Definition
The bus (Bus) is the connection between various functional components of the computer A public communication trunk that transmits information. It is a transmission harness composed of wires. According to the type of information transmitted by the computer, the computer bus can be divided into a data bus, an address bus and a control bus, which are used to transmit data, data addresses and control signals respectively. .
The bus is an internal structure. It is a common channel for CPU, memory, input and output devices to transmit information. The various components of the host are connected through the bus, and the external devices are connected to the bus through the corresponding interface circuits. , thus forming a computer hardware system.
In a computer system, the common channel for transmitting information between various components is called a bus. Microcomputers use a bus structure to connect various functional components.
Advantages of the bus structure:
(1) Low networking cost: This structure does not require additional interconnection equipment at all. It is connected directly through a bus, so the networking cost is low. ;
(2) Because each node of this kind of network shares the bus bandwidth, the transmission speed will decrease as the number of users accessing the network increases;
(3) Network User expansion is more flexible: when you need to expand users, you only need to add a connector, but the number of users that can be connected is limited;
(4) Maintenance is easier: the failure of a single node does not affect the normal communication of the entire network . But if the bus is broken, the entire network or the corresponding backbone network segment is broken.
