HI, Before we look at the code used to build websites it is important to consider the different ways in which people access the web and clarify some terminology.
1 -BROWSERS
People access websites using software called a web browser, Popular examples include
Firefox, Microsoft Internet Explorer, Safari, Google Chrome, and Opera browsers etc. In order to view a web page users might type a web address into their browser, follow a link from another site, or use a bookmark.
"Software manufacturers regularly release new versions of browsers with new features and supporting new additions to languages. It is important, however to remember that many computer owners will not be running the latest versions of these browsers. Therefore you cannot rely on all visitors to your site being able to use the latest functionality offered in all browsers".
2 -WEB SERVERS
When you ask your browser for a web page, the request is sent across the Internet to a special computer known as a SERVER which hosts the Whole website, Web servers are special computers that are constantly connected to the Internet and are optimized to send web pages out to people who request them. Some companies run their own web servers, but it is more common to use the services of a web hosting company who charge a fee to host your site.
3 -DEVICES
People are accessing websites on an increasing range of devices including desktop computers, laptops, tablets, and Smart phones etc, It is important to remember that various devices have different screen sizes and some have faster connections to the web than others.
4 -SCREEN READERS
Screen readers are programs that read out the contents of a computer screen to a user. They are Mostly used by people with visual impairments, In the same way that many countries have legislation that require public buildings to be accessible to those with disabilities, many laws have also been passed that require websites be accessible to those with disabilities. It is interesting to note that technologies similar to those employed by screen readers are also being used in other areas where people are unable to read a screen, e.g when they are driving, jogging etc.
