When it comes to attaching storage to computers, ATA (AT attachment) is the most prevalent method. The characters AT, which stand for “advanced technology,” come from the name of the first 80286-based IBM PC. ATA drives are found mostly on desktop systems and laptops. Higher-end systems, often called “servers,” utilize a connection technique called SCSI (Small Computer System Interface) parallel bus architecture. These systems may have several such SCSI buses attached to them. The more SCSI buses that can be effectively connected to a system, the higher the data input/output (I/O) capabilities of that system.
