EDI (Electronic Data Interchange) - EDI is the computer-to-computer exchange of business information using a public standard. EDI is a central part of e-commerce, because it enables companies to exchange business information electronically much faster, cheaper and more accurately than is possible using paper-based systems. The parties who exchange EDI transmissions are referred to as trading partners.
EIGRP (Enhanced Interior Gateway Routing Protocol) - EIGRP is a Cisco proprietary distance vector routing protocol, with optimizations to minimize both the routing instability incurred after topology changes, as well as the use of bandwidth and processing power in the router. For EIGRP, separate routing tables are maintained for IP, IPX and AppleTalk protocols. However, routing update information is still forwarded with a single protocol.

 EISA (Extended Industry Standard Architecture) - EISA is a bus standard for IBM compatible computers. It was announced in late 1988 by PC clone vendors as a counter to IBM's use of its proprietary MicroChannel Architecture (MCA) in its PS/2 series. EISA extends the ISA bus architecture to 32 bits and allows more than one CPU to share the bus. The bus mastering support is also enhanced to provide access to 4 GB of memory. Unlike MCA, EISA can accept older XT and ISA boards — the lines and slots for EISA are a superset of ISA. Although somewhat inferior to MCA, EISA was much favoured by manufacturers due to the proprietary nature of MCA, and even IBM produced some machines supporting it. It was somewhat expensive to implement (though not as much as MCA), so it never became particularly popular in desktop PCs. However, it was reasonably successful in the server market, as it was better suited to bandwidth-intensive tasks (such as disk access and networking). Most EISA cards produced were either SCSI or network cards. EISA is not commonly seen anymore.
Ethernet - Created by Xerox, Intel, and DEC in 1976, Ethernet has been standardized as IEEE 802.3. Ethernet is a large and diverse family of frame-based computer networking technologies for local area networks (LANs). It defines a number of wiring and signaling standards for the physical layer, two means of network access at the Media Access Control (MAC)/Data Link Layer, and a common addressing format. The original implementations of Ethernet used coaxial cable in a bus topology. The current star-topology, twisted pair or fiber optic wiring form has become the most common LAN technology in use, largely replacing competing LAN standards such as token ring, FDDI, and ARCNET. There are many different forms of Ethernet currently in use varying from 10Base-T which utilizes twisted pair wiring at speeds of 10mbps, to 1000Base-LX which operates at speeds up to 1gbps over fiber optic cabling.
