1. DPMI - Created for Windows version 3.0, DPMI is an industry standard for an interface that allows DOS applications to access extended memory of the 80286-, 80386-, and 80486-based PC architecture while maintaining system protection.
2. VRRP - Short for Virtual Router Redundancy Protocol. An election protocol that dynamically assigns responsibility for one or more virtual router(s) to the VRRP router(s) on a LAN, allowing several routers on a multiaccess link to utilize the same virtual IP address. A VRRP router is configured to run the VRRP protocol in conjunction with one or more other routers attached to a LAN. In a VRRP setup, one router is elected as the master router with the other routers acting as backups in case of the failure of the master router.
3. UDDI - Short for Universal Description, Discovery and Integration. A Web-based distributed directory that enables business to list themselves on the Internet and discover each other, similar to a traditional phone book's yellow and white pages.
4. DMZ - A Demilitarized Zone is used by a company that wants to host its own Internet services without sacrificing unauthorized access to its private network. The DMZ sits between the Internet and an internal network's line of defense, usually some combination of firewalls and bastion hosts. Typically, the DMZ contains devices accessible to Internet traffic, such as Web (HTTP ) servers, FTP servers, SMTP (e-mail) servers and DNS servers.
5. DACS - A digital switching device in telecommunications for routing T1 lines. The DACS can cross-connect any T1 line in the system with any other T1 line also in the system. DACS can also connect any DS-0 channel or group of channels on a T1 line to any DS-0 time slots of any other line.
