What is ICMP used for?

  1. Internet Control Message Protocol

  2. HyperText Transfer Protocol

  3. Post Office Protocol 3

  4. File Transfer Protocol

The correct answer is: Internet Control Message Protocol

ICMP (Internet Control Message Protocol) is used for error reporting and diagnostic purposes. Option B, HyperText Transfer Protocol, is used for transferring data between a web server and a web browser. This is not the intended purpose of ICMP. Option C, Post Office Protocol 3, is used for accessing email messages from a remote server. This is also not the intended purpose of ICMP. Option D, File Transfer Protocol, is used for transferring files over a network. Again, this is not the intended purpose of ICMP.
