With the advent of various external digital devices, small interface choices have become important. When choosing a laptop, you should not only pay attention to its configuration, brand, appearance, but also the richness of the interface is also an important reference point. Analyze the commonly used interfaces today. This is very familiar to everyone, USB is the most frequently used interface for notebook computers. USB is the abbreviation of English Universal Serial Bus, meaning "Universal Serial Bus" in Chinese. After years of development, USB has now evolved to version 3.1. Most of the USB models currently sold are 2.0 standards, and USB 1.1 products have been eliminated. The theoretical transfer rate of USB2.0 is 480Mbps, which is about 60MB/sec, but the transmission speed in actual use is lower than this theoretical value. At present, the new USB 3.1 has the characteristics of fast transmission rate, theoretically can reach 10Gbps, twice as fast as the previous generation, and can be backward compatible with USB2.0 devices. Easy to distinguish, generally 3.0 and above interfaces are blue. High-definition multimedia interface (English: High DefiniTIon MulTImedia Interface, HDMI) is a digital video/audio interface technology. It is a dedicated digital interface for image transmission. It can transmit audio and video signals at the same time without counting before signal transmission. / mode or analog / digital conversion. Only one HDMI cable is needed to connect the computer to the TV or the big screen, and enjoy high-definition video and audio entertainment, and the current LCD TVs are equipped with an HDMI interface as standard. LAN is the network cable interface we often talk about, through which it realizes wired connection to the Internet. Most of the current notebooks are equipped with a network cable interface, and some ultra-polar products are limited by the design consideration of the thickness of the body, and will be switched by the network cable interface. To achieve. The VGA interface is a computer display standard that IBM introduced in 1987 using analog signals. The VGA interface is a dedicated interface for the computer to use VGA standard output data. The general VGA interface has a total of 15 pins, divided into 3 rows, 5 holes per row. In addition, there are power interfaces, audio interfaces, etc. For different brands and different models of computers, the types and number of interfaces will be different. It is also important for the computer to protect the interface. Daily maintenance should be "waterproof, dustproof, anti-static; light plug, light pull, and more cover", which will help extend the life of the notebook.
