Tables like GDT, IDT, etc.

The tables that an operating system needs to implement in x86 IA32 architecture depend on the specific requirements of the operating system. However, there are some tables that are commonly used in operating systems for x86 IA32 architecture. Here are some examples:

GDT: The Global Descriptor Table (GDT) is a data structure used by the x86 architecture to implement the segmentation system
It contains descriptors that define the base address, limit, and access rights of each segment
The GDT is used to provide address management and protection

IDT: The Interrupt Descriptor Table (IDT) is a data structure used by the x86 architecture to implement an interrupt vector table
It contains interrupt vectors that the processor uses to determine the correct response to interrupts and exceptions
The IDT is used by the processor to handle hardware interrupts, software interrupts, and processor exceptions

PDT: The Page Directory Table (PDT) is a data structure used by the x86 architecture to implement virtual memory
It is used to translate virtual addresses to physical addresses
The PDT contains page table entries that describe the attributes of each page in memory

PT: The Page Table (PT) is a data structure used by the x86 architecture to implement virtual memory
It is used in conjunction with the PDT to translate virtual addresses to physical addresses
The PT contains page table entries that describe the attributes of each page in memory

LDT: The Local Descriptor Table (LDT) is a data structure used by the x86 architecture to implement the segmentation system
It is similar to the GDT but is used for local segments
The LDT is used to provide address management and protection

TSS: The Task State Segment (TSS) is a data structure used by the x86 architecture to store information about a task
It contains information such as the task's stack pointer, privilege level, and I/O permissions
The TSS is used by the hardware task switch mechanism to switch between tasks

In summary, the tables that an operating system needs to implement in x86 IA32 architecture depend on the specific requirements of the operating system. However, the GDT, IDT, PDT, PT, LDT, and TSS are commonly used in operating systems for x86 IA32 architecture.
