Building Your Own Website from the Ground Up

What is a Website?

A website consists of one or more "pages" that may be accessed by a web browser.
A web browser is a piece of software that runs on your local computer but shows content from a website hosted on a web server.
A web server is a computer located at a particular address on the internet that is configured to respond to requests from web browsers and provide "pages" of content.
An "IP address" is an "Internet Protocol address," a unique number that identifies a computer on a network; the whole internet is nothing but a set of uniquely identified computers that can send packets of information to each other by means of their IP addresses.
A page is a handy metaphor for "everything we see on our computer screen in response to a request we made of a server through our browser." The metaphor must not be pressed too closely; the content displayed in a browser by a server can be much more subtle and dynamic than a piece of paper or a page in a book.

A Domain Name is a human-readable alias for an IP address that is used in a URL.

A URL is a "Universal Resource Locator" (or "Uniform Resource Locator") that allows a browser to connect to a particular part ("page") of a website.
