This article will explain in detail to you about the current use of the computer word length is generally several, the editor thinks it is very practical, so share with you as a reference, I hope you can get something after reading this article.

The word lengths of computers used today are both 32 and 64 bits. If the word length of a computer is 32 bits, it shows that the binary data that the computer can process as a whole in CPU is 4 bytes; if the word length of the computer is 64 bits, CPU can process 8 bytes of binary data at the same time.

The word lengths of computers used today are both 32 and 64 bits.

The computer uses binary coding to represent numbers, characters, instructions and other control information. When a computer is stored, transmitted, or operated, a set of binary codes as a unit is called a word, and the number of bits in a word is called a word length.

A CPU that handles 8-bit data is usually called an 8-bit CPU,32-bit CPU, which processes 32-bit binary data at the same time. Each 0 or 1 of the binary is the smallest unit that makes up the binary, called a bit. The commonly used word lengths are 8 bits, 16 bits, 32 bits, and 64 bits. A code with a word length of 8 bits is called a byte and is the basic coding unit in a computer.

The word length has a great relationship with the function and use of the computer, and it is an important technical index of the computer. Word length directly reflects the calculation accuracy of a computer. in order to meet different requirements and coordinate the relationship between operation accuracy and hardware cost, most computers support variable word length operation. that is, half-word-length, full-word-length (or single-word-length) and double word-length operations can be realized in the machine. Other indicators are the same, the larger the word length, the faster the computer can process the data.

The word length of early microcomputers was generally 8-bit and 16-bit, while 386 and higher processors were mostly 32-bit. Most of the computers on the market have 64-bit processors, while a few are 32-bit. The word length is determined by the total number of data lines of the external data path of the microprocessor.

This is the end of this article on "the word length of computers currently in use is usually several". I hope the above content can be of some help to you, so that you can learn more knowledge. if you think the article is good, please share it for more people to see.
