Uses of peripheral connecting wires

The popularity of computers and the rapid development of technology have eliminated many computer peripherals; the connection methods of computer peripherals are also diverse, from the early PS2 interface that supports the keyboard and mouse and the 25-pin large parallel port transmission line of the old printer to the present HDMI video cable, with the update of the equipment, there will be more peripheral cables with different interfaces in the future; today I will lead you to review the standard cables of computer peripheral peripherals.

AV video cable; In the DVD era, this is a new generation of transmission cable upgraded from RF cable, which separates the transmission of sound and image for the first time; AV cables are still widely used by everyone. AV audio cable; mainly used to connect the computer to the power amplifier equipment, and input audio from the computer to the audio equipment.
