Internet and Web Browsing

Internet and Web Browsing

Overview

Internet and Web Browsing is a fundamental topic in the Computer Knowledge section of HSSC CET. Questions from this area test your understanding of how the internet works, browser functionality, search engine operations, and basic file transfer concepts. This topic carries moderate weightage and is relatively scoring because the concepts are practical and based on everyday computer usage.

For HSSC CET, you need to master three core areas: browser features and settings, effective search engine usage, and the mechanics of downloading/uploading files. Most questions are straightforward if you understand the terminology and basic operations. Since Haryana government offices increasingly rely on digital services, practical internet knowledge is essential for the roles you will be recruited into.

Key Concepts

• Internet vs World Wide Web (WWW): Internet is the global network of connected computers; WWW is a service that runs on the internet using HTTP protocol to access web pages. The internet existed before the web.
• Web Browser: Software application used to access and display web pages. It interprets HTML, CSS, and JavaScript code to render websites visually. Examples include Google Chrome, Mozilla Firefox, Microsoft Edge, and Safari.
• URL (Uniform Resource Locator): The complete web address used to access a resource. Structure: protocol://domain-name/path. Example: https://www.haryana.gov.in/departments
• Search Engine: A software system that searches a database of internet sites based on keywords. It uses crawlers (bots) to index web pages and algorithms to rank results.
• HTTP vs HTTPS: HTTP (Hypertext Transfer Protocol) transfers data without encryption. HTTPS adds SSL/TLS encryption for secure communication—look for the padlock icon in the address bar.
• Download vs Upload: Downloading means transferring files FROM the internet TO your computer. Uploading means transferring files FROM your computer TO the internet.
• Cache and Cookies: Cache stores temporary copies of web pages for faster loading. Cookies store user preferences and login information on your device.
• ISP (Internet Service Provider): Company that provides internet connectivity to users. Examples in India: BSNL, Jio, Airtel, ACT Fibernet.

Key Facts

Common Search Engine Operators:

• Use quotation marks ("exact phrase") for exact match searches
• Use minus sign (-word) to exclude terms
• Use site:domain.com to search within a specific website
• Use filetype:pdf to find specific file formats

Worked Examples

Example 1: Identifying URL Components

Question: In the URL https://www.haryana.gov.in/education/schools.html, identify the protocol, domain name, and file name.

Solution:

• Step 1: Protocol is the part before :// → https
• Step 2: Domain name is between :// and the first / → www.haryana.gov.in
• Step 3: Path includes folders and file → education/schools.html
• Step 4: File name is the last part → schools.html

Example 2: Browser Feature Identification

Question: Ramesh wants to save a webpage address so he can quickly visit it later without typing the full URL. Which browser feature should he use?

Solution:

• Step 1: The requirement is to save a webpage for quick future access
• Step 2: This is NOT downloading (that saves the actual page content)
• Step 3: This is the Bookmark (or Favourite) feature
• Step 4: Access via Ctrl+D shortcut or star icon in address bar

Example 3: Download vs Upload Scenario

Question: Priya fills an online job application form and attaches her resume from her computer. Later, she saves the admit card from the website to her computer. Identify which action is upload and which is download.

Solution:

• Attaching resume: File moves FROM computer TO website → Upload
• Saving admit card: File moves FROM website TO computer → Download

Common Mistakes

• Confusing Internet with WWW: Students write "WWW was invented in 1969" → Wrong. The internet (ARPANET) started in 1969; WWW was invented by Tim Berners-Lee in 1989.
• Mixing up HTTP and HTML: HTTP is a protocol for transferring data; HTML is a markup language for creating web pages. They serve completely different purposes.
• Thinking browsers and search engines are the same: Chrome is a browser (software to view pages); Google is a search engine (service to find pages). You can use Firefox browser to access Google search engine.
• Confusing cache with cookies: Cache stores page content (images, scripts) for faster loading. Cookies store user data (login status, preferences). Clearing cache affects speed; clearing cookies logs you out.
• Assuming all downloads are unsafe: Students think downloading always involves viruses → Only downloads from untrusted sources are risky. Official government websites and reputed platforms are generally safe.
• Forgetting HTTPS importance: Treating HTTP and HTTPS as identical → HTTPS is essential for secure transactions. Never enter passwords or banking details on HTTP sites.

Quick Reference

• Internet = Network; WWW = Service on that network using HTTP
• URL Format: Protocol://Domain/Path/Filename
• Download = From Web to PC; Upload = From PC to Web
• HTTPS = Secure (has padlock); HTTP = Not encrypted
• Ctrl+D = Add Bookmark; Ctrl+H = View History; Ctrl+Shift+N = Incognito Mode
• Cache = Stored page data; Cookies = Stored user preferences
• Search tip: Use quotes for exact phrases, minus sign to exclude words
