Modules

 Task State Segment (TSS)
 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.
 
 Global Descriptor Table (GDT)
 Is used 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.
 
 Interrupt Descriptor Table (IDT)
 Is a data structure used by the x86 architecture to implement an interrupt vector table. The IDT is used by the processor to determine the correct response to interrupts and exceptions.
 
 Interrupt Service Routines (ISRs)
 are software routines that hardware invokes in response to an interrupt.
