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.

 

 

 

 

 

 

 

VCI

 

A Virtual Channel Identifier is a number that denotes a particular logical connection between

 

 

 

 

end stations (users or networks). See also, VPI.

WAN

 

Wide Area Networks 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 (incorrectly) 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).
