Alternatively referred to as a cord, connector or plug, a cable is one or more wires covered in plastic that transmit power or data between devices or locations. The picture is an example of what the power cord may look like for your computer or monitor. The power cord is one example of thousands of other cables found in and around computers.
There are two main types of computer cables, a data 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 both good examples of power cables.
