Segment descriptor

In memory addressing for Intel x86 computer architectures, segment descriptors are a part of the segmentation unit, used for translating a logical address to a linear address. Segment descriptors describe the memory segment referred to in the logical address.The segment descriptor (8 bytes long in 80286) contains the following fields: 1. * A segment base address 2. * The segment limit which specifies the segment size 3. * Access rights byte containing the protection mechanism information 4. * Control bits
