In aligned system you place the dimensions( or numerals) above the dimension lines so that they can be read from bottom or right edge of your sheet.

In unidirectional system, all the numerals are placed along the dimension lines, all in the same direction such that they can be read from the bottom edge.

This figure explains it clearly: http://www.maelabs.ucsd.edu/mae_guides/cad/dimensioning/Dimensioning_Fundementals_files/image034.gif
