EISA
Extended Industry Standard Architecture. The EISA 32-bit
extended AT personal computer bus architecture is
backward-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.
NDIS
Network Driver Interface Specification. Defines the LAN
Manager network driver architecture and interfaces that let a
DOS or OS/2 system support network adapters. This
architecture provides a standardized way to write drivers for
network adapters.
