I'm guessing that at sometime in the last few years you heard someone talking about code. You probably know someone who spends their day on the computer writing the code that makes our internet such a lovely place to website watch...window shop...peruse... 
There are all types of computer programming 'languages'.  Some, like HTML, CSS and JavaScript, you probably have heard of .  While others, such as PHP or Ruby, may be less familiar to you.

Even though sometimes technology advances faster than we can keep up, it's a good idea to at least be familiar with what tools are used to build the places where we spend a lot of our time. Similar to when you brush up on the native tongue when visiting another country, you should also learn the language of the sites, apps and interactive websites that are speaking to you
 right now.
