What the heck, is an app?

How many times have you heard the word app and in how many different contexts? So, what exactly is an app? An app is computer shorthand for a software application. Now, software applications come in all shapes and sizes. There are apps for websites, apps for computers, apps for smart phones, apps for tablets, and even apps within apps!
