DTE

 

Originally, the DTE (data terminal equipment) was a dumb terminal or printer, but today it

 

 

 

 

is a computer, or a bridge or router that interconnects local area networks.

 

 

 

 

 

 

 

EMI

 

ElectroMagnetic Interference. The interference by electromagnetic signals that can cause

 

 

 

 

reduced data integrity and increased error rates on transmission channels.

 

 

 

 

 

 

 

Encapsula-

 

A process of putting information into packets. One layer encloses or encapsulates other

 

 

tion

 

layers of the packet; for example, TCP/IP uses encapsulation. A whole separate packet can

 

 

 

 

even be encapsulated into another with a technique called IP tunneling.

 

 

 

 

 

 

 

Ethernet

 

A very common method of networking computers in a LAN. There are a number of

 

 

 

 

adaptations to the IEEE 802.3 Ethernet standard, including adaptations with data rates of 10

 

 

 

 

Mbits/sec and 100 Mbits/sec over coaxial cable, twisted-pair cable, and fiber-optic cable.

 

 

 

 

The latest version of Ethernet, Gigabit Ethernet, has a data rate of 1 Gbit/sec.

 

 

 

 

 

 

 

FAQ

 

(Frequently Asked Questions) -- FAQs are documents that list and answer the most common

 

 

 

 

questions on a particular subject.

 

 

 

 

 

 

 

FCC

 

The FCC (Federal Communications Commission) is in charge of allocating the

 

 

 

 

electromagnetic spectrum and thus the bandwidth of various communication systems.

 

 

 

 

 

 

 

Flash

 

The nonvolatile storage that can be electrically erased and reprogrammed so that data can be

 

 

memory

 

stored, booted, and rewritten as necessary.

 

 

 

 

 

 

 

Gateway

 

A gateway is a computer system or other device that acts as a translator between two systems

 

 

 

 

that do not use the same communication protocols, data formatting structures, languages,

 

 

 

 

and/or architecture.

 

 

 

 

 

 

 

Host

 

Any computer on a network that is a repository for services available to other computers on

 

 

 

 

the network. It is quite common to have one host machine provide several services, such as

 

 

 

 

WWW and USENET.

 

 

 

 

 

 

 

IANA

 

Internet Assigned Number Authority acts as the clearinghouse to assign and coordinate the

 

 

 

 

use of numerous Internet protocol parameters such as Internet addresses, domain names,

 

 

 

 

protocol numbers, and more. The IANA Web site is at http://www.isi.edu/iana.

 

 

 

 

 

 

 

ICMP

 

Internet Control Message Protocol is a message control and error-reporting protocol between

 

 

 

 

a host server and a gateway to the Internet. ICMP uses Internet Protocol (IP) datagrams, but

 

 

 

 

the messages are processed by the TCP/IP software and are not directly apparent to the

 

 

 

 

application user.

 

 

 

 

 

 

 

internet

 

(Lower case i) Any time you connect 2 or more networks together, you have an internet.
