Please explain step by step and indicating the reason behind any required procedure for the following: Suppose you have a $5000$ byte IP datagram $($including the $20$ byte IP header$).$ The datagram must be fragmented to be transmitted over a network with a maximum transmission unit $($MTU$)$ size of $1500$ bytes.

$1)$ How many fragments will be generated?

$2)$ What will be the size of each fragment?

$3)$ What will be the value of the Fragment Offset fields and the "More Fragments" $($MF$)$ bits for each fragment?

Additional information:

The IP header is $20$ bytes in size and is included in each fragment.

The Fragment Offset field indicates the position of the fragment in the original datagram in terms of $8$byte blocks.
