I appreciated the review. Does anyone know of any credible and authoritative sources for defining internet technology terminology?
Thanks for the lesson!
As a review, I want to attempt to answer the questions that were asked during the beginning of the session:
How is data sent from one computer to another?
Data is sent over the internet using the TCP/IP protocol, which provides the standards for data transfer.
What is the relationship between a browser and a server?
A browser acts like a client and sends requests to the server, and the server waits for incoming requests and then sends back the data.
How is code turned into the experience that users see in their browsers?
When a user requests a webpage, the browser sends a request to the server. In response, the server sends back an HTML file that contains the contents of the page and any links to any additional resources needed to fully display the page resources like CSS stylesheets, media files, and JavaScript files. The browser then sends additional requests in parallel to get each of these resources, rendering and displaying them as soon as they are fully downloaded.
How has the web and web development changed from its invention to today?
Initially, the web was static and content was generated by a single source. It then evolved to become dynamic and interactive and enable user-generated content. Technical advances enabled these changes, like jQuery and the rise of web frameworks.
Then, with the rise of smartphones, websites must adapt to different devices and screen sizes. So, responsive design helped the websites to adjust based on different screens.
