Line 17:
The x86 line of computers have 6 segment registers (CS, DS, ES, FS, GS, SS). They are totally independent of one another.

*FS/GS = General Purpose Segments▼

DS,ES,FS,GS,SS are used to form addresses when you want to read/write to memory. They don't always have to be explicitly encoded, because some processor operations assume that certain segment registers will be used.
