mutex
(1) Short for mutual exclusion object. In computer programming, a mutex is a program object that allows multiple program threads to share the same resource, such as file access, but not simultaneously. When a program is started, a mutex is created with a unique name. After this stage, any thread that needs the resource must lock the mutex from other threads while it is using the resource. The mutex is set to unlock when the data is no longer needed or the routine is finished.
(2) When spelled MuTeX, a package of macros for the TeX typesetting system that supports musical notation. MuTeX was written by Andrea Steinbach and Angelika Schofer, as a master’s thesis at Rheinische Friedrich-Wilhelms University.

- NAND
NAND Flash architecture is one of two flash technologies (the other being NOR) used in memory cards such as the CompactFlash cards. It is also used in USB Flash drives, MP3 players, and provides the image storage for digital cameras. NAND is best suited to flash devices requiring high capacity data storage. NAND flash devices […]
- NAPT
NAPT, or Network Address Port Translation, is a method by which many network addresses and their TCP/UDP (Transmission Control Protocol/User Datagram Protocol) ports are translated into a single network address and its TCP/UDP ports. NAPT allows mapping of tuples of the type (local IP addresses, local TU port number) to tuples of the type (registered […]
- NAS
(1) Short for network-attached storage. (2) Short for network access server.
- Network Address Translation NAT
Short for Network Address Translation, an Internet standard that enables a local-area network (LAN) to use one set of IP addresses for internal traffic and a second set of addresses for external traffic. A NAT boxlocated where the LAN meets the Internet makes all necessary IP address translations. NAT serves three main purposes: Provides a […]
