90 nanometer is the buzzword of choice (2000-2004) for an advanced semiconductor manufacturing process that combines higher-performance, lower-power transistors, strained silicon, high-speed copper interconnects and low-k dielectric material. Some of the new technologies in 90 nm are strained silicon which causes one type of transistor to switch faster, low-power transistors which are only 50 nm in size, and seven layers of copper interconnects which provide a cost-effective improvement in logic density. The low-k insulator between each of the copper interconnect layers reduces wire to wire capacitance.
Short for authentication, authorization and accounting, a system in IP-based networking to control what computer resources users have access to and to keep track of the activity of users over a network. Authentication is the process of identifying an individual, usually based on a username and password. Authentication is based on the idea that each […]
Short for Advanced Audio Coding, one of the audio compression formats defined by the MPEG-2 standard. AAC is sometimes referred to as MPEG-2 NBC (not backwards compatible) because it is not compatible with the MPEG-1 coding scheme. AAC boasts higher quality audio reproduction than MP3 and requires 30% less data to do so.
Short for Advanced Authoring Format, a multimedia file format introduced by Microsoft in 1998. The goal of AAF is to provide a common file format that multimedia authoring applications can use so that it’s possible to develop a multimedia presentation in one application and then edit it in a second application. This will allow designers […]
Short for AppleTalk Address Resolution Protocol, a protocol for mapping a device’s physical hardware address to a temporary Appletalk network-assigned address in Macintosh computer LANs. When a protocol stack sends a data packet, the protocol address specifies the destination. The data link layer relies on AARP to translate the protocol address into the hardware address […]
Short for Apple Attachment Unit Interface, A 14-position, 0.050-inch-spaced ribbon contact connector. Except for the pins that supply power, each AAUI signal has the same description, function, and electrical requirements as the AUI (Attachment Unit Interface) signal. The AAUI is the Apple standard used to connect Ethernet transceivers in early Power Macintosh and Quadra computers.
