• A collection of connected computers is a network.
• Each personal computer connects to a server, which serves files for your favorite websites.
• Each personal computer is called a client. The relationship is client-server.
• Each server distributes info about each computer like the name (DNS) and location (IP).
• Servers also store data that clients can request, like MP3s or news articles.
• Clients view the internet through an application: web browser.
• Websites are documents that sit on a computer and which are requested by users that want to "visit" them.
• The websites YOU make are documents. You'll create them, save them and upload them to a server for others to view.

When creating our web applications, we write a bunch of documents, upload them to the server and clients can enter the address for the data to view and interact with it.
