1
What does the term “Internet” stand for?
Explanation: The Internet is called an Interconnected Network because it links millions of individual computer networks across the world together. These networks use a common set of protocols (TCP/IP) to share data seamlessly. It is not limited to one country (so “International” is misleading), nor is it private like an “Internal” network. The word itself is a shortened form of “inter-networking.”
2
Which of the following is NOT a use of the Internet?
Explanation: The Internet is a digital tool; it cannot perform physical tasks such as cooking food. Its genuine uses include communication via email, shopping on e-commerce platforms, watching videos, video conferencing, research, and much more. Physical actions like cooking require real-world appliances and human effort, which are entirely outside the scope of what any digital network can do.
3
An Intranet is best described as a network that is:
Explanation: An Intranet is a private internal network designed for use within a specific organization — such as a company, school, or hospital. Only authorized employees or members can access it. Unlike the Internet, which is public and global, an Intranet keeps sensitive data secure and helps staff collaborate efficiently without exposing information to outsiders.
4
Which one of these is the key difference between the Internet and an Intranet?
Explanation: The fundamental difference lies in accessibility. The Internet is a publicly accessible global network that anyone with a connection can use. An Intranet, on the other hand, is a private network restricted to a specific group such as a company’s employees. Speed and hardware requirements are not defining differences; access control is the core distinction between them.
5
Which type of website provides study materials, e-books, and online courses?
Explanation: Educational websites focus on delivering learning content to students, teachers, and self-learners. They offer resources such as video lectures, e-books, practice tests, study notes, and online courses. Examples include Khan Academy and National Geographic Education. Commercial websites sell products; social media connects people; news websites report current events — none of these share the primary educational mission.
6
Which of the following is a well-known example of an educational website?
Explanation: Khan Academy is a globally recognized educational website that offers free courses in mathematics, science, history, and other subjects for students of all ages. It uses videos, exercises, and quizzes to reinforce learning. Amazon and eBay are commercial/e-commerce platforms built for buying and selling, while Instagram is a social media platform focused on photo and video sharing.
7
A commercial website primarily aims to:
Explanation: Commercial websites exist to generate revenue by offering products or services to customers online. They feature product catalogues, shopping carts, payment gateways, and customer support systems. Famous examples include Amazon, Flipkart, and Alibaba. These websites focus on business transactions, unlike educational sites that teach, or social media platforms that prioritize user interaction and content sharing.
8
Which of the following websites is an example of a commercial website?
Explanation: Amazon is one of the world’s largest commercial websites. It sells millions of products ranging from electronics to groceries and also offers paid services such as Amazon Prime. Wikipedia is an open encyclopedia (informational), Twitter is a social media platform for microblogging, and Khan Academy is an educational website. Each serves a fundamentally different purpose from commercial selling.
9
Social media websites primarily allow users to:
Explanation: Social media websites are digital platforms designed for human interaction. They allow users to create profiles, share text posts, photos, videos, and links, comment on others’ content, and build communities. They are communication-first environments. While some have added shopping features, their core purpose has always been social connectivity and content sharing among people worldwide.
10
Which of the following is an example of a social media website?
Explanation: Facebook is one of the largest and most recognizable social media platforms in the world. It allows users to post status updates, share multimedia, join groups, create events, and message friends. Google Drive is a cloud storage service, Microsoft Word Online is a word-processing tool, and PayPal is a digital payment service — none of these are social media platforms.
11
What is a web browser?
Explanation: A web browser is a software application installed on a computer or mobile device that requests, retrieves, and visually displays web pages from the World Wide Web. It interprets HTML, CSS, and JavaScript to render readable pages. Browsers do not store all website data or physically connect devices — that is the role of modems and routers. Search engines are separate tools, often embedded within browsers.
12
Which of the following is NOT a web browser?
Explanation: Microsoft Excel is a spreadsheet application used for data entry, calculations, and creating charts — it has nothing to do with browsing the web. Google Chrome, Mozilla Firefox, and Safari are all genuine web browsers that allow users to access websites on the Internet. Each browser interprets web code and presents content visually to the user on screen.
13
To open a specific website, you type its address in the browser’s:
Explanation: The address bar, also called the URL bar or omnibar, is the input field at the top of every web browser where you type a website’s Uniform Resource Locator (URL). After typing the address and pressing Enter, the browser contacts the web server and loads the requested page. The bookmark panel saves favourite pages, the download manager manages file downloads, and the history tab shows previously visited pages.
14
A URL typically begins with which of the following?
