Show answer & explanation
Correct answer: C
Concept
Internet keywords are told apart by the job each one performs, not by the broad topic they share. Some of these terms are protocols, that is, rule sets governing an exchange between two machines, so what separates one protocol from another is what it is defined to carry. Another is a markup language, a notation that describes the structure and content of a document rather than moving anything. Another is a diagnostic utility, a small command whose job is to probe a remote host and report what comes back.
So the method is: first ask whether a keyword carries data, describes a document, or probes a link; then, for the ones that carry data, ask what kind of data each is defined to carry.
Application
Keyword | Job it performs | What it does |
|---|---|---|
FTP (File Transfer Protocol) | File-transfer protocol, together with the client program that speaks it | Moves files from one computer to another |
Ping | Diagnostic utility that sends an ICMP echo request | Probes a remote host and reports the echo reply and the round-trip time |
HTML (HyperText Markup Language) | Markup language | Creates hypertext documents for use on the web |
HTTP (HyperText Transfer Protocol) | Application-layer protocol | Sets the rules by which documents are requested and exchanged on the web |
Reading each row against LIST-II gives: FTP takes IV, Ping takes II, HTML takes I and HTTP takes III.
Cross-check
HTML and HTTP share the HyperText prefix but differ in kind: HTML is the language a page is written in, whereas HTTP is the protocol that carries that page from a server to a browser. A description worded as a set of rules to exchange documents names a protocol, so it cannot describe a language.
FTP and HTTP are both protocols, so the wording that separates them is what each is defined to carry: FTP is specified for moving files between two computers, while HTTP is specified for requesting and exchanging documents over the web.
Ping neither carries a document nor defines a document format. It sends one ICMP echo request and reports the reply along with the round-trip time, which is why it is described here as a message sent to check whether a server is running. Strictly, that reply shows the host answers ICMP; it does not by itself prove a particular server application is up.
The expansions confirm the reading: File Transfer Protocol, HyperText Markup Language and HyperText Transfer Protocol.
Hence the correct pairing is A-IV, B-II, C-I, D-III.
