What is HTML and HTML is used for

HTML (HyperText Markup Language) is used to structure the content of web pages and define how content, like text, images, and other media, is displayed in a web browser. It provides the fundamental structure for creating website. 

Detailed breakdown

Structuring web content: HTML uses tags to define elements like headings, paragraphs, lists, images, and links, creating a hierarchical structure for the content. 

Interpreting content for browsers: Web browsers interpret the HTML code to render the content in a visually understandable format for users. 

Foundation for websites: HTML is the core language for creating web pages, and along with CSS and JavaScript, forms the basis of modern web development. 

Not a programming language: While it's a markup language, not a programming language, it's a great starting point for learning web development. 

Internet and it's uses

The internet is a global network of interconnected computer networks that allows users to access and share information and resources. It's essentially a "network of networks," connecting billions of devices worldwide. This interconnected computer enables communication, data sharing, and access to a vast range of online services. 

Here's some more details about internet.

Interconnected Network: The Internet is not a single, monolithic network, but rather a vast collection of individual networks, both public and private, that are linked together.

Communication and Data Exchange: It facilitates the exchange of information between devices through standardized communication protocols, like TCP/IP.

Access to Services: The Internet provides access to a wide range of services, including websites, email, social media, online applications, and cloud storage. 

Global Reach: It connects devices and users across geographical boundaries, enabling communication and collaboration on a global scale. 

Foundation for Modern Life: The Internet has become an essential tool for education, business, entertainment, and personal communication. 

In essence, the Internet is the infrastructure that allows us to connect, communicate, and access information from anywhere in the world. 

Introduction of Computer and Key Components

A computer is an electronic device that can perform a variety of tasks by processing data. It receives input, stores and processes data, and then provides output. Basic computer knowledge includes understanding hardware components like the CPU, memory, and storage, as well as software, including the operating system and applications.

Key Components and Concepts:

Hardware:

The physical parts of the computer, including the CPU, memory (RAM), storage devices (hard drive, SSD), input/output devices (keyboard, mouse, monitor), and other peripherals.

Software:

The set of instructions (programs) that tell the computer what to do. This includes the operating system (like Windows or macOS) and applications (like word processors, web browsers, games).

Input: Data or instructions entered into the computer, such as typing on a keyboard or clicking a mouse.

Processing: the computer's manipulation of data according to instruction, often involving the CPU and memory. 

Output: The results of processing displayed on the monitor or sent to other devices.

Storage: Saving data and programs on a storage device for later use.
