A through G
AP (networking, wireless) = Access Point - A connection point where wireless clients clients attach to a wired network, can be configured to extend wireless coverage in repeater mode.
ATA: Analog Telephone Adapter - An ATA is a device which provides an interface between a traditional "Plain Old Telephone Service" (POTS) telephone line and a computer system, potentially including Voice Over Internet Protocol (VOIP) bridging capabilities. Commonly found on ATAs are at least one standard telephone jack and one Ethernet jack. Examples of ATAs include the Linksys/Sipura SPA-3102 and the Obi110, among others.
ATSC: Advanced Television Systems Committee - ATSC is used to denote the North American digital television broadcast standards. ATSC standards replace the older, analog NTSC standards used before US Federal mandate required all broadcasters to switch to digital broadcast for Over The Air (OTA) television transmissions. The European equivalent is called DVB. Supported resolutions include 480i, 480p, 720i, 720p, 1080i and 1080p, among others.
BIOS: Basic Input Output System - A set of commands that a computer uses to understand itself and its internal components, used to initialize a computer prior to loading a full Operating System (OS).
