Detailed Solution for Basics Of Internet MCQ Test - 1 - Question 3
Web search engines work with the help of two programs: 1. Spider: - Also known as a web crawler or bot, a spider is a program that systematically navigates the web, visiting web pages and collecting data. - It starts by visiting a specific web page and then follows the links on that page to discover and visit other pages. - The spider collects information about each page it visits, such as the page title, URL, metadata, and the content of the page. - It stores this information in a database or index for later retrieval. 2. Indexer: - The indexer is another program that works in conjunction with the spider. - Its main task is to analyze and organize the information collected by the spider. - It processes the collected data and creates an index, which is a structured database that enables efficient searching and retrieval of information. - The indexer extracts keywords and other relevant information from the web pages and associates them with the respective URLs. - It also assigns weights or rankings to the indexed pages based on various factors like relevance, popularity, and quality. Together, the spider and indexer form the backbone of a web search engine: - The spider crawls the web, discovering and collecting information from web pages. - The indexer processes and organizes this information, creating an index that enables fast and accurate searching. - When a user enters a search query, the search engine utilizes the index to quickly retrieve relevant results and present them to the user. In conclusion: - Web search engines rely on the spider to discover and collect information from web pages, and the indexer to process and organize this information into an index. - These two programs work together to enable efficient searching and retrieval of web content.

______________ protocol defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands.
Detailed Solution for Basics Of Internet MCQ Test - 1 - Question 8
The HTTP Protocol The HTTP protocol, which stands for HyperText Transfer Protocol, is a protocol that defines how messages are formatted and transmitted over the internet. It specifies the actions that web servers and browsers should take in response to various commands. Here's a detailed explanation of the HTTP protocol: 1. Message Formatting: - HTTP messages consist of a request or a response. - The request message is sent by a client (such as a web browser) to a server, requesting a specific action to be performed. - The response message is sent by the server to the client, providing the requested information or indicating an error. 2. Message Transmission: - HTTP messages are transmitted over TCP/IP, which is the underlying protocol for internet communication. - TCP/IP ensures that the messages are divided into packets and delivered reliably to the intended recipient. 3. Actions for Web Servers: - Web servers receive HTTP requests from clients and process them. - They perform actions such as retrieving resources (HTML files, images, etc.) from the server's file system or executing server-side scripts. - The server then constructs an HTTP response message and sends it back to the client. 4. Actions for Web Browsers: - Web browsers initiate HTTP requests to web servers to retrieve web pages. - They send a request message specifying the desired resource (e.g., a URL). - The browser then receives the response message from the server and renders the web page for the user to view. 5. Commands and Responses: - HTTP defines a set of commands (methods) that clients can use in their requests, such as GET, POST, PUT, and DELETE. - The server responds to these commands with specific status codes, indicating the success or failure of the request (e.g., 200 for success, 404 for not found). Conclusion: The HTTP protocol is essential for communication between web servers and web browsers. It defines the format and transmission of messages, as well as the actions to be taken by servers and browsers. It enables the retrieval and rendering of web pages, making it a fundamental protocol for the World Wide Web.

Types of URLs: There are two types of URLs: absolute and relative. Absolute URLs: Absolute URLs provide the complete address of a webpage, including the protocol (http:// or https://), domain name, and file path. They are used to link to webpages outside of the current website. Examples of absolute URLs include: - http://www.example.com/index.html - https://www.google.com/search?q=example Relative URLs: Relative URLs provide a partial address of a webpage, which is relative to the current webpage's location. They are used to link to webpages within the same website. Examples of relative URLs include: - index.html (links to a webpage in the same directory) - ../about.html (links to a webpage in the parent directory) - /contact.html (links to a webpage in the root directory) Difference between Absolute and Relative URLs: - Absolute URLs include the full address, while relative URLs only include a partial address. - Absolute URLs can be used to link to any webpage on the internet, while relative URLs are limited to the current website. - Absolute URLs are typically longer and contain more information, while relative URLs are shorter and more concise. Conclusion: In summary, URLs can be classified into two types: absolute and relative. Absolute URLs provide the complete address of a webpage, while relative URLs provide a partial address relative to the current webpage's location. Understanding the difference between these two types of URLs is essential for effectively linking webpages within a website.