Explanation: Most modern websites use HTTPS (HyperText Transfer Protocol Secure) at the start of their URL. The “S” indicates the connection is encrypted for security. While FTP is used for transferring files between computers, it is not the standard for everyday web browsing. “mail://” and “web://” are not standard URL protocols. HTTPS has become the universal standard for secure, trusted web browsing.
15
What is a search engine used for?
Explanation: A search engine is an online tool that allows users to type keywords or phrases and find relevant web pages, images, videos, or documents from across the Internet. It uses automated programs called “crawlers” or “bots” to index websites. Google, Bing, and Yahoo are popular examples. Search engines do not create websites, send emails, or provide cloud storage — these are separate internet services.
16
Which of the following is the most widely used search engine in the world?
Explanation: Google consistently holds the title of the world’s most widely used search engine, processing billions of search queries every day. Its powerful ranking algorithm, speed, and accuracy have made it dominant globally. Yahoo was once a major player but lost its lead over time. Bing, owned by Microsoft, and DuckDuckGo, known for privacy, are used by smaller audiences compared to Google.
17
What information do you need to create an email account?
Explanation: Creating an email account on platforms like Gmail or Outlook requires only basic information — a desired username (which becomes the email address), a secure password, and some personal details such as your name and sometimes a recovery phone number. No credit card, passport, or physical address is required for a standard free email account, making email accessible to virtually everyone with Internet access.
18
Which of the following is a valid use of email?
Explanation: Email is an electronic messaging service that allows users to send text messages, files, images, and documents to one or more recipients anywhere in the world instantly. Sending a document to a colleague is a classic, everyday use of email in professional settings. Video editing, running antivirus tools, and installing hardware are tasks performed using dedicated software and physical tools — not email services.
19
Which part of an email address comes after the “@” symbol?
Explanation: An email address has two parts separated by the “@” symbol. The part before “@” is the unique username chosen by the account holder. The part after “@” is the domain name of the email service provider — for example, “gmail.com” or “yahoo.com.” The subject line and password are separate parts of the email interface, not components of the actual email address format.
20
Which browser was developed by Apple specifically for its devices?
Explanation: Safari is a web browser created and maintained by Apple Inc. It is the default browser on all Apple devices including iPhone, iPad, and Mac computers. Apple designed Safari to integrate tightly with its hardware and software ecosystem, offering speed and energy efficiency. Opera is developed by Opera Software, Firefox by Mozilla, and Microsoft Edge by Microsoft — none of these are Apple products.

21
What does “WWW” stand for in a website address?
Explanation: “WWW” stands for the World Wide Web — a system of interlinked hypertext documents and multimedia content that you access via the Internet using a web browser. Tim Berners-Lee invented the World Wide Web in 1989. It is important to note that the Internet and the World Wide Web are not the same thing; the Web is one of many services that runs on top of the Internet infrastructure.
22
What is one major advantage of social media for users?
Explanation: One of the greatest advantages of social media is its ability to connect people instantly regardless of geographic distance. A person in one country can communicate with someone on the other side of the world in real time through messages, video calls, or posts. Social media does not guarantee privacy (quite the opposite), does not prevent misinformation, and certainly has no effect on physical fitness.
23
Which of the following is a disadvantage of using social media?
Explanation: Social media has well-documented disadvantages including cyberbullying, online harassment, addiction, anxiety, and exposure to false information. The anonymous nature of the Internet can encourage harmful behavior. Excessive use also reduces productivity and disrupts sleep patterns. While social media does have positive uses like sharing news and video calls, these are advantages — not disadvantages. The question specifically asks for a negative aspect.
24
What does the term “network” mean in computing?
Explanation: In computing, a network is a group of two or more computers or devices connected together — either by cables or wirelessly — so they can communicate and share resources such as files, printers, and internet connections. Networks vary in size from small home setups (LAN) to large corporate systems (WAN). A single standalone computer, no matter how powerful, does not constitute a network.
25
Which of the following is a use of computer networks?
Explanation: One of the most practical uses of a computer network is resource sharing — for example, multiple computers in an office can all share one network printer instead of requiring each machine to have its own. Networks also enable file sharing, internet access sharing, and centralized data storage. Playing a DVD, charging a phone, or using a typewriter are standalone activities that require no network connectivity.
26
The Internet originally started as a project by which organization?
Explanation: The Internet grew from ARPANET, a project funded by the U.S. Department of Defense’s Advanced Research Projects Agency (ARPA) in the 1960s. ARPANET was designed to allow researchers to share data and communicate even if part of the network was destroyed. NASA is a space agency, WHO deals with global health, and Microsoft is a private technology company — none of them originated the Internet.
