(b) Computer A sends 5 packets of data to computer B using Sliding Windows Flow Control• The transmission time (time to put on the network) for a packet of data is 1 'time units'• Transmission time for an acknowledgement is 0 ‘time units’ (they are very small)• The propagation time (time to travel through network) for any transmission is random(between 2 and 3 ‘time units’, you choose a random time for each packet andacknowledgement sent).• B's packet processing time is 1. B cannot process multiple packets simultaneously.• The initial window size is 3Draw a diagram to show how flow will be controlled while the data is being sent.After the installation of ZoneAlarm, what must you do before you use it?
