Frame Type

 

Each frame type is a separate logical network, even though they exist on one physical

 

 

 

 

network. Frame Types are 802.2, 802.3, Ethernet II (DIX) and SNAP (Sub-Network

 

 

 

 

Access Protocol).

 

 

 

 

 

 

 

FTP

 

File Transfer Protocol is an Internet file transfer service that operates on the Internet

 

 

 

 

and over TCP/IP networks. FTP is basically a client/server protocol in which a system

 

 

 

 

running the FTP server accepts commands from a system running an FTP client. The

 

 

 

 

service allows users to send commands to the server for uploading and downloading

 

 

 

 

files. FTP is popular on the Internet because it allows for speedy transfer of large files

 

 

 

 

between two systems.

 

 

 

 

 

 

 

G.SHDSL

 

A Single-pair High-speed Digital Subscriber Line is a symmetrical, bi-directional DSL

 

 

 

 

service that operates on one twisted-pair wire. The “G.” in “G.SHDSL” is defined by the

 

 

 

 

G.991.2 ITU (International Telecommunication Union) state-of-the-art industry

 

 

 

 

standard. G.SHDSL provides data rates up to 2.3 Mbits/sec. Unlike traditional HDSL

 

 

 

 

systems, which use two twisted pair, G.SHDSL reduces equipment and lease-line

 

 

 

 

costs by providing the same service using only one twisted pair. See also DSL.

 

 

 

 

 

 

 

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.

 

 

 

 

 

 

 

HDLC

 

High-level Data Link Control is a bit-oriented (the data is monitored bit by bit), link layer

 

 

 

 

protocol for the transmission of data over synchronous networks.

 

 

 

 

 

 

 

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 computer provide

 

 

 

 

several services, such as WWW and USENET.

 

 

 

 

 

 

 

HTTP

 

Hyper Text Transfer Protocol. The most common protocol used on the Internet. HTTP

 

 

 

 

is the primary protocol used for web sites and web browsers. It is also prone to certain

 

 

 

 

kinds of attacks.

 

 

 

 

 

 

 

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.

 

 

 

 

 

 

 

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.

 

 

 

 

 

 

 

Inside Wiring

 

Wiring that is done from the point of demarcation to the jack in the wall where the line

 

 

 

 

terminates.
