| AC'97 |
| The Audio Codec '97 (AC'97) specification defines how an audio codec (AC), a modem codec (MC), an audio/modem codec (AMC) or both an AC and an MC be attached system logic (ie. the chipset of motherboard), and intends to replace the ISA interface.
With AC'97 there's need for only a modem riser (MR) card or an audio/modem riser (AMR) card with corresponding codec on it to perform modem and/or audio function, which is more cost-effective. |

| AGP |
| AGP (Accelerated Graphics Port) is an interface developed by Intel Corporation. It is based on PCI, but is designed especially for the throughput demands of 3-D graphics.The AGP channel is 32 bits wide and runs at 66 MHz. This translates into a total bandwidth of 266 MBps (AGP 1X), as opposed to the PCI bandwidth of 133 MBps. AGP also supports two optional faster modes, with throughputs of 533 MBps (AGP 2X) and 1.07 GBps (AGP 3X). |

| AMR |
| AMR (Audio Modem Riser) is Intel's specification on motherboard design. Motherboard with this type of architecture allows for designs without analog I/O functions. However, these functions can be added by the codec chip on a riser card, which plugs into the motherboard perpendicularly, resulting in better audio quality and modem solutions. |

| AT |
| Advanced Technology (AT) was the original form factor of IBM's PC. The older style motherboard that uses a 5-pin (large) socket for the AT-style keyboard. |

|
| ATA |
| ATA (Advanced Technology Attachment) also known as IDE (Integrated Drive Electronics), it is a disk drive implementation that integrates the controller on the disk drive itself. e.g. ATA100 enables the ATA throughput to reach 100MB per second. |

|
| ATX |
| The newer style motherboard that uses the smaller PS/2 style keyboard and which also has the PS/2 mouse socket, parallel port socket and serial port sockets soldered to the motherboard. |
