What are the notebook video output interfaces?
1.PC card interface
is called PCMCIA interface. It is a universal expansion port dedicated to books, and it is also called a PC card expansion slot in some articles. This expansion slot is like a PCI expansion slot for a desktop computer, and is applicable to all current storage and wireless network cards.
It is an upgraded version of PCMCIA (data exchange via PCI-Express bus). The characteristic is that the transmission bandwidth is much higher than the PC card. However, there are relatively few devices that support this bus.
3.S/PDIF interface
S/PDIF (Sony/PhilipsDigitalInterFace English abbreviation for Sony and Philips digital interface) is a digital audio output interface jointly developed by SONY and PHILIPS. Widely used in CD, sound card and household appliances. Its main function is to improve CD sound quality and give us a more pure hearing effect.
4. Network card interface (RJ-45)
At present, ordinary units or families use a local area network, which requires a laptop with a network card. For this reason, most laptops currently have an Ethernet card chip built into the motherboard, and an Ethernet card interface is provided outside the notebook. Also called RJ-45 interface. Through this type of interface, users only need to insert a twisted pair with broadband Internet access into it to achieve broadband Internet access. At present, most local area networks use twisted pair to access the Internet. Of course, if your laptop does not have an Ethernet card interface, it means that it does not have a built-in Ethernet card chip. At this time, you can buy an Ethernet card with a PC card interface on the market, and you can achieve the same function at the same time.
5. Parallel port
Parallel port is called parallel interface, or parallel port for short, that is, LPT interface, which is an extended interface using parallel communication protocol. The data transmission rate of the parallel port is 8 times faster than that of the serial port, and the data transmission rate of the standard parallel port is 1Mbps. It is generally used to connect printers and scanners. So the parallel port is also called the printing port.
6. Card reader interface
With the gradual popularization of digital products, the card reader interface is getting more and more attention, because most digital products use memory cards to store data. If users want to download the data on the memory card to a laptop, the notebook must With the same type of interface, otherwise the user must purchase an additional card reader that can read the memory card. If you have an all-in-one card reader on your notebook, it is quite convenient.
7.serial port
Stands for serial interface, abbreviated as serial port, that is, COM interface, which is an extended interface using serial communication protocol. The data transmission rate of the serial port is 115kbps ~ 230kbps, the serial port is generally used to connect the mouse and external Modem, old-fashioned camera and writing board and other devices.
8. Infrared
Because the main feature of the laptop is its strong mobility, the wireless interface has become an important part of it. Infrared interface is one of the wireless interfaces. At present, general notebook computers are equipped with infrared interface. Through the infrared interface of the notebook, users can achieve wireless connection with electronic devices (such as desktop computers, mobile phones, handheld computers, etc.) that also have infrared interfaces, thereby completing the data transmission process of the two. During transmission, there must be no obstruction between the two infrared interfaces.
Because the cost of the built-in infrared chip is not very high, and its safety is good, the technology is mature, and the penetration rate is high, so most portable electronic devices (such as mobile phones, handheld computers, etc.) are equipped with infrared interfaces at the same time. Laptop users can easily connect wirelessly with these devices.
9. Bluetooth interface
This interface was initiated and promoted by Ericsson. Bluetooth technology is more advanced than infrared technology. Compared with infrared technology, it is faster and has wider signal coverage. The most important thing is that it does not have a strong directivity like infrared technology. Just put it in the range that Bluetooth can cover, no longer need to aim like infrared.
