Telnet is an application designed for reliable communication via a virtual terminal. Telnet was one of the first protocols developed for use over TCP/IP.
Telnet is carried inside the payload of TCP (encapsulated in TCP). Information is communicated as ASCII Text. Telnet utilizes TCP/IP to support communication. Telnet provides access to the command prompt remotely. Telnet is an Application (operates at the OSI Model's Application Layer). Telnet provides reliable communication via TCP.
Telnet is one of the earliest protocols developed.
Telnet is an Application layer protocol providing reliable unencrypted communication allowing users to access the command line of a computer from a remote location and provides very little security.
