Web Servers and Protocols [4:28]
The discussion kicks off with web servers and protocols. It explains important terms like "transmission control protocol". The video touches upon how a browser initiates a secure SSL session to communicate with a server. It also mentions components that act as a bridge between merchant and bank servers.
Server Technologies [13:05]
This section talks about server technologies, explaining that a web server is basically a computer that hosts websites. It's used for storing, processing, and serving large amounts of data.

Static vs. Dynamic Pages [20:25]
The video differentiates between static and dynamic web pages. Static pages are like fixed documents, while dynamic pages can change based on user input or other factors.
Client-Side Scripting [24:52]
This part talks about client-side scripting, where program codes are written inside HTML pages. Examples include JavaScript, VBScript, JSP, and PHP. The main use is for validating data at the client side.
Server-Side Scripting [28:48]
Server-side scripting is discussed next, explaining that these scripts are executed on the web server. They're mainly used for connecting to databases and returning data to the web server.
Cascading Style Sheets (CSS) [30:34]
