1, broadly speaking, the data cable refers to a variety of electronic devices connected to each other, and data and information transmission of communication cables, or that the external connection between the equipment for communication channels or bridges;
2, narrowly speaking, according to the interface standard of the equipment categorized by the special data transmission line, involving the interface standard, support for the transmission function, the relevant technical requirements, etc.. For example, cell phone data cable, its interface standard has a variety of specifications, its cable includes a data cable and power cord, can be used for charging, but also with the computer equipment online;
3, in layman's terms, the commonly used data cable, are weak power class signal cable, its transmission content including digital and analog signals. Such as cats and routers in the home and other equipment connected to the use of network cables, monitors, mice, keyboards, speakers or printers and other peripherals and computers connected to the cable, as well as set-top box-related signal lines, etc.;
4, data lines are wired communication equipment connected to the essential components (equipment), the stability and reliability of its information transmission, to be preferred over the wireless communication method. The disadvantage is that the use of cable-connected devices, but also by the cable of the corresponding wiring environment, cable length and other technical requirements of the bondage, the lack of freedom of wireless communication.
