Olympiad Test: Internet And E-mail - 2 - Class 6 MCQ

Web Indexing and Crawling

In order to provide accurate and up-to-date search results, several Internet programs systematically browse the internet. This process, known as web indexing, involves analyzing and storing information from web pages. One of the main steps in web indexing is crawling, where these programs navigate through websites and gather data.

Explanation:

Web indexing is the process of collecting and organizing data from web pages to create searchable indexes. It allows search engines to quickly retrieve relevant information when a user performs a search query. Crawling is a crucial step in this process, where programs, often referred to as web crawlers or spiders, systematically browse the internet to discover and analyze web pages.

Here is a breakdown of the options provided:

• Option A: Filtering - Filtering refers to the process of selecting or excluding specific data based on predefined criteria. While filtering may be involved in web indexing, it is not the main process.


• Option B: Crawling - This is the correct answer. Crawling is the systematic browsing of websites by web crawlers to gather data for web indexing.


• Option C: Phishing - Phishing is a type of cyber attack where individuals are deceived into revealing sensitive information such as passwords or credit card details. It is not related to web indexing.


• Option D: None of these - This option is incorrect as the correct answer is option B (Crawling).

Therefore, the correct answer is option B: Crawling.

Identifying the Object: Plug-in

• It is a piece of software. A plug-in is a software component that can be added to another software application to enhance its functionality.


• It enhances another software application. Plug-ins are designed to add specific features or capabilities to existing software applications.


• It usually cannot be run independently. Plug-ins are dependent on the main software application and typically cannot be executed as standalone programs.


• It sometimes modifies the interface. Some plug-ins may alter the user interface of the software application they are integrated with, providing additional controls or options.


• It can also modify the behavior of web browsers. Plug-ins often extend the functionality of web browsers, allowing them to display certain types of content or execute specific tasks.

Therefore, based on the given characteristics, the object being described is a plug-in. It is a software component that enhances another application, cannot be run independently, may modify the interface, and can also modify the behavior of web browsers.

Identifying the Website:

The website in question can be identified based on the following characteristics:

Regular Article Posting:

• The website posts articles on a regular basis.

Reverse Chronological Order:

• The articles on the website are usually displayed in reverse chronological order, with the latest articles appearing first.

Conclusion:

Based on these characteristics, the website can be identified as a Blog.

A blog is a type of website or online platform where individuals or organizations regularly publish articles, posts, or entries. These articles are typically displayed in reverse chronological order, with the most recent posts appearing at the top. Blogs often cover a specific topic or niche, and they allow readers to engage with the content through comments and social media sharing.

Some examples of popular blogging platforms include WordPress, Blogger, and Medium. Blogs can be personal or professional, serving as a platform for individuals to share their thoughts, expertise, or experiences, or as a means for businesses to communicate with their audience and provide valuable content.

Please note that while a blog may have elements of a web forum, bulletin board, or news board, the key characteristics mentioned in the question (regular article posting and reverse chronological order) align most closely with the concept of a blog.

Odd One Out:
The odd one out is option D: TCP.
Explanation:
TCP stands for Transmission Control Protocol, which is a protocol used for establishing and maintaining network connections. The other options, Bridges, Routers, and Gateways, are all network devices or technologies, whereas TCP is a protocol.
Details:
Below are the details of each option:
- Bridges: Bridges are network devices that connect multiple local area networks (LANs) together. They operate at the data link layer of the OSI model and are used to extend network coverage and improve network performance.
- Routers: Routers are network devices that forward data packets between different networks. They operate at the network layer of the OSI model and use routing tables to determine the best path for data transmission.
- Gateways: Gateways are devices that enable communication between networks with different protocols or architectures. They can perform protocol translation, data format conversion, and other necessary tasks to allow different networks to communicate with each other.
- TCP: TCP is a protocol that provides reliable, ordered, and error-checked delivery of data packets over an IP network. It is used in conjunction with the Internet Protocol (IP) to establish connections between devices and ensure the reliable transmission of data.
In summary, Bridges, Routers, and Gateways are all network devices, while TCP is a protocol used for data transmission. Therefore, TCP is the odd one out in this context.
