 Explain hypermedia www and internet

Here's an explanation of **hypermedia**, **World Wide Web (WWW)**, and the **Internet**:

### 1. **Hypermedia**

Hypermedia is an extension of hypertext, where **multimedia** elements such as text, images, videos, and audio are linked together in a non-linear way using hyperlinks. The user can interact with different types of content by clicking on these links, navigating from one piece of information to another.

- **Hypertext**: Documents with interconnected text (e.g., a webpage where words or phrases are linked).
 

**Hypermedia**: Expands hypertext by integrating **multimedia elements** like videos, images, and animations. For example, clicking on an image that leads you to a video or audio file is a form of hypermedia.

Hypermedia structures provide a rich and interactive way of accessing information, allowing users to navigate based on their preferences or needs.


### 2. **World Wide Web (WWW)**

The **World Wide Web (WWW)**, often just called "the Web," is a system of interlinked hypertext documents and other resources, accessible via the Internet. It was created by Tim Berners-Lee in 1989 to facilitate sharing and access to information globally.

**Web Pages**: Documents that can contain text, images, audio, video, and other multimedia, often written in **HTML** (Hypertext Markup Language).

 

**Hyperlinks**: Allow users to navigate between these pages. Clicking on a link can take you to another document, image, or even another website.
 

**Web Browser**: To access the web, you use a web browser (e.g., Google Chrome, Firefox). This software retrieves and displays content from the web.

While the **WWW** is a massive component of the Internet, it's important to note that it is **not the same thing as the Internet**.


### 3. **Internet**
The **Internet** is a global network of interconnected computers and servers. It allows computers, devices, and networks to communicate with each other. The Internet is much larger than just the Web.
 

**Protocols**: It uses a suite of protocols (primarily **TCP/IP**) to exchange data. The Web uses one of these protocols, **HTTP (Hypertext Transfer Protocol)**, to transmit data like web pages.

 

**Email, File Sharing, Streaming, and More**: Besides the WWW, the Internet supports other services such as email (using protocols like **SMTP**, **IMAP**), file sharing, cloud services, online gaming, and more.


### Relationship Between Hypermedia, WWW, and the Internet:
 

**Hypermedia** refers to the interactive content experience (such as linked videos, texts, and images).
 

The **World Wide Web** is the collection of these hypermedia documents and resources, interconnected by hyperlinks.
 

The **Internet** is the infrastructure or network that connects all devices and servers globally, enabling services like the WWW and email to function.

Unit 2: Foundations of Ownership, Security Related Concepts in Blockchain

  Unit 2: Foundations of Ownership, Security Related Concepts in Blockchain Foundations of Ownership In traditional systems, ownership is often documented and verified by centralized authorities (e.g., land registries, banks). In blockchain, ownership is established and proven through cryptographic methods, primarily using public-key cryptography . Public and Private Keys: Each user on a blockchain network has a unique pair of cryptographic keys: a public key and a private key. The public key acts as an address, similar to an account number, visible to everyone. It's used to receive assets or data. The private key is a secret code that grants control over the assets associated with the public key. Only the person possessing the private key can authorize transactions from that address. Digital Signatures: To prove ownership or authorize a transaction, a user digitally "signs" a message or transa...

Unit-1 Foundations of Software Systems and Blockchain

  Unit 1: Foundations of Software Systems and Blockchain 1. Layers of a Software System Software systems are typically organized into layers to separate responsibilities, improve maintainability, and allow independent scaling. Common layers include: Presentation Layer: Handles user interface (UI) and user interaction (e.g., web pages, mobile app screens). Application/Business Logic Layer: Contains the core business rules and orchestrates data flow, processing user requests (the "brains" of the application). Data Access Layer (DAL): Provides an interface for the application to interact with data storage, abstracting database complexities. Data Layer: The actual persistent storage for data (e.g., databases, file systems). This layered approach promotes modularity and makes systems easier to develop, test, and update. 2. Integrity Integrity in software systems ensures that data is accurate, consistent, and trustworth...
