$1.$ Suppose we wish to send a $500$MB file $($note that MB means megabytes, and $1$ byte $=8$ bits$).$ The maximum segment size $($or datagram size for UDP$)$ along the path is $1300$ bytes, so no segment$/$datagram may exceed $1300$ bytes in length

a$.$ How many UDP datagrams must we send to send the entire contents of the file $($assume no loss or corruption of packets$)?$

b$.$ How many TCP segments must we send to send the entire contents of the file $($you may ignore segments solely acknowledging receipt, as we do not know for sure how often the recipient will send them, but do not forget the TCP $3-$way handshake$)?$
