Telnet, FTP, and TFTP

 Telnet is used for terminal emulation that runs programs remotely.

 Telnet uses TCP/IP protocol.

Telnet requires a username and password to access.

 FTP (File Transfer Protocol) is a connection oriented protocol. It

 uses TCP/IP for file transfer.

Compare this with TFTP (Trivial File Transfer Protocol) that uses

UDP (Connectionless protocol). SNMP uses UDP over IP.

Tracert, Ping uses ICMP as their base protocol. FTP is used to

transfer files.

Both FTP and Telnet are client-server protocols. Note that TCP/IP is a client server oriented protocol.
