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.
