In typography the all lowercase text lacks capital letters. This unicase style is often used for poetic/artistic effect but it's often seen in computer languages. It's a common thing to type all lowercase in informal communications such as SMS or internet chat, especially if a single sentence is transmitted.
All capital letters usually mean shouting in chat conversations so make sure to use them carefully. Titles of book covers are often written in all uppercase but they can be seen on legal documents, advertisments, newspaper headlines and everywhere they need the text to stand out more.
