Here's how to connect the following interfaces:
Usually, the wires in common cases include USB interface, audio interface and power-on and restart keys. The streets of these wires show functions, which are difficult for beginners to distinguish. For players who have installed computers, there are also familiar logos, which may be forgotten after long-term use. Let's introduce these interfaces first.
Power switch, power LED, reset switch, USB cable and high-definition audio are usually configured in the chassis. Power SW and reset SW are the most important connections, which are the switching and restarting of the indebted computer. Of course, if you use USB and audio interface in the I/O area of the front panel of the chassis, you need to connect USB and audio interface.
Often the wiring of the chassis will recognize their identities, because English abbreviations are alive, just like the models of monitors. Through this logo, players can easily distinguish it. It doesn't matter if you don't know the meaning of these letters, there are not many kinds of these connections.
The main switch, restart and LED lights are represented as power switch, reset switch, hard disk indicator light (H.D.D. LED) and power LED.
Look at it. Ask me if you don't understand.
Question 2: How to plug the cable correctly behind the computer host? There is nothing wrong with five points. White is the network cable, but USB to RJ45 is the network cable.
Unable to access the Internet. The USB network card driver may not be installed.
Question 3: How to plug the cable behind the computer host? For a slacker like you, I'm too lazy to type, just go to the picture!
Question 4: How to plug in the switch cable of the computer host? Look at the motherboard. Is it an on/off switch? It's the yellow and white needle you inserted in the upper right corner of the picture.
The following two are restart switches.
The host power switch is a switch. There is no difference between positive and negative.
RESET SW is a restart, and the positive and negative can be ignored.
Question 5: How to connect the computer chassis line with the corresponding letters in the picture? There is a sign next to the motherboard connector.
Question 6: How to insert the rear cable of the computer host into all the interface diagrams in the picture (insert the cable according to the shape):
DVI video transmission HDMI high-definition interface adapter, used for DVI video transmission HDMI high-definition interface.
DVI video adapter VGA video adapter for DVI video interface adapter VGA interface.
Sony/Philips Digital Interface Format
Spdif (digital audio output interface) is the abbreviation of Sony and Philips digital audio interface. SPDIF is divided into output (SPDIF output) and input (SPDIF input) interfaces. Most sound card chips can support SPDIF output, but not every sound card will provide a digital interface. However, there are few sound card chips supporting SPDIF IN, such as EMU 10K 1, YMF-744, FM80 1-AU, CMI8738, etc. The typical application of SPDIF in sound card is CD SPDIF, but not every sound card supporting SPDIF provides this interface. SPDIF can transmit signals through coaxial cable or optical fiber, and the signals they transmit are the same, but the appearance of interface and connecting cable is different. Optical fiber interface is more flexible and has stronger anti-interference ability than coaxial interface.
HDMI interface
Hdmi (high-definition multimedia interface) is a fully digital image/sound transmission interface, which can transmit uncompressed audio signals and video signals. HDMI can transmit audio and video signals at the same time. Because the audio and video signals use the same cable, the installation of the system is greatly simplified.
Digital display working group
Parallel port/interface
The parallel port adopts 25-pin double-row socket, which is widely used to connect printers, scanners, ZIP drives and even external network cards, tape drives and some extended hard disks.
Serial interface serial port
At present, the serial interface is directly integrated on the motherboard through a 9-pin connection. Generally speaking, a computer motherboard provides two serial interfaces.
Some old devices use serial interfaces. In addition, you can use Windows HyperTerminal to communicate with other devices through the serial port.
USB interface (universal serial bus interface)
USB interface is an interface standard jointly proposed by paq, IBM, Microsoft and other companies at the end of 1994, which is used to replace the traditional serial port and parallel port. At present, there are two USB interface standards, namely USB 1. 1 and USB 2.0. USB 2.0 is the latest USB device specification, which can reach the transmission rate of 480M/s, while the transmission rate of USB 1. 1 is only12m/s. ..
USB devices have the following advantages:
Support hot plug, easy to use.
Wide bandwidth and high speed.
More devices can be connected.
It has a simple network interconnection function.
USB interface can be connected: USB mouse, USB keyboard, external card reader, camera, digital camera, digital video camera, printer, game controller, etc.
IEEE 1394 interface
IEEE 1394 interface was originally proposed by Apple (called "Firewire" technology). At present, there are two versions, the existing IEEE 1394a and the developing IEEE 1394b, which are similar to USB interface in appearance and most functions. IEEE 1394 usually has two interfaces:
Hexagons are mostly used in Macs and desktop computers.
Quadrilateral type is mainly used for DV or notebook computers.
PS/2 interface
PS/2 interface is widely used for mouse and keyboard, among which light green interface is used for mouse and purple interface is used for keyboard. Because of the different transmission signals, the two cannot be mixed together.
audio interface
The blue interface is an audio input.
The green interface is an audio output, usually connected to speakers or headphones.
The red interface is a microphone, which is generally connected to a microphone, an earphone and a microphone.
VGA interface

Question 7: How to connect the switch cable of the computer host? The picture has the same letters as the motherboard, just sit in the right position. You can look at this, wenku.baidu/...e=view,.
Now that the motherboard has been clearly marked, just sit in the right position.
Question 8: How to plug the cable behind the desktop computer into the monitor? For the computer host, if there is only an integrated graphics card, use VGA signal line, with one end connected to the computer host integrated graphics card and the other end connected to the monitor. If you have both an integrated graphics card and a discrete graphics card, as follows:
The display signal line must be connected to the discrete graphics card. Because after the computer host is turned on, if the discrete graphics card is detected, it will automatically shield the integrated graphics card and output video signals through the discrete graphics card. If the signal line is connected to the integrated graphics card by mistake, the display will have no signal input.
