Study Notes

The Origin of the Internet

The internet is a network of networks.
It was created to enable secure communication.
It was established with the creation of the Advanced Research Projects Agency Network (ARPANET).

How the Internet Works

The internet functions as a client/server network.
Clients request data from servers, which then return data to the clients.
The internet backbone is the primary network that connects other networks.
Each computer on the internet has a unique Internet Protocol (IP) address.
IP addresses are used to identify computers and websites.

URLs, Protocols, and Domain Names

Every website has a unique address, known as a URL.
URLs are comprised of different components to identify web documents.
Protocols, such as Hypertext Transfer Protocol (HTTP) and File Transfer Protocol (FTP), define how data is transferred between computers.
Domain names are more user-friendly representations of IP addresses.
The ‘top-level domain’, such as .com, .org, or .net, indicates the website's category, purpose, or geographic location.
