This article mainly introduces that the word length of a computer depends on the width of what bus? Has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand.

The word length of the computer depends on the width of the "data bus". The word length of a computer refers to the number of binary digits used to perform an operation, which can be divided into 8, 16, 32 and 64 bits, which mainly depends on the width of the data bus. The width of the data bus is an important index that determines the performance of the computer. The data bus of the computer is mostly 32-bit or 64-bit.

Computer word length refers to the number of binary bits used to perform operations, which can be divided into 8, 16, 32 and 64 bits, which mainly depends on the width of the data bus; for example, Pentium is 32 bits, which means that the registers of the processor can hold 32 bits of data.

Bus (Bus) refers to the standardized exchange of data (data) between computer components, that is, to provide data transmission and control logic for each component in a general way.

From another point of view, if the motherboard (Mother Board) is a city, then the bus is like a bus (bus) in the city, which can transmit bits (bit) running back and forth in accordance with a fixed route. These lines can only transmit one bit at a time.

Therefore, it is necessary to use multiple lines at the same time to send more data, and the number of data that the bus can transmit at the same time is called width, in bits, the larger the bus width, the better the transmission performance. The bus bandwidth (that is, the total number of data that can be transmitted per unit time) is: bus bandwidth = frequency × width (Bytes/sec).

Data bus (DataBus) standardizes the implementation method of data sharing and exchange between isomorphic and heterogeneous systems in a large integrated application system, and the standard of data exchange between systems. It can be used to transfer information between microprocessor and memory, microprocessor and input / output interface. The width of data bus is an important index to determine the performance of computer. The data buses of microcomputers are mostly 32-bit or 64-bit.

Thank you for reading this article carefully. I hope the editor shares the question "the word length of a computer depends on the width of what bus?" This article is helpful to everyone. At the same time, I hope you will support us and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
