Detailed Description

The Task State Segment (TSS) is a special data structure for x86 processors which holds information about a task. The TSS is primarily suited for hardware multitasking, where each individual process has its own TSS. In Software multitasking, one or two TSS's are also generally used, as they allow for entering Ring 0 code after an interrupt. (OSDev Wiki)
