Which of the following is used by news servers to distribute documents to readers?

ANetwork News Transfer Protocol (NNTP) ✓ Correct

BHypertext Transfer Protocol

CFile Transfer Protocol

DNone of the above

Correct answer: (A) Network News Transfer Protocol (NNTP)

Explanation

News servers distribute articles to readers using the Network News Transfer Protocol.

Hypertext Transfer Protocol serves web pages to browsers, not newsgroup articles between news servers.

File Transfer Protocol moves files between hosts and is not the newsgroup distribution protocol.

No other choice fits because NNTP is the correct news-distribution protocol.

NNTP handles posting and retrieving articles in Usenet newsgroups.

Usenet organises discussions into hierarchical newsgroup categories.
