WHAT IS A WEB?
A website or web site is a collection of related network web resources, such as web pages, multimedia content, which are typically identified with a common domain name, and published on at least one web server.

HOW WEB PAGES WORK
-The server receives the request for a page sent by your browser.
– The browser connects to the server through an IP address; The IP address is obtained by translating the domain name.
– In return, the server returns the requested page.

STATIC AND DINAMIC WEBSITE
There are two main types of website, static and dynamic:
A static site is one that is usually written in plain HTML and what is in the code of the page is what is displayed to the user. A dynamic site is one that is written using a server-side scripting language such as PHP, ASP, JSP, or Coldfusion.

ACCESSIBILITY LEVELS

Level A – The most basic web accessibility features.
Level AA – Deals with the biggest and most common barriers for disabled users.
Level AAA – The highest (and most complex) level of web accessibility.
