There are generally three types of buses in microcomputer systems. What are they?

The three buses in microcomputer systems are address bus, control bus and data bus; bus is an internal structure, which is a common channel for CPU, memory, input devices and output devices to transfer information.

Bus (Bus) is a public communication trunk for transmitting information between various functional components of the computer. It is a transmission composed of wires Wire harness, according to the type of information transmitted by the computer, the bus of the computer can be divided into data bus, address bus and control bus, which are used to transmit data, data address 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.

Bus can be divided into five types according to their functions and specifications:

Data Bus: Transmits data that needs to be processed or stored back and forth between the CPU and RAM.

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

Control Bus: Transmits signals from the microprocessor control unit (Control Unit) to peripheral devices.

Expansion Bus: A bus for data communication between external devices and the computer host, such as ISA bus and PCI bus.

Local Bus: An expansion bus that replaces higher-speed data transmission.
