Study Notes
Client/Server Model and the WWW
- The Client/Server model enables access to resources on the World Wide Web (WWW) using email and web browsers like Chrome, Safari, and Firefox.
- Web browsers act as client software, allowing users to interact with web resources hosted on web servers.
- Web servers respond to requests from clients using the HyperText Transfer Protocol (HTTP).
The HTTP Protocol
- HTTP serves as the fundamental application protocol for data communication on the WWW.
- Hypertext documents leverage hyperlinks for easy navigation, accessible by clicking or tapping in web browsers.
- A web address or Uniform Resource Locator (URL) identifies the location of a resource on a server.
Accessing the WWW
- Connecting to the Internet typically involves using a recognized WiFi network, making the device a host.
- To access a resource, entering a URL into the browser launches an HTTP request to the corresponding server.
HTTP Request Process
- Upon pressing ENTER after typing a URL, an HTTP request is sent to the server hosting the resource.
- Although web pages appear quickly, various processes occur within milliseconds, often around 40 ms for page load speed.
Behind the Scenes of Web Access
- The URL is transmitted to locate the server hosting the requested resource.
- The server retrieves the information via JavaScript or code.
- The server’s database processes and converts the code into HTML before sending it back to the client for display in the browser.
- Hypertext Markup Language (HTML) is the standard format for content meant for web browsers.
