I would like to share with you what interfaces there are in the notebook computer. I believe most people don't know much about it, so share this article for your reference. I hope you will learn a lot after reading this article. Let's learn about it together.

1.USB interface

The full name of USB is that Universal Serial Bus,USB supports hot plug and plug and play, so USB interface has become the most important interface mode. USB interface can be used to connect up to 127kinds of peripherals, such as mouse, modulation

2.DVI interface

Digital Visual Interface DVI is an interface standard introduced by DDWG (Digital Display Working Group), a digital display working group composed of Silicon Image, Intel, Compaq, IBM, HP, NEC, Fujitsu and other companies in 1999. The advantages of the interface are fast transmission speed and clear picture. DVI transmits digital signals, and digital image information is directly transmitted to the display device without any conversion, thus reducing the conversion process and greatly saving time, so it is faster, effectively eliminates the phenomenon of shadow, and uses DVI for data transmission, the signal is not attenuated.

3.HDMI interface

HDMI, the English full name is High Definition Multimedia Interface, and the Chinese name is the abbreviation of high-definition multimedia interface. HDMI can transmit uncompressed HD video and multi-channel audio data with high quality and the highest data transmission speed is 5Gbps. At the same time, there is no need to carry out digital / analog or analog / digital conversion before signal transmission, which can ensure the highest quality of audio-visual signal transmission.

4. Power interface

The power interfaces of different notebooks are different, not only in terms of voltage, but also sometimes in shape. For example, some brands will design the power interface as a polygon rather than a circle, so as to avoid all kinds of situations caused by the possible rotation of the connector, and some notebook power interfaces are magnetic, when someone accidentally stumbles over a cable from the side, the power cord will fall off automatically, so as to avoid falling to the ground together with the notebook.

5. Card reader interface

After you can insert the card reader into the slot of the notebook reader port and install the required drivers, the notebook will treat the memory card in the card reader as a removable memory, so that the memory card can be read and written through the card reader.

6. Headphone port and microphone port

"all notebooks will provide two small round holes at the front of the fuselage or on the left and right sides. They are the headphone port and the microphone connector. They look exactly the same. The only way to distinguish them is to look at the logo next to the interface. And keep in mind that some books will be distinguished by color.

7. Burglar lock hole

In the protection of the whole machine, now the most commonly used are some anti-theft locks. Now most notebooks are equipped with anti-theft lock slots, you can buy a steel wire anti-theft lock to lock, that is, one end is inserted into the lock slot, and the other end is wound on an object that is difficult to move, so that the most basic anti-theft requirements can be achieved. Some of these anti-theft locks can only be opened with a key, while others have to enter a password to take it off. These anti-theft locks can be seen in general notebook stores. For the sake of the safety of notebooks, merchants usually use anti-theft locks when they are displayed, and ordinary home users or office users will also lock their notebooks when they go out.

8. Optical drive carrier (hard drive carrier) port

As the name implies, the optical drive carrier port is used for the optical drive. In addition to different types of optical drives, generally replaceable components also support a second battery and hard disk, media that can connect the machine to the hard disk and exchange data, and some products also support small numeric keypads.

9. Bluetooth interface

A pretty popular wireless interface. Compared with the infrared interface, it has the characteristics of faster speed and wider signal coverage, and the most important thing is that it will not have a strong direction. As long as the connecting device is within the coverage of Bluetooth, you don't have to aim like an infrared interface.
