What Does Telnet (TN) Mean?

Techopedia Explains Telnet (TN)
Designed for remote server access, management and client/server architectures, Telnet works through a purpose-built program that provides connectivity between a remote computer/server and host computer. Upon providing correct login and sign-in credentials, a user may access a remote system’s privileged functionality. Additionally, Telnet’s commands may be executed on a supported client or server device.
Telnet sends all messages in clear text and has no specific security mechanisms. Thus, in many applications and services, Telnet has been replaced by Secure Shell (SSH).
✳️ The main task of the internet is to provide services to users. For example, users want to run different application programs at the remote site and transfers a result to the local site. This requires a client-server program such as FTP, SMTP. But this would not allow us to create a specific program for each demand.
✳️ The better solution is to provide a general client-server program that lets the user access any application program on a remote computer. Therefore, a program that allows a user to log on to a remote computer. A popular client-server program Telnet is used to meet such demands. Telnet is an abbreviation for Terminal Network.
✳️ Telnet provides a connection to the remote computer in such a way that a local terminal appears to be at the remote side.
