The task state segment is a special 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 state
- I/O port permissions
- Inner-level stack pointers
- Previous TSS link
All this information should be stored at specific locations within the TSS as specified in the IA-32 manuals.

Famous quotes containing the words task and/or state:
“To write weekly, to write daily, to write shortly, to write for busy people catching trains in the morning or for tired people coming home in the evening, is a heartbreaking task for men who know good writing from bad. They do it, but instinctively draw out of harm’s way anything precious that might be damaged by contact with the public, or anything sharp that might irritate its skin.”
—Virginia Woolf (1882–1941)
“Such writing is a sort of mental masturbation.... I don’t mean that he is indecent but viciously soliciting his own ideas into a state which is neither poetry nor anything else but a Bedlam vision produced by raw pork and opium.”
—George Gordon Noel Byron (1788–1824)
