EDO RAM (Extended Data Out Random Access Memory)
A newer, faster kind of DRAM, which holds the most recently requested data in a cache after it’s released. EDO
RAM can increase performance by up to 20%. Generally used with Intel's Triton chipset and Pentium processors, EDO
RAM was introduced in 1995. EDO RAM bus speeds range up to 33MHz.

Email (Electronic Mail)
E-mail is an electronic mail message sent from a host computer to a remote computer, so it provides a method by
which computer users can exchange messages with each other over a network. Email is probably the most widely-used
communications tool on the Internet. There are many quirky conventions to Email, but most entail a "To:",
"From:", and "Subject:" line. One of Email's advantages is its ability to be forwarded and
replied to easily. If an email is badly received by a group or user, the sender is likely to get "flamed".

Ethernet
Ethernet is a network protocol invented by Xerox Corporation and developed jointly by Xerox, Intel and Digital
Equipment Corporation (DIX). Ethernet networks use CSMA/CD and run over a variety of cable types at 10 Mbps (megabits
per second). So, Ethernet is a commonly used type of local area network (LAN). Ethernet is a standard and probably
the most popular connection type for LANs (Local Area Networks). In an Ethernet configuration, computers are connected
by coaxial or twisted-pair cable where they contend for network access using a Carrier Sense Multiple Access with
Collision Detection (CSMA/CD) paradigm. Ethernet can transfer information at up to 10 Megabit-per-second (Mb/s).
