Identifying Software: Web Browsers Explained
This question asks us to identify which option from the list is not a web browser. Let's understand what a web browser is first.
A web browser is a software application used to access, retrieve, and view information resources on the World Wide Web. These resources are typically identified by a Uniform Resource Identifier (URI) and can be web pages, images, videos, and other forms of content. Common examples include Chrome, Firefox, Safari, Edge, and Opera.
Now let's examine each option provided:
- Internet Explorer: This was a graphical web browser developed by Microsoft. It was the default browser on Windows operating systems for many years. Although largely replaced by Microsoft Edge, it is historically recognized as a web browser.
- Mozilla Firefox: This is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. It is a very popular web browser known for its flexibility and privacy features.
- Google Chrome: This is a free web browser developed by Google. It is currently the most widely used web browser globally, known for its speed and integration with Google services.
- Yahoo: Yahoo is a company that offers various internet services. While it has a popular search engine and provides services like email, news, and finance, Yahoo itself is not a web browser. It is a web portal and a search engine service that you typically access *using* a web browser.
Based on this analysis, Internet Explorer, Mozilla Firefox, and Google Chrome are all types of web browsers. Yahoo, however, is a search engine and web portal service.
Therefore, Yahoo is not a web browser.
Revision Table: Understanding Web Browsers vs. Other Internet Services
| Term | Description | Is it a Web Browser? |
|---|---|---|
| Internet Explorer | Older Microsoft software to view websites. | Yes |
| Mozilla Firefox | Popular open-source software to view websites. | Yes |
| Google Chrome | Most popular Google software to view websites. | Yes |
| Yahoo | A company providing search engine and web portal services. | No |
Additional Information on Web Browsers and Related Concepts
Understanding the difference between a web browser, a search engine, and a website is fundamental to using the internet.
- Web Browser: Your gateway to the internet. It's the application you open (like Chrome, Firefox, Edge) to type in web addresses or search queries.
- Website: A collection of related web pages, multimedia content, etc., identified by a common domain name (like google.com, yahoo.com, wikipedia.org). Websites are viewed *through* a web browser.
- Search Engine: A tool or a website (like Google, Bing, DuckDuckGo, Yahoo Search) that allows you to search for information on the World Wide Web. You access a search engine *using* a web browser, usually by typing its address or by using the browser's built-in search bar. When you search, the search engine provides a list of links to relevant websites, which you then open in your web browser.
So, while Yahoo provides a search engine and a website (yahoo.com), the Yahoo *software* itself is not a program you use to *browse* the internet; you use a browser to go to Yahoo's website to use their services.

A stone is thrown horizontally from the top of a 20 m high building with a speed of 12 m/s. It hits the ground at a distance R from the building. Taking g = 10 m/s2 and neglecting air resistance will give :
A sphere of volume V is made of a material with lower density than water. While on Earth, it floats on water with its volume f1V (f1 < 1) submerged. On the other hand, on a spaceship accelerating with acceleration a < g (g is the acceleration due to gravity on Earth) in outer space, its submerged volume in water is f2V. Then:
A railway wagon (open at the top) of mass M1 is moving with speed v1 along a straight track. As a result of rain, after some time it gets partially filled with water so that the mass of the wagon becomes M2 and speed becomes v2. Taking the rain to be falling vertically and the water stationery inside the wagon, the relation between the two speeds v1 and v2 is :

1. Distance between the longitudes becomes zero on North Pole and South Pole.
2. Distance between the longitudes is maximum on the Equator.
3. Number of longitudes is more than number of latitudes.
Which of the statements given above is/are correct?
One block of 2⋅0 kg mass is placed on top of another block of 3⋅0 kg mass. The coefficient of static friction between the two blocks is 0⋅2. The bottom block is pulled with a horizontal force F such that both the blocks move together without slipping. Taking acceleration due to gravity as 10 m/s2, the maximum value of the frictional force is :
