1. What is the global network that connects computers worldwide for communication?

Explanation

The Internet is a worldwide system of interconnected computer networks that use standardized communication protocols to link devices globally. It allows data transfer across continents in milliseconds using TCP/IP protocols. Unlike Ethernet, which is a local networking technology, or the World Wide Web, which is a service running on it, the Internet forms the foundational infrastructure enabling global connectivity and digital communication between billions of devices simultaneously.

2. Which system links documents using hypertext and is accessed through the Internet?

Explanation

The World Wide Web is an information system built on top of the Internet that uses hypertext to connect documents. These documents are linked through URLs and accessed using HTTP or HTTPS protocols. While the Internet provides the infrastructure, the Web enables navigation between interlinked pages. It allows users to retrieve multimedia content efficiently by moving from one document to another through clickable hyperlinks.

Submit

3. Which tool finds websites based on user-entered keywords?

Explanation

A search engine is designed to locate information by scanning indexed databases based on user keywords. It uses algorithms to rank pages by relevance, authority, and accuracy. Unlike browsers that display content, search engines analyze billions of pages to return the most appropriate results within seconds. This process involves crawling, indexing, and ranking to ensure users quickly find relevant websites.

Submit

4. What do you call someone who gains unauthorized access to systems?

Explanation

A hacker is an individual who attempts to gain unauthorized access to computer systems or networks. This access may exploit security vulnerabilities through coding techniques or phishing schemes. While some hackers operate ethically for testing purposes, malicious hackers aim to steal data or disrupt systems. Their activities often involve bypassing authentication controls and exploiting software weaknesses for unauthorized entry.

Submit

5. What protects a network by monitoring incoming and outgoing traffic?

Explanation

A firewall is a security system that monitors and filters incoming and outgoing network traffic based on predefined rules. It acts as a barrier between trusted internal networks and untrusted external sources. By inspecting data packets, it blocks unauthorized access attempts. Firewalls reduce cyber threats by preventing malicious traffic from entering systems, thereby strengthening network defense mechanisms.

Submit

6. Which program protects computers from malicious software?

Explanation

Antivirus software detects, prevents, and removes malicious programs using signature-based and behavior-based detection methods. It scans files and system activities to identify suspicious patterns. Unlike firewalls that filter traffic, antivirus programs focus on eliminating harmful code within systems. Regular updates ensure protection against newly emerging threats, reducing system vulnerability and maintaining operational integrity across devices.

Submit

7. Which software allows users to access and navigate websites?

Explanation

A web browser is application software designed to retrieve, interpret, and display web content. It communicates with servers using HTTP or HTTPS protocols to fetch webpages. Browsers render HTML, CSS, and JavaScript to visually present content. Unlike antivirus or word processors, browsers specifically facilitate web navigation. Examples include Chrome and Firefox, which translate coded web data into readable and interactive digital pages.

Submit

8. Which network connects devices within a limited area like a building?

Explanation

A Local Area Network connects devices within a limited geographic area such as an office or school. It enables high-speed data sharing using Ethernet cables or wireless signals. Unlike the Internet, which spans globally, a LAN operates within confined boundaries. It improves internal communication efficiency and resource sharing, including printers and servers, while maintaining localized network control.

Submit

9. Which network is private and used within an organization?

Explanation

An intranet is a private network that operates within an organization using Internet technologies like TCP/IP and web browsers. It restricts access to internal employees, improving secure communication and collaboration. Unlike the public Internet, it limits visibility and data sharing externally. Organizations use intranets for sharing policies, internal announcements, and company resources while maintaining controlled access and data protection.

Submit

10. What extends an intranet to authorized external users?

Explanation

An extranet is an extension of an intranet that allows controlled access to authorized external users such as partners or vendors. It uses encryption and authentication protocols to maintain security. Businesses use extranets to share selective data like supply chain updates or project documents. Unlike a VPN, which secures connections, an extranet provides structured external collaboration through limited network access permissions.

Submit

11. What stores small pieces of data to identify returning users?

Explanation

Cookies are small data files stored by a web browser after receiving them from a server. They help websites recognize returning users by storing session IDs and preferences. Each time the browser reconnects, the cookie is sent back to the server, enabling personalization and tracking. Unlike cache, which stores page resources for speed, cookies primarily manage identification and session continuity.

Submit

12. Which malware can replicate itself and damage systems?

Explanation

A virus is malicious software that attaches itself to legitimate programs and replicates when executed. It spreads by infecting files or systems, potentially corrupting data or degrading performance. Unlike worms, which spread independently, viruses require user action to activate. Their replication mechanism enables exponential spread, increasing system vulnerability and causing data destruction if not detected by antivirus protection.
