There are two main types of computer cables, a data cable (interface cable) and a power cable. A data cable is a cable that provides communication between devices. For example, the data cable (i.e., DVI, HDMI, or VGA) that connects your monitor to your computer allow it to display a picture on the monitor. Other popular examples of data cables include the CAT5, IDE/EIDE, SATA, and USB cables. A power cable is any cable that powers the device. For example, the power cord that connects to your computer and a Molex style cable inside the computer are examples of power cables.


USB cables can act as a power and an interface cable. For example, plugging your smartphone into your computer lets you transfer information to and from the phone and also charges it at the same time.
