SCSI cables are viewed as the opposite of USB cables. SCSI stands for Small Computer System Interface. SCSI cables have been in use for quite a number of years, come in all shapes and sizes. USB cables are new, easy to use and relatively simple.

SCSI cables, referred to by computer geeks as "scuzzy" cables, connect computers to various storage devices, mostly hard drives of one type or another. The vast number and variety available requires some fundamental information and knowledge about SCSI cables before buying.

There are three main kinds you are most likely to encounter:

1. An external SCSI cable is used to connect a computer to an external hard drive of some kind; it tends to look very similar to a printer cable.

2. An internal SCSI cable is seen when you open the computer case, because it's used to connect to the computer's internal drive.

3. A SCSI adapter is typically a small device to adapt 2 different types of SCSI connectors.
