GLOSSARY 3

EIA/TIA

Electronics Industries Association/Telecommunications Industries Association. The organization that develops wiring standards for the telecommunications industry. The EIA/TIA 568 specification applies to all unshielded twisted-pair wiring schemes that work with Ethernet, Token Ring, ISDN and other networks.

EISA

Extended Industry Standard Architecture. The EISA 32-bit extended AT personal computer bus architecture is downward compatible with the 16-bit ISA architecture.

EMM386

Expanded Memory Manager. A dual-purpose memory manager that comes with MS-DOS. It provides access to the upper memory area, which enables you to free conventional memory by running device drivers in upper memory. EMM386 also uses extended memory to simulate expanded memory. Refer to Microsoft documentation for additional information.

Ethernet

A local area network standard defining a physical medium and its method of placing data, or packet signaling, on a cable. Access to the cable is based on CSMA/CD (carrier sense multiple access with collision detection).

ISA

Industry Standard Architecture. A 16-bit extension of the original IBM® PC bus architecture. The IBM Personal Computer AT® bus.

Loopback

A type of diagnostic test in which the transmitted signal is returned to the sending device after passing through all, or a portion of, a data communications link or network. A loopback test permits the comparison of a returned signal with the transmitted signal.
