Hi
What is Telnet? Hi

Telnet is a contraction of the two words Telecommunications Network, and is one of the major

network protocols used on the Internet. It is one of the earliest network protocols, and one of

the only original protocols still in common use on the internet. It was developed in 1969, with

the RFC 15, and has evolved over the years to be a robust protocol, although with mounting

security concerns it is often foregone in place of the secure SSH protocol.

Unlike the graphical interfaces of the HTTP protocol, which have given us the World Wide Web,

telnet is a text-based protocol. The original purpose of telnet was to have an easy interface

for terminals to interact with one another, using relatively simple command structures and

accessible interfaces. Although still in use, telnet is rarely used by the majority of the

internet-browsing public, who instead use HTTP browsers and email clients for the majority of

their connections.

Thanks

Hi
Telnet is a protocol that allows you to connect to remote computers (called hosts) over a TCP/IP network (such as the Internet). You use software called a telnet client on your computer to make a connection to a telnet server (i.e., the remote host). Once your telnet client establishes a connection to the remote host, your client becomes a virtual terminal, allowing you to communicate with the remote host from your computer. In most cases, you'll need to log into the remote host, which requires that you have an account on that system. Occasionally, you can log in as guest or public without having an account.

Telnet clients are available for all major operating systems.

Command-line telnet clients are built into most versions of Mac OS X, Windows (95 and later), Unix, and Linux. To use them, go to their respective command lines (i.e., the Terminal application in Mac OS X, the shell in Unix or Linux, or the DOS prompt in Windows), and then enter:

Hi

The telnet protocol helped overcome this difficulty. By using a simple suite of commands, users could log in to a distant terminal and ask the mainframe there to undertake whatever processes they needed accomplished. The results would come back to them through telnet, and it was as though they were sitting in front of the terminal itself. In many ways, telnet helped revolutionize the way research was done, and helped build what would eventually become the internet we know today.

Hi

Telnet is an old computer protocol (set of programmatic rules). Telnet is famous for being the original Internet when the Net first launched in 1969. Telnet stands for 'telecommunications network', and was built to be form of remote control to manage mainframe computers from distant terminals. In those original days of large mainframe computers, telnet enabled research students and professors to 'log in' to the university mainframe from any terminal in the building. This remote login saved researchers hours of walking each semester. While telnet pales in comparison to modern networking
