Internet protocols overview – UGC NET Question

Statements A, B and C are correct descriptions of HTTP, FTP and SMTP, whereas statement D is clearly wrong. TCP/IP is a suite of communication protocols used for data transmission over networks, not for offline storage on a hard disk. It provides the foundation for Internet and many network operations. Hence, the combination that selects only statement D as wrong is the correct answer.

Option A:
Option A is incorrect because it treats both A and D as wrong statements. Statement A correctly explains that HTTP is used for transferring web pages and related resources. Including a true statement in the wrong set makes this option invalid.

Option B:
Option B is incorrect because it groups C and D as wrong statements. While D is wrong, C is correct in describing SMTP as a protocol for sending email between servers. Mixing a correct statement with an incorrect one means this option cannot be the right answer.

Option C:
Option C is incorrect because it contains A, B and D as wrong statements. Both A and B are accurate descriptions of HTTP and FTP, so they should not be labelled wrong. Including true statements in the wrong set contradicts the actual meanings of the protocols.

Option D:
Option D is correct because it isolates D as the only wrong statement. It recognises that TCP/IP is used for network communication rather than offline storage. By acknowledging A, B and C as correct, this option matches the intention of the question.