27
Which protocol does the Internet primarily use to transmit data?
Explanation: TCP/IP (Transmission Control Protocol / Internet Protocol) is the foundational set of communication rules the Internet uses to send and receive data. TCP breaks data into packets, and IP ensures each packet reaches the correct destination. USB and Bluetooth are short-range data transfer technologies for connecting devices locally, not for global network communication. Wi-Fi is a wireless networking standard, not a transmission protocol at the Internet level.
28
What is the purpose of the “Refresh” or “Reload” button in a browser?
Explanation: The Refresh or Reload button in a browser sends a fresh request to the web server to re-fetch and re-display the current page. This is useful when a page fails to load correctly, content has not updated, or a connection error occurred. It does not close the tab, translate content, or permanently alter browser speed. It simply fetches the latest version of the current page from its server.
29
Which of the following is an example of a search engine other than Google?
Explanation: Bing is a search engine developed and operated by Microsoft. It indexes the web and allows users to search for websites, images, videos, and news. Wikipedia is an online encyclopedia, YouTube is a video-sharing platform, and WhatsApp is a messaging application — none of them are search engines that crawl and index the broader web to answer general queries the way Bing or Google do.
30
What does “CC” stand for in an email?
Explanation: “CC” in email stands for Carbon Copy — a term borrowed from the old practice of placing carbon paper between sheets to create duplicate documents. In email, adding a recipient to the CC field sends them a copy of the message; all recipients can see who was CC’d. The related field “BCC” (Blind Carbon Copy) hides recipients from each other. These fields help keep multiple people informed simultaneously.
31
Which social media platform is primarily known for sharing short video clips?
Explanation: TikTok is a social media platform owned by ByteDance that specializes in short-form video content, typically ranging from 15 seconds to several minutes. It gained massive popularity for its entertainment, trends, and algorithm-driven feed. LinkedIn is a professional networking site, Pinterest focuses on visual bookmarking and ideas, and Reddit is a forum-based platform for discussions and communities — each with a distinct purpose from TikTok.
32
An Intranet helps employees of a company to:
Explanation: A company Intranet serves as a private digital workspace for employees. It allows secure sharing of internal reports, policies, notices, and project files without risking exposure to outside parties. Teams can collaborate on documents, access company databases, and communicate through internal messaging tools. Online shopping, social media, and entertainment downloads are external Internet activities that an Intranet is specifically designed to separate from.
33
What is the main purpose of a hyperlink on a webpage?
Explanation: A hyperlink is clickable text or an image on a web page that, when clicked, directs the user to another web page, a section of the same page, a file, or another online resource. Hyperlinks form the foundation of web navigation and are what make the World Wide Web an interconnected system. They do not carry advertisements, affect loading speed, or store passwords — those are handled by different web technologies.
34
Which of the following best describes an IP address?
Explanation: An IP (Internet Protocol) address is a unique numerical identifier assigned to every device connected to a network. It works like a postal address, allowing data packets to find the correct device. IPv4 addresses look like “192.168.1.1” while newer IPv6 addresses are longer. IP addresses are essential for routing information across the Internet. They have nothing to do with viruses, email passwords, or browser extensions.
35
Social media can assist businesses by:
Explanation: Businesses widely use social media as a digital marketing tool to reach large and targeted audiences. Platforms like Instagram, Facebook, and LinkedIn allow companies to showcase products, run advertisements, engage with customers, and build brand loyalty at a relatively low cost. Social media cannot reduce electricity consumption, fully replace human customer service in all situations, or perform legal and financial tasks like tax filing.
36
What is “spam” in the context of email?
Explanation: Spam refers to unwanted, unsolicited emails typically sent in bulk to thousands of recipients. Spam emails often contain advertisements, phishing attempts, scams, or malware links. Email providers use spam filters to automatically move these messages to a “Spam” or “Junk” folder. Spam is different from a regular group email, an email with attachments, or an important message folder — it is specifically unwanted mass communication sent without the recipient’s consent.
37
Mozilla Firefox is developed and maintained by:
Explanation: Mozilla Firefox is an open-source web browser developed by the Mozilla Foundation, a non-profit organization dedicated to promoting an open and accessible Internet. Firefox is well known for its strong emphasis on user privacy and customizability. Google developed Chrome, Apple developed Safari, and Microsoft developed Edge (and previously Internet Explorer). Each browser reflects the values and priorities of its respective developer organization.
38
Which of the following correctly describes a “homepage” of a website?
