The Global Descriptor Table (GDT) is a data structure used by Intel x86-family processors starting with the 80286 in order to define the characteristics of the various memory areas used during program execution, including the base address, the size, and access privileges like executability and writability. These memory areas are called segments in Intel terminology.
The GDT can hold things other than segment descriptors as well. Every 8-byte entry in the GDT is a descriptor, but these descriptors can be references not only to memory segments but also to Task State Segment (TSS), Local Descriptor Table (LDT), or Call Gate structures in memory. The last ones, Call Gates, are particularly important for transferring control between x86 privilege levels although this mechanism is not used on most modern operating systems... |
