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.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.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.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.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.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.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.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.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 Computers, Information and Communication Technology
- First-generation computers used vacuum tubes; the second generation moved to transistors.
- Analog computers work on continuous variable data rather than discrete binary data.
- The Control Unit directs and coordinates the operations of the CPU.
- Cache memory gives the fastest access to the CPU; the hierarchy from fastest to slowest is registers, cache, RAM and magnetic disk.
- Adding more RAM to a system with many page faults reduces its dependence on virtual memory.
- An SSD differs from an HDD by the use of NAND flash memory.
Frequently asked questions
How many RAS Prelims practice MCQs are there on Computers, Information and Communication Technology?
This page has 200 practice MCQs on Computers, Information and Communication Technology (Science and Technology). Each has the correct answer, and most have an explanation.
What was used in first-generation computers?
Vacuum tubes. They were large, used much power and produced heat. The second generation replaced them with transistors, which were smaller, faster and more reliable, and later generations moved to integrated circuits and microprocessors.
Which memory is fastest for the CPU?
Cache memory, apart from the registers inside the CPU. The memory hierarchy from fastest to slowest is registers, cache, RAM and magnetic disk, and capacity increases as speed falls.
How does an SSD differ from an HDD?
An SSD stores data in NAND flash memory with no moving parts, while a hard disk drive uses spinning magnetic platters. As a result an SSD is faster, quieter and more resistant to shock.
