Terminal

 

A device that allows you to send commands to a computer somewhere else. At a minimum, this

 

 

usually means a keyboard and a display screen and some simple circuitry.

 

 

 

Terminal Software

 

Software that pretends to be (emulates) a physical terminal and allows you to type commands to

 

 

a computer somewhere else.

 

 

 

TFTP

 

Trivial File Transfer Protocol is an Internet file transfer protocol similar to FTP (File Transfer

 

 

Protocol), but it is scaled back in functionality so that it requires fewer resources to run. TFTP

 

 

uses the UDP (User Datagram Protocol) rather than TCP (Transmission Control Protocol).

 

 

 

UDP

 

UDP is a connectionless transport service that dispenses with the reliability services provided by

 

 

TCP. UDP gives applications a direct interface with IP and the ability to address a particular

 

 

application process running on a host via a port number without setting up a connection session.

 

 

 

URL

 

(Uniform Resource Locator) URL is an object on the Internet or an intranet that resides on a

 

 

host system. Objects include directories and an assortment of file types, including text files,

 

 

graphics, video and audio. A URL is the address of an object that is normally typed in the

 

 

Address field of a Web browser. The URL is basically a pointer to the location of an object.

 

 

 

Virtual Connection

 

A link that seems and behaves like a dedicated point-to-point line or a system that delivers

(VC)

 

packets in sequence, as happens on an actual point-to-point network. In reality, the data is

 

 

delivered across a network via the most appropriate route. The sending and receiving devices

 

 

do not have to be aware of the options and the route is chosen only when a message is sent.

 

 

There is no pre-arrangement, so each virtual connection exists only for the duration of that one

 

 

transmission.

 

 

 

WAN

 

Wide Area Network s link geographically dispersed offices in other cities or around the globe.

 

 

Just about any long-distance communication medium can serve as a WAN link, including

 

 

switched and permanent telephone circuits, terrestrial radio systems and satellite systems.

WWW

 

(World Wide Web) - Frequently used when referring to "The Internet", WWW has two major

 

 

meanings - First, loosely used: the whole constellation of resources that can be accessed using

Gopher, FTP, HTTP, telnet, USENET, WAIS and some other tools. Second, the universe of hypertext servers (HTTP servers).
