Q272. Consider the following components related to search engines:
I. Web Crawler (Spider)
II. Indexer
III. Search Algorithm
IV. User Interface
V. Web Hosting Server
Which of the above components are primarily responsible for discovering, cataloging, and ranking web pages in a search engine’s core operations?
I. Web Crawler (Spider)
II. Indexer
III. Search Algorithm
IV. User Interface
V. Web Hosting Server
Which of the above components are primarily responsible for discovering, cataloging, and ranking web pages in a search engine’s core operations?
Explanation
Search engines rely on three core processes to provide results: crawling, indexing, and ranking. Web crawlers or spiders continuously discover new and updated pages, which the indexer then catalogs in a massive database. Finally, search algorithms evaluate these indexed pages to determine their relevance and order for specific user queries. While user interfaces and servers are necessary, they are not.
Q273. Identify the incorrect statement regarding web browsers.
Explanation
Web browsers are application software, such as Chrome or Firefox, that allow users to access and display information from the World Wide Web. They function by rendering HTML and other code into visual pages. It is important to note that browsers do not host websites themselves; instead, websites are hosted on remote web servers and accessed by browsers over the internet.
Q274. When a user repeatedly visits a website and finds that their login credentials and site preferences are remembered, which web technology is primarily at play?
Explanation
Cookies are small text files stored on a user’s computer by a web browser at the request of a website. They are used to track user activity, remember login credentials, and store site preferences, providing a personalized browsing experience. By maintaining state across different sessions, cookies allow websites to recognize returning visitors and deliver customized content or maintain active shopping cart items.
Q275. Who is globally recognized as the inventor of the World Wide Web (WWW) and the HTML markup language?
Explanation
Tim Berners-Lee is the visionary computer scientist who invented the World Wide Web in 1989 while working at CERN. He developed the fundamental technologies that still power the web today, including HTML for document formatting, HTTP for data transfer, and the first web browser. His decision to keep these technologies open and royalty-free allowed the web to grow into a global platform.
Q276. Identify the odd one out among the following Internet entities.
Explanation
Google, Bing, and DuckDuckGo are search engines, which are online tools designed to help users find information on the World Wide Web by indexing and ranking pages. Mozilla Firefox, however, is a web browser, which is the application software used to access and view those web pages. This distinction between the tool that searches and the tool that displays is fundamental.
Q277. Which statement correctly distinguishes the Deep Web from the Dark Web?
Explanation
The Deep Web consists of all parts of the internet not indexed by standard search engines, including private databases, emails, and subscription-based content. The Dark Web is a small, intentional subset of the Deep Web that requires specialized software like Tor to access. While both are hidden from public search results, the Dark Web specifically focuses on anonymity and requires unique technical tools.
Q278. Given below are two statements regarding web evolution.
Statement I: Web 1.0 was characterized by static, read-only web pages.
Statement II: Web 2.0 introduced interactivity, user-generated content, and social media platforms.
Which of the above statement(s) is/are correct?
Statement I: Web 1.0 was characterized by static, read-only web pages.
Statement II: Web 2.0 introduced interactivity, user-generated content, and social media platforms.
Which of the above statement(s) is/are correct?
Explanation
The evolution of the web is marked by a shift from static to dynamic content. Web 1.0 was primarily a "read-only" environment where users consumed information from static pages. Web 2.0 transformed this into a "read-write" platform characterized by high interactivity, social media, and user-generated content. This transition empowered individuals to become creators and participants in the global digital conversation, rather than just.
Q279. Which of the following is not a core component or standard technology of the World Wide Web?
Explanation
The World Wide Web is built on a specific set of core technologies, including HTML for structuring content, HTTP for transmitting data, and URLs for locating resources. These technologies operate at the application layer to provide a unified web experience. MAC addressing, conversely, is a low-level hardware identification method used at the data link layer of a network, functioning independently of web.
Q280. What is the intended effect of applying Search Engine Optimization (SEO) strategies to a website?
Explanation
Search Engine Optimization involves implementing various strategies and techniques to improve a website’s ranking in search engine results pages. By optimizing content, keywords, and technical aspects, site owners aim to increase organic traffic and visibility to potential users. High SEO rankings ensure that a website appears more prominently when users search for related topics, directly impacting its online reach and success.Answer key for these questions

Key facts from Science and Technology
- The RPSC paper is General Knowledge and General Science, so science questions come with a strong dose of applied and recent topics.
- Everyday science questions test the laws and terms of physics, chemistry and biology through examples.
- Defence and space questions pair a missile, satellite or mission with its year and organisation.
- Policy questions ask for the year, the body and the aim of schemes like STIP, the National Quantum Mission and BioE3.
- Health, environment and agriculture are on a separate page, with their own chapters.
Frequently asked questions
How many RAS Prelims practice MCQs are there on Science and Technology?
This page has 1113 practice MCQs on Science and Technology. Each has the correct answer, and most have an explanation.
Which chapters does the science and technology set cover?
Six chapters: basics of everyday science; computers, information and communication technology; defence and space technology in India; genetics, biotechnology and nanotechnology; science and technology policies and government programmes; and recent advances, Indian contributors and indigenisation.
Is science and technology part of the RAS Prelims syllabus?
Yes. The RPSC paper is called General Knowledge and General Science, and its syllabus lists science and technology topics along with environment, health, agriculture and government programmes, so questions can come from any of these areas.
How should I prepare science for RAS Prelims?
Revise the concepts by examples, then learn the missions, schemes and scientists with their year and organisation. Attempt each chapter, read the explanations and keep a list of the facts you missed.
