b$)$ For a Pentium $4$ working in the protected mode $,$ the descriptor number $2$ is shown in the next figure, contains a base address of $00280000$ H $,$ a limit of $61000H,G=1,D=0,AV=1$ where the access rights byte contains FFH$,$ Perform the following:

i$.$ What are the starting and ending locations that are addressed by this descriptor?

ii$.$ Fill in the shown descriptor using the given data.

iii. Is the descriptor describes a data segment or a code segment.

iv$.$ A segment register has $001$ A H$,$ can this segment register access this descriptor? Why?
