Introduction to TELNET
Pre-Requisite: Types of Network Protocol
TELNET stands for Teletype Network. It is a type of protocol that enables one computer to connect to the local computer. It is used as a standard TCP/IP protocol for virtual terminal service which is provided by ISO. The computer which starts the connection is known as the local computer.
The computer which is being connected to i.e. which accepts the connection known as the remote computer.
