Advanced Technology Attachment (ATA), also known as AT attachment or AT attachment Packet Interface (ATAPI), is a standard interface for connecting storage devices such as hard disks and CD-ROM drives inside personal computers. Many terms and synonyms for ATA exist, including abbreviations such as IDE, ATAPI, and UDMA. ATA standards only allow cable lengths up to 18 inches (up to 450 mm) although cables up to 36 inches (900 mm) can be readily purchased, so the technology normally appears as an internal computer storage interface. It provides the most common and the least expensive interface for this application.

Athlon is the brand name applied to a series of different x86 processors designed and manufactured by AMD. The original Athlon, or Athlon Classic, was the first seventh-generation x86 processor and, in a first, retained the initial performance lead it had over Intel's competing processors for a significant period of time. AMD has continued the Athlon name with the Athlon 64, an eighth-generation processor featuring AMD64 technology.

An Attachment Unit Interface (AUI) is a 15 pin connection that provides a path between a node's Ethernet interface and the Medium Attachment Unit, sometimes known as a transceiver. It is the part of the IEEE Ethernet standard located between the MAC and the MAU. An AUI cable may be up to 50 metres long, although frequently the cable is omitted altogether and the MAU and MAC are directly attached to one another.

Auxiliary devices (AUX) are peripheral devices to support computers to do its job such as printers, scanners, and modems.

Audio Video Interleave (AVI) is the file format for Microsoft's Video for Windows standard.

Backbone is the main network that connects nodes. The term is often refered as the main network connections composing the Internet.

Backlighting is a technique used to make flat-panel displays easier to read. The back layer of the display is illuminated so that the foreground appears sharper in contrast with the background.

Backplane is the physical interface module in many network devices such as a route or a switch that connects between an interface processor or card and the data buses and the power distribution buses inside a chassis.

Backside bus connects the CPU to a Level 2 cache while the frontside bus connects the CPU to the main memory.
