Basic Computer: Internet & WWW MCQ — 15 Practice Questions with Answers

Explanation

A browser such as Chrome, Edge or Firefox is client software used to request, receive and display web pages. So Statement 1 is correct. F5 is the standard refresh key in mainstream browsers, so Statement 2 is also correct. Statement 3 adds an unrelated networking function. IP addresses are assigned through network configuration and services such as DHCP, not by the browser. Therefore, only Statements 1 and 2 are correct.

Explanation

The Internet is the underlying global network that connects computers, servers and smaller networks. The World Wide Web is not the whole Internet; it is a service that uses the Internet to access interlinked web pages through browsers. The stem asks for a distinction, so the correct option must keep the larger network and the web-page system separate. Email, file transfer and other services can also use the Internet. Hence option B states the standard relationship accurately.

Explanation

The assertion is about safety while sending login details. HTTPS means that HTTP is being used with a security layer that encrypts the communication between the browser and the web server. This does not guarantee that every website is honest, but it does protect data in transit better than plain HTTP. The reason states exactly this encryption point, so both the assertion and the reason are true, and the reason correctly explains the assertion.

Explanation

DNS stands for Domain Name System and translates human-readable domain names into IP addresses used by computers. A browser such as Chrome or Edge opens and displays web pages. A hyperlink is a clickable connection that takes the user to another page, file or resource. A search engine finds web pages after the user enters keywords. Matching these functions gives I-2, II-1, III-3 and IV-4. This is why option A is the only fully correct sequence.

Explanation

A web browser, such as Chrome or Edge, is used to display web pages. A search engine helps users search for information available on the Web. An Internet service provider supplies Internet connectivity to customers through broadband, fibre, mobile data, or similar services. An IP address is the numeric address used to identify a device on a network. Therefore the correct matching is I-2, II-1, III-3 and IV-4.
