Study Notes
Introduction to Web Development
- The internet connects computers and devices around the world.
- A local area network (LAN) connects devices within a limited area, usually within a building.
- A wide area network (WAN) connects computers and devices over a large geographical area.
- LANs and WANs are part of the internet.
- The internet allows for communication, education, and entertainment.
- The World Wide Web (WWW) uses the internet for sharing and collecting data.
- Tim Berners-Lee invented the WWW while working at CERN in 1989.
- The WWW is a collection of information and services that travel over the internet.
- Think of the internet as roads, and the WWW as the cars and people that move around.
- Web 1.0 was static.
- Web 2.0 was dynamic.
- Web 3.0 is the Semantic Web, focused on meaning.
Internet Services
-
Communication Services allow individuals or groups to exchange information.
- Examples include email, instant messaging (chats), and video conferencing (zoom and gmeet).
-
Information Retrieval Services make it easier to access information available on the internet.
- Examples include databases like Google Scholar and Google Drive.
-
Web Services make accessing the Internet easier using applications.
- Examples include cloud computing services like Google Docs, Canva, and YouTube.
-
World Wide Web Services allow users to access web pages on the internet.
- Web pages can contain multimedia.
- Hyperlinks are clickable objects that allow users to navigate between web pages.
- The World Wide Web uses a client-server architecture, with web browsers acting as clients requesting data from servers via protocols like HTTP.
- HTTP uses a request-response system.
- An HTTP request contains information like the URL of the requested data.
- An HTTP response is sent back to the client with the requested data.
Introduction to the Internet
- The internet is a network of computers and other devices connected to each other.
- A local area network (LAN) is a network of computers and devices connected within a small geographical area.
- A wide area network (WAN) connects devices over a larger geographic area, such as a country or the world.
World Wide Web (WWW)
- The World Wide Web was invented by Tim Berners-Lee while working at CERN in 1989.
- The WWW is a collection of information and services that travel over the Internet.
- The Internet is analogous to roads, while the World Wide Web is the people and cars that move around on those roads.
- The WWW can be divided into three generations: Web 1.0 (static), Web 2.0 (dynamic), and Web 3.0 (semantic web, meaning).
Internet Services
- Internet services are categorized as Communication Services, Information Retrieval Services, Web Services, and World Wide Web Services.
- Communication Services facilitate the exchange of information between individuals or groups. Examples include email, groups or forums, instant messaging, and video conferencing.
- Information Retrieval Services provide access to information present on the internet. Examples include web search engines (e.g., Google), databases (e.g., Google Scholar), and online journal databases.
- Web Services refer to applications that facilitate access to the internet. Examples include cloud computing services (e.g., Google Docs, Canva), and YouTube.
- World Wide Web Services allow users to access web pages over the internet. These pages may contain multimedia elements, including text, images, audio, and video. These web pages are linked to each other through hyperlinks, providing a seamless user experience.
World Wide Web Structure
- The WWW structure utilizes a "request-response" system.
- The Hypertext Transfer Protocol (HTTP) is the standard used for communication between the client (browser) and the server on the internet.
- To access information on the internet, a client (web browser) requests data from a server via HTTP. This request includes the Uniform Resource Locator (URL) of the desired information.
- The server then responds to the client with the requested data, completing the "request-response" cycle.