Explanation: A homepage is the main landing page of a website — the first page visitors typically see when they type the website’s domain name (e.g., www.example.com) without specifying any sub-page. It usually contains navigation menus, an overview of the site’s purpose, and links to other sections. It is not the last page visited, an email inbox, or a cached local copy of a page.
39
Which of the following statements about networks is TRUE?
Explanation: Computer networks are not limited by physical proximity. A Local Area Network (LAN) may cover just one room or building, a Wide Area Network (WAN) spans cities or countries, and the Internet is a global network connecting billions of devices. Networks can be wired or wireless and can consist of just two computers. There is no minimum requirement of 100 computers — even two devices form a basic network.
40
What is the correct first step to access a website using a browser?
Explanation: To open a web page, the user must first launch a web browser (such as Chrome or Firefox) and then type the website’s URL into the address bar at the top of the browser window. Pressing Enter sends a request to the web server, which responds by sending the page content back to the browser for display. Opening an email, restarting the computer, or connecting a USB drive are unrelated steps that do not help access a specific website.

41
What does “downloading” mean in the context of the Internet?
Explanation: Downloading refers to the process of transferring data — such as files, music, images, or videos — from a remote server on the Internet to your local device (computer, phone, or tablet). The opposite process is “uploading,” which means sending data from your device to the Internet. Downloading has nothing to do with deleting files locally or connecting hardware devices like printers, which are performed differently.
42
Which of the following is an advantage of using email over traditional postal mail?
Explanation: Email’s biggest advantages over traditional postal mail are speed and cost. An email reaches its recipient within seconds, anywhere in the world, at no direct cost. Traditional mail takes days or weeks and costs money per item sent. Email cannot deliver physical packages. It also does not require postage stamps, and modern email is accessible from smartphones, tablets, laptops, and desktops — not just desktop computers.
43
What is cyberbullying?
Explanation: Cyberbullying is the use of digital technologies — including social media, messaging apps, online forums, and email — to deliberately harass, threaten, embarrass, or target another person. It is a serious problem particularly among young people. Cyberbullying differs from hacking (which is unauthorized system access) and has no relation to playing video games or fixing computers. It is a form of online abuse that can cause significant psychological harm.
44
Which of the following is an example of networking helping in education?
Explanation: Computer networking enables students to connect to online learning platforms, attend live video lectures, access digital libraries, and submit assignments electronically — all from their homes or any location with Internet access. This has been particularly important during events like the COVID-19 pandemic. Writing in notebooks and reading printed textbooks are offline activities that exist entirely outside the scope of networking technology.
45
Instagram is primarily a platform for sharing:
Explanation: Instagram, owned by Meta, is a visual social media platform built around sharing photographs, short videos, Reels (vertical short-form videos), and Stories (temporary 24-hour posts). It is popular among individuals, influencers, and brands who rely on visual storytelling. Spreadsheets are shared via productivity tools like Google Sheets, academic articles on platforms like ResearchGate, and source code on GitHub — each of which serves a very different audience and purpose.
46
What is the role of a web server?
Explanation: A web server is a computer or software system that stores website files (HTML pages, images, videos, etc.) and serves them to users when their browsers make a request. When you type a URL, your browser contacts the web server hosting that site, which then sends back the page files. Web servers do not print documents, scan for viruses, or regulate internet connection speeds — those functions belong to other technologies.
47
Which of the following is a privacy-focused search engine?
Explanation: DuckDuckGo is a search engine specifically designed to protect user privacy. Unlike Google, Bing, or Yahoo, it does not track users’ search history, create personal profiles, or sell targeted advertising based on behavior. It has gained popularity among users who value anonymity online. Google and Bing personalize search results using data collected about users, while DuckDuckGo deliberately avoids such data collection practices entirely.
48
What is the meaning of “uploading” on the Internet?
Explanation: Uploading is the process of transferring data — such as photos, documents, or videos — from your local device to a remote server on the Internet. Examples include posting a photo on Instagram, submitting a file through Google Drive, or publishing a video on YouTube. The opposite action is downloading (fetching data from a server). Refreshing a browser and saving to a USB drive do not involve sending data to an Internet server.
49
What does “ISP” stand for?
Explanation: ISP stands for Internet Service Provider — a company that provides individuals and organizations with access to the Internet. Examples include Airtel, Jio, AT&T, and Comcast. ISPs manage the physical and wireless infrastructure that carries data between homes, businesses, and the broader Internet. Without an ISP, a home computer cannot connect to the Internet, no matter how many browsers or devices are available.
