Extended data
Notebook interface
1, USB interface
USB should be a familiar interface. At present, the interface can be widely used to connect various external devices such as mouse, keyboard, printer, scanner and speaker. It should be noted that the transmission rate of the mainstream USB2.0 interface can be as high as 480Mbps, while the theoretical value of the old USB 1. 1 interface is only 12Mbps.
2.s- video output interface
S-Video looks a bit like a common mouse and keyboard interface. In fact, this interface is used to transmit the display content on the notebook to the TV. If there is a blockbuster movie in the notebook, you can share it with the whole family.
3.RJ-45 interface
RJ-45 interface is an Ethernet card interface. At present, most notebook computers have built-in Ethernet card chips on their motherboards, so an Ethernet card interface will be provided in the notes. Through this interface, users only need to insert a twisted pair that can access the Internet in broadband, and they can access the Internet in broadband.
4.RJ- 1 1 interface
RJ- 1 1 interface is a telephone line interface. Users only need to connect the telephone line to this interface of the notebook computer, and they can dial-up the Internet. Of course, only laptops with built-in modems have this interface.
5.IEEE 1394 interface
This is an interface invented by Apple. IEEE 1394 interface is mainly used to connect DV devices. Like USB interface, it supports hot plug, which is divided into two standards: IEEE 1394a and IEEE 1394b, and the transmission rate can reach 400Mbps and 800Mbps respectively. But at present, notebooks equipped with IEEE 1394b interface are rare.
6. Infrared Data Association
Infrared data association is one of the standard configurations of notebooks. Through this interface, you can easily connect with other notebook computers, PDA and mobile phones wirelessly. Its principle is the same as that of our commonly used TV remote control machine, which is characterized by strong directivity and no obstacle between two infrared ports.
