Internet Fundamentals refer to the basic concepts and technologies that enable the functioning of the internet. This includes understanding how data is transmitted using protocols like TCP/IP, the structure of web addresses (URLs), domain names, and the role of servers and clients. It also covers the significance of browsers, search engines, and the World Wide Web, as well as basic security measures and the importance of connectivity through networks.

What is the internet and how does data travel across it?
The internet is a global network of connected computers. Data moves as small packets routed from sender to receiver using protocols like TCP/IP; routers determine the best path to deliver each packet.
What is TCP/IP and why is it important?
TCP/IP is the core set of protocols for the internet. TCP ensures reliable delivery of data by managing packets, while IP handles addressing and routing from source to destination.
What is a URL and what are its main parts?
A URL (Uniform Resource Locator) tells you how to access a resource: protocol (e.g., http/https), domain name, and optional path, query, and fragment.
What is DNS and what does a domain name do?
DNS (Domain Name System) translates human-friendly domain names into IP addresses so devices can locate servers on the internet.
What is a client and a server?
A client requests resources (such as a web page), and a server provides them in response, typically over HTTP/HTTPS.
