AGTL Signaling: (Assisted Gunning Transistor Logic) AGTL and AGTL+ use the same signaling protocol only at different voltage levels. AGTL+ operates at 1.5V signaling levels, while AGTL operates at 1.25V.

Algorithm: A formal set of instructions that can be followed to perform a specific task, such as a mathematical formula or a set of instructions in a computer program.

Alias: A shortcut or 'friendly name' that points to a file folder or application. As an example, when you enter in a user name for an application, this user name would be an 'alias'.

Aliasing: This refers to the distortion in a sound or image generation. A sound distortion occurs when digitally recording high frequencies with a low sample rate. An image distortion occurs when a pr . . . View Full Definition
