TELNET Certification
About TELNET
TELNET (short for Teletype Network) is a protocol that allows users to connect to remote computer systems and access resources on those systems. It enables users to log into a remote system and run commands as if they were sitting at the system's console. TELNET uses a client-server architecture, where a TELNET client program runs on the user's computer and connects to a TELNET server program running on the remote system.
TELNET uses a virtual terminal (VT) connection, which simulates a text-based terminal such as a VT100, to provide a command-line interface to the remote system. The VT connection is established over a TCP/IP network, and TELNET uses the standard TCP/IP port 23.
TELNET is widely used for remote administration of servers, network devices and other devices that supports TELNET protocol. It also used to test the connectivity of a host or a service to a remote host. TELNET is also used for remote login on a multi-user system, for example, Unix or Linux servers.
However, TELNET is considered to be an insecure protocol because it transmits data, including login credentials, in plaintext across the network. Therefore, it is generally recommended to use other protocols such as SSH (Secure Shell) or SFTP (Secure File Transfer Protocol) for secure remote access.

Who should take the TELNET Certification exam?
The TELNET course is recommended for network administrators, IT professionals, and individuals who are involved in managing and configuring networking devices and protocols. It is also suitable for individuals who are interested in learning about TELNET, which is a network protocol used for remote login to network devices and servers, and its use in managing and automating network tasks.
