Explanation
USB (Universal Serial Bus) is by far the most common interface for external optical drives including CD-ROM drives. USB is universally supported across virtually all computers and operating systems, is easy to connect (plug-and-play), can provide bus power eliminating the need for a separate power adapter, and is available at low cost. FireWire (IEEE 1394) and eSATA are less common and not available on all systems. Ethernet is a network interface and is not used to connect local peripheral devices such as optical drives.
