Telnet, a network protocol, first opened for business in 1969. It was one of the first internet standards. It is still one of the standards used today.
when you bbming someone and you ping theit doesnt mean anything. Idt just means that the get this big loud ping and when the read it it says ping.
what is difference between communication and transport
difference between ip address and class
the difference is...
FTP and Telnet are similar in that they are defined as OSI layer 7 (application) protocols. They are different in that they use different ports for sending and receiving messages and are used for different purposes. FTP is used to sending and receiving files across a network. Telnet is used to send commands remotely to another network device.
The firewall blocks it. Almost all router have telnet port blocked because it's considered dangerous.
Telnet is a protocol for transferring plain text over TCP .
tcp
rsh and ssh are similar in that they can execute commands on remote systems. The main difference between the two (besides the actual TCP ports) is that rsh traffic is not encrypted and therefore a security risk; ssh traffic is encrypted. The other main difference is that ssh is a secure replacement for telnet, whereas rsh can log into a remote system using the rlogin protocol, which is similar but not the same as telnet.

Telnet use port number 23,and connected to TCP
If you connect to the router via the console port then you are physically making a connection with a physical cable to the router. This implies you have to be close to the router itself. Using telnet allows you to connect to the router from anywhere in the network, and doesn't require a physical cable connection.
As a metric of network performance, Ping, also known as Network Latency, is a measurement of the time that it take for a small message (or a "Ping") to be sent from your computer to another computer on the internet, then returned back to you. Ping is typically measured in milliseconds. Low numeric results or a "Low Ping" is desirable for good network performance over a "High Ping". Ping is also the name of of command-line command that can be typed to initiate a "ping" and measure the time that it takes for the message be returned to your computer.
