The editor would like to share with you what the iCompo interface means. I hope you will get something after reading this article. Let's discuss it together.

The full name of the Input/Ouput interface is the input / output interface, which is the connection circuit for exchanging information between the CPU and external devices, which are connected to the CPU through the bus. The iMacro interface can be divided into two types: bus interface and communication interface.

Computer I / O interface is the connection circuit for exchanging information between CPU and external devices. They are connected with CPU through bus, which is referred to as Input/Ouput interface. Icano interface is divided into two types: bus interface and communication interface.

The computer I / O interface is used for data, information exchange and control between the external equipment or user circuit and the CPU. When in use, the microcomputer bus should be used to connect the external equipment and the user circuit, so it is necessary to use the microcomputer bus interface. When the microcomputer system communicates directly with other systems, the communication interface is used.

The so-called bus interface is a kind of bus socket which provides the microcomputer bus to the user through the circuit socket for inserting various function cards. Each pin of the socket is connected with the corresponding signal line of the microcomputer bus. As long as the user makes the wiring board of the external equipment or user circuit according to the order of the bus arrangement, the connection between the external device or user circuit and the system bus can be realized. Make the external equipment or user circuit integrated with the microcomputer system.

The commonly used bus interfaces are AT bus interface, PCI bus interface, IDE bus interface and so on.

AT bus interface is mostly used to connect external devices in 16-bit microcomputer system, such as 16-bit sound card, low-speed display adapter, 16-bit data acquisition card, network card and so on.

PCI bus interface is used to connect external devices in 32-bit microcomputer system, such as 3D display card, high-speed data acquisition card and so on.

The IDE bus interface is mainly used to connect various disks and CD-ROM drives, which can improve the data exchange speed and ability of the system.

Communication interface refers to the interface circuit of direct digital communication between microcomputer system and other systems, which is usually divided into serial communication interface and parallel communication interface, namely serial port and parallel port.

The serial port is used to connect low-speed external devices such as the MODEM to a microcomputer and transmit information bit by bit. The standard of serial port is EIA (Electronics Industry Association, Electronic Industry Association) RS-232C standard. The serial connectors include D-type 9-pin socket and D-type 25-pin socket, which are located on the back panel of the main chassis of the computer. The mouse is connected to this serial port.

The parallel interface is mostly used to connect high-speed external devices such as printers, and the way of transmitting information is carried out in bytes, that is, 8 binary bits at the same time. The parallel port used in PC is the standard parallel port Centronics. The printer generally uses the parallel port to communicate with the computer, and the parallel port is also located on the back panel of the computer main chassis.

They are usually called adapter cards, such as floppy drive adapter card, hard disk drive adapter card (IDE interface), parallel printer adapter card (parallel port), serial communication adapter card (serial port), display interface, audio interface, network card interface (RJ45 interface), telephone interface used by modem (RJ11 interface), etc.

In microcomputer systems above 386, these adapter cards are usually made on a circuit board, which is called composite adapter card or multi-function card for short.

After reading this article, I believe you have a certain understanding of "what is the meaning of the iCompo interface". If you want to know more about it, you are welcome to follow the industry information channel. Thank you for reading!
