Cube Notation is letters and letter character combinations to describe specific turns on a 2x2 cube, also called a pocket cube. The purpose of notation is to easily describe an algorithm or a scramble.
Uppercase letters describe one 90 degree clockwise turn of one layer the letter represents. If the letter is followed by an apostrophe then the turn is anti-clockwise.
