Website is a generic term....like Car or Table.
We all know what they are but there are so many different types or models or styles.
A table is a flat working surface built to a certain height by relevant supports in certain materials.
A car is a motorised vehicle with usually four wheels and an engine and an interior.
Likewise a website is just a set of boxes arranged in a particular manner containing different media.
What you put into those boxes will depend on what you decide your message is and how you want to communicate it.
