Differences btw speakers?

Can someone pls explain to me the difference btw speakers as listed here- monitor, full, or planar? I'm new to this whole this and looking for a system and would like to know what advantages/disadvantes/characteristics these different speakers have.

Monitor speakers are generally smaller "bookshelf" speakers.

Full is for FullRange and are normally floor standers

Planar speakers are like Martin Logans or Magnepans. It is a thin membrane between two charge stators that cause the membrane to move and cause sound, opposed to the cone setup of dynamic speakers
