Match List - I with List - II. (Description) (ICT Term) (A) Name of an…

Concept

Every ICT term in a matching list belongs to exactly one category: system software, a hardware component, a hardware manufacturer, or a network service.

So each description is resolved by first identifying which of these categories it is describing, and then selecting the one listed term that belongs to that category.

Application

1. "Name of an operating system" describes the system software that manages the hardware and runs applications; Android is Google's mobile operating system, so (A) pairs with (III).

2. "Name of a CPU manufacturer" describes a company that designs and fabricates processors; Intel Corporation manufactures CPUs, so (B) pairs with (IV).

3. "Links web pages" describes the system of hypertext documents joined to one another by hyperlinks; the World Wide Web (WWW) is that system, so (C) pairs with (I).

4. "Brain of Computer" describes the unit that fetches, decodes and executes instructions and carries out arithmetic and logic operations; the Central Processing Unit (CPU) does this and is conventionally called the brain of the computer, so (D) pairs with (II).

Cross-check

The four terms fall into four different categories and each term is used exactly once, so the mapping is one-to-one with no term left unmatched and none used twice.

Hence the correct matching is (A)-(III), (B)-(IV), (C)-(I), (D)-(II).