50
Which of the following describes a LAN?
Explanation: LAN stands for Local Area Network. It connects computers and devices within a limited geographical area such as a single building, school, office, or home. LANs typically offer high data transfer speeds and low latency. A WAN (Wide Area Network) connects across cities or countries, and the Internet is the largest global network. LANs do not rely exclusively on satellite connections — most commonly they use Ethernet cables or Wi-Fi.
51
Which social media platform is most popular among working professionals for networking?
Explanation: LinkedIn is a professional social networking platform specifically designed to help people connect with colleagues, employers, and industry peers. Users post resumes, share work achievements, job openings, and industry insights. It is widely used for career development and B2B marketing. Snapchat and TikTok are entertainment-focused platforms aimed at younger audiences, while Pinterest is a visual idea-sharing board — none primarily serve the professional networking space like LinkedIn does.
52
What is “phishing” in the context of the Internet?
Explanation: Phishing is a type of cybercrime where attackers send fraudulent emails, messages, or create fake websites designed to look legitimate in order to trick users into revealing sensitive information such as passwords, credit card numbers, or bank account details. The term comes from “fishing” for information. It is one of the most common forms of online fraud and is entirely unrelated to internet speed improvement, gaming, or spam filtering tools.
53
What is a “cookie” in web browsing?
Explanation: In web browsing, a cookie is a small text file that a website stores on a user’s device through the browser. Cookies help websites remember user preferences, login sessions, shopping cart contents, and personalization settings. They are not harmful by nature, unlike malware. They are also not browser updates or programming languages. However, tracking cookies raise privacy concerns because they monitor user behavior across different websites.
54
What does “streaming” mean in Internet terms?
Explanation: Streaming allows users to watch videos, listen to music, or play games in real time through their Internet connection without needing to wait for a full download. Platforms like Netflix, YouTube, and Spotify use streaming technology. The content plays as data arrives continuously. This is fundamentally different from downloading (where the whole file is saved first), printing, or local data backup processes, which don’t require active Internet playback.
55
Which of the following best describes a WAN?
Explanation: WAN stands for Wide Area Network. It connects computers and networks over very large geographical distances — spanning cities, countries, or even continents. The Internet itself is the world’s largest WAN. Businesses use private WANs to connect branch offices in different cities. A LAN covers a small area like one building or floor. A smartphone hotspot creates a miniature local network. A hospital network would typically be a LAN or MAN (Metropolitan Area Network).
56
What does the “S” in HTTPS stand for?
Explanation: HTTPS stands for HyperText Transfer Protocol Secure. The “S” indicates that the connection between the user’s browser and the web server is encrypted using SSL/TLS technology, protecting data from being intercepted by third parties. When a website uses HTTPS, users can see a padlock icon in the browser’s address bar. Secure HTTPS connections are especially important for online banking, shopping, and login pages where sensitive data is transmitted.
57
Twitter (now X) is best known as a platform for:
Explanation: Twitter, rebranded as X by Elon Musk, built its reputation as a microblogging platform where users post short messages called “tweets.” It became a major hub for real-time news, trending topics, public discourse, and commentary from journalists, politicians, celebrities, and everyday users. It is not designed for editing spreadsheets, selling products (like e-commerce platforms), or streaming long-form video content (like Netflix or YouTube).
58
What is the function of a router in a network?
Explanation: A router is a networking device that receives data packets from one network or device and forwards them to the correct destination across networks. In a home setting, a router connects your local devices (phones, laptops) to the Internet via your ISP. It acts as a traffic director for data. Routers do not permanently store websites, create email addresses, or print documents — those are functions of servers, email providers, and printers respectively.
59
Which of the following is a disadvantage of the Internet?
Explanation: While the Internet offers enormous benefits, it also poses serious risks including privacy breaches, data theft, phishing scams, cyberbullying, identity fraud, and exposure to inappropriate content. Users must be cautious about the personal information they share online. Global communication, access to information, and online banking are clear advantages of the Internet — the question specifically asks for a disadvantage, which is the exposure to online threats and privacy vulnerabilities.
60
Which of the following is used to measure internet speed?
Explanation: Internet connection speed is measured in Megabits per second (Mbps) or Gigabits per second (Gbps). This tells you how quickly data transfers between your device and the Internet. Megapixels measure image resolution in cameras, kilowatts measure electrical power consumption, and gigahertz (GHz) measures a processor’s clock speed. When you see “100 Mbps broadband,” it means your connection can transfer 100 megabits of data every second under ideal conditions.
