Web Development
Websites that we use everyday to find information, online shopping, social media, etc. are part of the World-Wide Web. Websites are designed and created so that they work well and people can use them easily. A whole bunch of technologies work behind the scenes to get web pages to show up on your device.
Web servers run code to create and send out web pages using 'back-end' systems like Flask, with data from databases like SQLite. Data is sent to and from web servers using the HTTPS communication protocol.
The web browser on your device takes the HTML web pages , the CSS stylehssets and the JavaScript code sent to it from a web server, and renders the web page so that you can view and interact with it.
There is a lot going on!
