Knowledge Booster:
• FTP (File Transfer Protocol): FTP is used to transfer files between computers on a network. It does not support remote login for command execution.
• UDP (User Datagram Protocol): UDP is a transport layer protocol used for fast but unreliable data transmission, commonly for streaming. It does not handle remote login.
• RARP (Reverse Address Resolution Protocol): RARP is used to map a physical MAC address to an IP address in a local area network. It is not used for remote login purposes.
