Step 1: Understanding the Concept:
Internet application layer network protocols: File Transfer Protocol (FTP RFC 959) is the client-server protocol specifically designed for downloading and uploading bulk binary/text files across TCP/IP networks.
Step 2: Detailed Explanation:
Application layer internet network communication protocols:
1. FTP (File Transfer Protocol) (C): A standard communication protocol operating over TCP (ports 20/21) specifically engineered for transferring, downloading, and uploading computer files between a client and a remote server on the Internet.
2. HTTP (Hypertext Transfer Protocol): Protocol for transferring web pages/hypertext over the World Wide Web.
3. TELNET: Protocol for remote terminal command-line text access.
4. UTP: Unshielded Twisted Pair (physical copper network cable type).
Step 3: Final Answer:
Therefore, a user gets files from another computer by using FTP, corresponding to option (C).
