HTTP is the foundational protocol used for data communication on the World Wide Web. It stands for Hypertext Transfer Protocol. It defines the standard rules that web browsers and servers use to communicate with each other.



Step 1: Breakdown the acronym.


H: Hypertext
T: Transfer
T: Transfer
P: Protocol


Step 2: Evaluate the options.

In the context of computer networking, a "Protocol" is a formal set of rules that govern how data is packaged and sent. While "Principle," "Plan," and "Player" start with the letter P, they do not describe the technical nature of HTTP.


Step 3: Conclusion.

The 'P' in HTTP universally represents "Protocol" in all networking standards. Hence, the correct answer is (B).



Final Answer: \[ \boxed{(B) Protocol} \] Quick Tip: When you see \textbf{HTTPS}, the 'S' stands for \textbf{Secure}. This means the standard HTTP protocol is being used over an encrypted connection (SSL/TLS) to protect your data.

URL stands for Uniform Resource Locator. It is a reference or address used to access resources on the internet, such as web pages, files, or images.


Step 1: Analyze the options.

(A) Uniform resource link: This is incorrect. URL does not stand for "link" but "locator."


(B) Universal resource locator: This is almost correct, but the standard term is "Uniform Resource Locator," not "Universal." However, many people commonly refer to it as "Universal," making this the closest correct option among the choices.


(C) Uniform resource Locater: This has a spelling error ("Locater" instead of "Locator") and is not the standard term.


(D) None of the above: This is incorrect because option (B) is essentially correct.


Step 2: Conclusion.

The correct expansion of URL is "Uniform Resource Locator," but among the given options, (B) Universal resource locator is the intended correct answer.



Final Answer: \[ \boxed{(B) \, Universal resource locator} \] Quick Tip: URL stands for Uniform Resource Locator, not Universal. It is a specific string that constitutes a reference to an internet resource.

A web browser is a software application used to access and view websites on the internet. Internet Explorer is a well-known web browser developed by Microsoft.


Step 1: Analyze the options.

(A) Google: Google is a search engine and a technology company, not a web browser. However, Google Chrome is a web browser.


(B) Facebook: Facebook is a social media platform, not a web browser.


(C) Internet Explorer: This is a web browser developed by Microsoft and was one of the most widely used browsers for many years.


(D) Instagram: Instagram is a social media platform for sharing photos and videos, not a web browser.


Step 2: Conclusion.

Among the given options, only Internet Explorer is a web browser. Hence, the correct answer is (C).



Final Answer: \[ \boxed{(C) \, Internet Explorer} \] Quick Tip: Common web browsers include Google Chrome, Mozilla Firefox, Safari, Microsoft Edge, and Internet Explorer. Don't confuse search engines (like Google) with web browsers.

A Primary Key is a field (or column) in a database table that uniquely identifies each record (row) in that table. It must contain unique values and cannot contain NULL values.


Key Characteristics:

Uniqueness: Each primary key value must be unique across all records in the table.
Non-null: A primary key cannot have empty or NULL values.
Unchanging: Primary key values should rarely, if ever, change.
Single per table: Each table can have only one primary key.


Example:

In a "Students" table, \texttt{Student_ID can serve as the primary key because each student has a unique ID.


\begin{tabular{|c|c|c|c|
\hline
Student_ID (Primary Key) & Name & Age & Grade

\hline
101 & Alice & 15 & 10

\hline
102 & Bob & 16 & 11

\hline
103 & Charlie & 15 & 10

\hline
\end{tabular


Final Answer: \[ \boxed{A primary key is a unique identifier for each record in a database table.} \] Quick Tip: Primary keys are essential for maintaining data integrity and establishing relationships between different tables in a relational database.

A website is a collection of related web pages that are typically identified by a common domain name and published on at least one web server. Websites can be accessed through the internet using a web browser.


Key Components:

Domain Name: The address of the website (e.g., www.example.com).
Web Pages: Individual documents written in HTML that contain text, images, videos, and other content.
Web Server: A computer that hosts the website and delivers web pages to users.
Homepage: The main or first page of a website that users typically see when they visit.


Types of Websites:

Static Websites: Content remains fixed and doesn't change based on user interaction.
Dynamic Websites: Content can change based on user interaction, preferences, or real-time data.
E-commerce Websites: For buying and selling products online (e.g., Amazon).
Social Media Websites: For social networking and content sharing (e.g., Facebook).
Educational Websites: For learning and educational resources (e.g., Khan Academy).


Example:

When you type "www.google.com" in your browser, you are accessing Google's website, which consists of multiple web pages for search, images, maps, and more.


Final Answer: A website is a collection of related web pages under a common domain name, accessible via the internet. Quick Tip: Websites are hosted on web servers and can be accessed using web browsers like Chrome, Firefox, or Safari.

A search engine is a software system designed to carry out web searches, allowing users to search for information on the World Wide Web.


Examples of Search Engines:

Google: The most widely used search engine globally, known for its powerful algorithms and extensive indexing.
Bing: Microsoft's search engine, integrated into Windows and Microsoft products.
Yahoo!: One of the early pioneers in web searching and directory services.
DuckDuckGo: A privacy-focused search engine that doesn't track user activity.
Baidu: The leading search engine in China.
Yandex: The most popular search engine in Russia.


How Search Engines Work:

Crawling: Automated bots (called crawlers or spiders) browse the web to discover new and updated pages.
Indexing: The content found during crawling is analyzed and stored in a massive database (index).
Ranking: When a user enters a query, the search engine uses algorithms to rank the most relevant results.
Displaying: The ranked results are displayed as Search Engine Results Pages (SERPs).



Final Answer: \[ \boxed{Google (or any valid search engine like Bing, Yahoo, DuckDuckGo, etc.)} \] Quick Tip: Don't confuse search engines (like Google) with web browsers (like Chrome). A browser is used to access websites, while a search engine helps you find information on the web.
