Telnet :: essays research papers

TelnetPURPOSE OF THIS REPORT     Before gophers, hypertext, and sophisticated web browsers, telnet wasthe primary marrow by which computer users connected their machines with othercomputers around the world. Telnet is a plain ASCII end point emulationprotocol that is still used to access a mutation of information sources, mostnotably libraries and local BBSs. This report will trace the history and usageof this still popular and widely used protocol and pardon where and how itstill manages to fit in today.HISTORY AND FUTURE OF TELNET     "Telnet" is the accepted name of the Internet protocol and the commandname on UNIX systems for a type of terminal figure emulation program which allows usersto log into remote computer networks, whether the network being targeted forlogin is physically in the next room or halfway around the globe. A commonprogram feature is the ability to emulate several diverse types of terminals--ANSI, TTY, vt52 , and more. In the early days of networking just about ten to fifteenyears ago, the " lucre" more or less consisted of telnet, FTP (file transferprotocol), crude email programs, and news reading. Telnet made library catalogs,online services, bulletin boards, databases and other network services usableto casual computer users, although not with the friendly graphic user interfacesone sees today.     Each of the early net income functions could be invoked from the UNIXprompt, however, each of them used a assorted client program with its ownunique problems. Internet software has since greatly matured, with modern webbrowsers (i.e. Netscape and Internet Explorer) easily handling the WWW protocol(http) on with the protocols for FTP, gopher, news, and email. Only thetelnet protocol to this day requires the use of an external program.     Due to problems with printing and saving and the primitive look andfeel of telnet connections, a mov ement is underway to metamorphose informationresources from telnet- kindly sites to full fledged web sites. However, itis estimated that it will still take several years before quality web interfacesexist for all of the resources like a shot currently uncommitted only via telnet.Therefore, k straightwaying the underlying command structure of terminal emulationprograms like telnet is likely to remain necessary for the networkingprofessional for rough time to come.ADVANTAGES AND DISADVANTAGES OF TELNET     The chief advantage to the telnet protocol today lies in the fact thatmany services and most library catalogs on the Internet remain convenient todayonly via the telnet connection. Since telnet is a terminal application, manysee it as a mere holdover from the days of mainframe computers and minicomputers.With the recent interest in $500 Internet terminals may foretell a resurgenceTelnet essays research papers TelnetPURPOSE OF THIS REPORT   &nb sp Before gophers, hypertext, and sophisticated web browsers, telnet wasthe primary performer by which computer users connected their machines with othercomputers around the world.
