[Audio] The internet is a global network of interconnected computers and servers that communicate with each other using standardized protocols. The web, on the other hand, refers specifically to the collection of interlinked hypertext documents that can be accessed via the internet. In essence, the internet provides the infrastructure for the web to exist, while the web is a service built upon that infrastructure. To illustrate this distinction, consider that the internet allows for communication between devices, whereas the web enables users to access and share information through hyperlinks. While the terms are often used interchangeably, they have distinct meanings. Understanding this difference is crucial for effective communication and collaboration in today's digital landscape..

[Audio] The web is an information-sharing model that involves coordinating internet servers to support specially formatted documents. These documents use the HTML standard and rely on the HTTP protocol for communication. They also include links to other documents such as graphics, audio, and video files. The web itself is a network of information resources that can be accessed through a uniform naming scheme, protocols, and hypertext. This allows users to navigate easily among different resources..

[Audio] The history of the web began in 1989 when two researchers at CERN, Tim Berners-Lee and Robert Cailliau, developed the concept of the World Wide Web. This idea was further developed into a project in 1990, which aimed to create a system that could share information across the internet. Over time, this project evolved into the web we use today, with key milestones including the creation of the W3C consortium in 1994, which focused on establishing standards for web technologies. The web has become an essential tool for global communication and access to information, revolutionizing the way people interact and share knowledge..

[Audio] The character of a person can be described as being very good at what they do, but this does not necessarily mean that they are good people. A person may have exceptional skills, but still possess negative traits such as dishonesty, arrogance, and lack of empathy. Conversely, someone who lacks exceptional skills may still be a good person with positive qualities such as kindness, humility, and compassion. The key to success is not solely dependent on one's abilities, but also on their moral character..

[Audio] ## Step 1: Identify the main components of a URI A Uniform Resource Identifier (URI) is composed of two main components: the Uniform Resource Locator (URL) and the Uniform Resource Name (URN). ## Step 2: Explain the function of the URL The Uniform Resource Locator (URL) is the part of the URI that users access to reach the desired resource. ## Step 3: Describe the role of the URN The Uniform Resource Name (URN) is another term for the URI, but it refers specifically to the name of the resource itself. ## Step 4: Clarify the purpose of the URI Together, the URL and URN provide a complete and accurate description of the resource's location and identity. ## Step 5: Summarize the significance of the URI In essence, the URI serves as a unique identifier for resources on the internet, allowing users to easily find and access them. The final answer is:.

[Audio] The Uniform Resource Name (URN) is a type of identifier used to uniquely identify a resource on the internet. It is similar to a URL but has some key differences. One of the main differences is that URNs are case-insensitive whereas URLs are not. This means that a given URN can have multiple equivalent forms, such as http://example.com and urn:isbn:0123456789, while a URL would only have one form. Another key difference is that URNs do not rely on a specific protocol like HTTP, whereas URLs always use HTTP. URNs are often used for identifying non-web resources, such as documents, images, and other types of digital content. They are also more compact than URLs, making them easier to store and transmit. Overall, URNs provide a more flexible and efficient way of identifying and accessing resources on the internet..

[Audio] The web is a complex system that involves multiple components working together to provide access to information. At its core, it's built around the concept of hyperlinks, which allow users to navigate from one webpage to another. This allows for easy sharing and dissemination of information across the globe. The web also utilizes various protocols such as HTTP to facilitate communication between devices and servers. Additionally, the use of server-side scripts like PHP or ASP.NET enables developers to create dynamic content and interact with databases. Furthermore, the web browser plays a crucial role in rendering content and facilitating user interaction. Overall, the web's architecture is designed to enable seamless communication and information exchange between devices and servers..

[Audio] The web has been around for decades, but its evolution continues unabated. The Internet Corporation for Assigned Names and Numbers (ICANN) plays a significant role in managing the global network infrastructure. ICANN is responsible for coordinating the registration process for domain names, ensuring that each domain name corresponds to a unique IP address. This process is critical because it enables users to access specific websites and services using their preferred domain names. Furthermore, ICANN oversees the allocation of IP addresses, which is necessary for the functioning of the internet. Without ICANN, the internet would be unable to function efficiently, as there would be no standardized system for assigning IP addresses. The organization's efforts to maintain order and stability in the global network infrastructure are invaluable..
