This article mainly introduces the use of the data bus in the computer, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, let the editor take you to understand it.

If the instructions in memory are sent to cpu for processing, it is done through the "data bus". The bus is the common communication trunk that transmits information between various functional components of the computer, while the data bus transmits the data that needs to be processed or stored back and forth between CPU and RAM.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

If the instructions in memory are sent to cpu for processing, it is done through the "data bus".

Bus is a common communication trunk that transmits information between various functional components of a computer. It is a transmission harness composed of wires. According to the types of information transmitted by the computer, the computer bus can be divided into data bus, address bus and control bus, which are used to transmit data, data address and control signals respectively. Bus is a kind of internal structure, which is a common channel for cpu, memory, input and output devices to transmit information. each part of the host computer is connected by the bus, and the external equipment is connected with the bus through the corresponding interface circuit, thus forming the computer hardware system. In a computer system, the common path through which information is transmitted between various components is called a bus, and a microcomputer connects each functional component with a bus structure.

Data bus (Data Bus): transfers data that needs to be processed or stored back and forth between CPU and RAM.

Address bus (Address Bus): used to specify the address of data stored in RAM (Random Access Memory).

Control bus (Control Bus): transmits the signal of the microprocessor control unit (Control Unit) to the peripheral device.

Data bus (DataBus)

Standardize the implementation method of data sharing and exchange between isomorphic systems 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.

1. Business entity data exchange: each subsystem has a business entity layer in the architecture layer, and the data exchange mechanism establishes a layer transparent to all application systems in the business entity layer. No matter what the specific technical scheme is, the subsystems can share and interact through the business entity layer, which establishes a structure that can carry out continuous integration and business expansion among subsystems. in order to achieve a scalable and complete integrated information system.

2.WebService data exchange is a Web service standard. Web service provides a solution for sharing and exchanging data among heterogeneous systems. It can also be used for data sharing and exchange using a unified interface standard in product integration.

Thank you for reading this article carefully. I hope the article "what is the use of data bus in computer" shared by the editor will be helpful to everyone? at the same time, I also hope that you will support and pay attention to the industry information channel. more related knowledge is waiting for you to learn!
