe computer is 32-64 bits, the small machine bit 12-32 bits, and the microcomputer bit 4-16 bits. Word length is an important factor in the performance of line two computers.


Bytes

Byte refers to a small group of contiguous binary digital. is usually 8 bits as a byte. It is a small unit of information, and as a whole to participate in operations, smaller than words, is the unit of the constituent words. In a microcomputer, how many bytes are usually used to represent memory storage.

Word block
In information processing, a group of words as a unit to deal with is called "word block", also known as "Word Group". For example, a group of characters stored on a track in drum is called a block of characters. A block flag is usually spaced every 120 characters on a tape, and also becomes a block of text. Between block and block generally leave 1.27-2.54 cm interval. In bulk storage, information is stored in chunks, so only chunks are available for selection. At present, the concept of "word block" is also introduced in the high-speed buffering technology.

Conversion:

1 Byte = 8 Bits

1 KB = 1024x768 Bytes

1 MB = 1024x768

1 GB = 1024x768
