Information systems like databases are used to store and present information, making it easier to visually interpret and understand, faster to search, update and check for errors.
Web-based information systems make use of the world wide web (www). Most companies need a website today in order to keep up with the demand for up-to-date information. They use them to communicate with their customers, display advertisements and special offers, and make sales. Some examples of common websites are:
https://www.facebook.com/
https://www.youtube.com/
http://www.bbc.co.uk/news/scotland
A website is made up of files stored in a folder on a web server. Websites are accessed via browser software. Websites contain webpages and webpages are made up of:
HTML files for the content of the webpages
JavaScript files to allow for interactivity between the user and webpages
CSS files to create styles for each webpage
Multimedia files that are shown as part of webpages
Different pages have their own address and these addresses are used to let people access webpages from browser software.
The proper name for a website's address is its URL, which means Uniform Resource Locator. This tells your web browser the address of the web server which stores the pages you wish to display.
