Analysis of the functions of common laptop interfaces

If you only use your laptop as a tool for document processing and downloading things from the Internet, then you're really not making full use of it. In fact, through various interfaces on the side of the machine, it can do a lot more. For example, you can use the video interface to output great movies/TV series to a large LCD screen or liquid crystal TV for viewing. If you pair it with a wireless keyboard/mouse or wireless controller, playing games in the living room while lying on the couch becomes effortless. Through the IEEE1394 interface, we can quickly import video recordings from a DV into the hard drive; and card readers provide convenience for data exchange between phones/DCs and laptops, etc. Below, we will introduce the functions and main purposes of these interfaces one by one.
