UGC NET Questions (Paper – 1)

A search engine is a specialised information retrieval system that indexes web pages and ranks them in response to user queries. By typing keywords, users can quickly find relevant sites, documents and media from billions of resources. Algorithms evaluate relevance using factors like content, links and user behaviour. Hence the description in the stem clearly refers to a search engine.

Option A:
Option A, web browser, is a client program used to display web pages but it does not by itself search the entire web. Browsers can use search engines but their primary purpose is rendering content.

Option B:
Option B, web server, hosts websites and delivers pages to clients but does not provide keyword-based search across the web. Its role is to respond to HTTP requests rather than index external sites.

Option C:
Option C, social network, denotes platforms where users create profiles and interact socially. While they may have internal search features, they are not general tools for locating information across the whole web.

Option D:
Option D is correct because search engines are explicitly designed to respond to keyword queries with ranked lists of web resources, matching exactly what the stem describes.
