PLL stands for "permutation of the last layer". In this step, the edges and corners become properly permutated after being properly orientated in OLL. Though it may sound very similar in description to OLL, it can be thought of as building on OLL rather than something entirely different. For example, when most people try to solve the Rubik's cube for the first time, they solve one side randomly, but they need to get the colors to align with the other centers to make it actually solved, just like here.

How is PLL solved?
PLL is solved through a series of algorithms like OLL, but with much fewer cases and algorithms, 21 algorithms for PLL compared to the 51 for OLL. But like OLL, PLL can be solved in 2 algorithms called "2-look PLL" instead of memorizing all 21 cases, this reduces the number of PLl cases to 6. A pdf of all 21 algorithms can be found here, and a link to a website with the 6 2-look PLL cases can be found here.
How are PLL cases organized?
Beyond just belonging to PLL cases, there are little subsets inside of PLL. These subsets are: adjacent corner swap, diagonal corner swap, and edge swap. The permutations are listed below.
Adjacent corner swap
All A-perms
F-perm
All G-perms
All J-perms
All R-perms
All T-perms
Diagonal corner swap
E-perm
All N-perms
V-perm
Y-perm
Edge swap
All U-perms
Z-perm
H-perm
