Which of the following is a protocol?
Correct answer: D. All of these
- A. FTP
- B. Ethernet
- C. ARCnet
- D. All of these
Explanation
● FTP (File Transfer Protocol): This is a set of rules that govern how files are transferred between computers on a network.● Ethernet: This is a type of networking technology that defines how data is transmitted over cables. It is not a protocol itself, but it relies on protocols like TCP/IP to function.● ARCnet (Attached Resource Computer Network): This is a type of networking technology that was once popular for LANs (Local Area Networks). Similar to Ethernet, it relies on protocols to function.Explanation of Incorrect Options:Ethernet and ARCnet are networking technologies, they define how data is physically transmitted over a network. Protocols, on the other hand, define how data is formatted and transmitted between devices. They act as a common language for communication
