Telnet
Telnet stands for Teletype Network. Through local area networks or the Internet, remote systems' virtual terminals can be accessed via the client/server application protocol known as Telnet. It is an 8-bit bidirectional communication protocol. Connecting terminal devices and terminal-oriented operations was its primary objective.
The Telnet protocol was developed to enable remote terminal access and control over minicomputers and mainframes in the late 1960s. It was first intended to be an easy and safe way to establish a connection with a remote system. With the use of a terminal or command-line interface, users may connect to remote machines thanks to this protocol.
Using the Telnet protocol, the user establishes a connection to the server by typing telnet hostname port into a command line. Next, by entering particular Telnet commands into the Telnet prompt, the user issues commands on the server. The user uses Telnet to terminate a Telnet command and log off.

How to Use Telnet on a Computer?
Step 1: Look for the Control Panel in the Start menu to open it. Alternately, press WIN+R to bring up the Run dialog box, then take control.
Step 2: Choose the Programs option. Select Programs and Features instead, and move on to Step 4, if you are seeing the Control Panel applet icons and can't see them. Look for Control Panel in the Start menu to open it. Alternately, press WIN+R to bring up the Run dialog box, then take control.
Step 3: Choose Features and Programs.
Step 4: From the left pane, select Turn Windows features on or off.
Step 5: Next to Telnet Client, check the box.
Step 6: To activate Telnet, select OK. You can close any active dialog boxes after you see the Windows performed the desired modifications statement.
Significant uses of Telnet
Troubleshooting Network Connectivity
Telnet still has certain uses today, having been used widely in the early days of the Internet. The following are a few common uses for this protocol: Testing connectivity to a network device or server is one way to troubleshoot network connectivity. You can determine whether the device or server is reachable, find any errors or connectivity issues, and diagnose network issues by establishing a Telnet connection to it.
Setting Up Network Devices
Routers, switches, and firewalls can all be remotely configured by network administrators via Telnet. They may make changes to the network architecture and administer the devices from a single location without having to physically access each one.
Legacy System Access
Telnet is still used to provide remote access to certain legacy computer systems. It facilitates resource management, data processing, application execution, and system connections.
Application Testing and Debugging
An application's ability to connect and communicate with a remote server or device can be tested using the protocol. Developers and testers can confirm that the program is operating successfully and troubleshoot any issues by connecting to the system using Telnet.
Remote Server Administration
A command-line interface-running server can be remotely managed with this tool. System administrators can run scripts, configure servers remotely, and carry out other operations by starting a Telnet session.
