Q5) In a network protocol stack, the Link layer header is 14 bytes, the Network layer header is 20 bytes, and the Transport layer header is 20 bytes. Assuming your applicatiorn needs to transfer 100 Kbyte file over the network. If the maximum size at the Link layer is 1500 bytes (including headers), please find the followings: a) What would be the minimum number of segments that must be generated by Transport Layer? b) If you pay for 1 cent per 1 kilo bit transfer over the physical link to your ISP, what would be the cost of transferring 1 Kilobyte file over this link? (c if your application layer needs additional 20 bytes for security protocol, how does the figures in parts (A) and (B) changes, please calculate
