I/O is the abbreviation of input/output, that is, input and output port. It is also called a port connector. Generally speaking, each device will have a dedicated I/O address to process its own input and output information.
The function of the I/O connector is responsible for realizing that the CPU connects the I/O circuit and peripheral devices through the system bus. According to the complexity of the circuit and the device, the hardware of the I/O interface is mainly divided into two categories:
(1) I/O interface chip. These chips are mostly integrated circuits, which input different commands and parameters through the CPU, and control related I/O circuits and simple peripherals for corresponding operations. Common interface chips such as timer counters, interrupt controllers, DMA controllers, Parallel interface, etc.
(2) I/O interface control card. It is composed of a number of integrated circuits according to a certain logic as a component, or it is directly on the motherboard with the CPU, or a plug-in is inserted into the system bus slot.
According to the connection object of the interface, they can be divided into serial interface, parallel interface, keyboard interface and disk interface.
