The task state segment (TSS) is a structure on x86-based computers which holds information about a task. It is used by the operating system kernel for task management. Specifically, the following information is stored in the TSS: Processor register stateI/O port permissionsInner-level stack … See more The TSS may reside anywhere in memory.
