Question: What is TELNET?
Answer:
TELNET is a network protocol that provides a way to establish a remote terminal session between a client and a server over a computer network. It allows a user to log in to a remote computer or server and interact with it as if they were physically present at that machine.
The TELNET protocol enables the transmission of text-based commands and responses between the client and server. It operates on the application layer of the TCP/IP protocol suite and uses TCP (Transmission Control Protocol) as its transport protocol.
By establishing a TELNET session, a user can access a remote system's command-line interface and execute commands, run applications, retrieve information, and perform various operations on the remote machine.
TELNET was one of the early protocols used for remote login and command-line access on the internet. However, due to security vulnerabilities associated with transmitting data in plain text, TELNET has been largely replaced by more secure protocols such as SSH (Secure Shell).
In summary, TELNET is a network protocol that enables remote terminal access and allows users to connect to and interact with remote computers or servers over a network.
MCQ : The general client-server program in the Internet is _________
- FTP
- TFTP
- TELNET
- none of the above
TELNET is a network protocol that provides a client-server architecture for remote terminal access and communication. It allows a user on one computer (the TELNET client) to connect to and access a remote computer or server (the TELNET server) over a network.
The TELNET client program establishes a connection with the TELNET server using the TELNET protocol. Once the connection is established, the client can send commands and input to the server, and the server responds by sending output and data back to the client.
TELNET was widely used in the early days of the internet to enable remote login and command-line access to remote systems. It provides a text-based interface that allows users to interact with the remote server as if they were directly connected to it through a terminal.
It is worth noting that TELNET operates at the application layer of the TCP/IP protocol suite and has been largely replaced by more secure protocols such as SSH (Secure Shell) for remote access due to security concerns.
To summarize, TELNET is a client-server protocol used for remote terminal access and communication, allowing a user to connect to a remote server and interact with it through a text-based interface.
