: 

GDT = Global Descriptor Table - like a look-up table to translate 
between a selector and a "real" address.

TSS = Task State Segment??? - hold info about a specific task
(eg, an app under windows), hold info like registers, stack pointers etc etc.

Hope that helps. If I'm wrong, please correct me (I'm sure you all will).
