Awebpage is a single html file that is of size 300,000 bytes. client has already received from host all bytes up to including byte 20,000. suppose host then sends two segments to client back-to-back. the first and the second segment contain 2000 and 1000 bytes of data respectively. client sends an acknowledgment whenever it receives a segment from host. in the first ack segment, the source port number is 5100.

in the second segment sent from host to client, what are the sequence number, and destination port number?
if the first segment arrives before the second segment, in the acknowledgment of the first arriving segment, what is the acknowledgment number, the source port number, and the destination port number?
if the second segment arrives before the first segment, in the acknowledgment of the first arriving segment, what is the acknowledgment number?

File account.java (see previous exercise) contains a definition for a simple bank account class with methods to withdraw, deposit, get the balance and account number, and return a string representation. note that the constructor for this class creates a random account number. save this class to your directory and study it to see how it works. then write the following additional code: 1. suppose the bank wants to keep track of how many accounts exist. a. declare a private static integer variable numaccounts to hold this value. like all instance and static variables, it will be initialized (to 0, since it’s an int) automatically. b. add code to the constructor to increment this variable every time an account is created. c. add a static method getnumaccounts that returns the total number of accounts. think about why this method should be static - its information is not related to any particular account. d. file testaccounts1.java contains a simple program that creates the specified number of bank accounts then uses the getnumaccounts method to find how many accounts were created. save it to your directory, then use it to test your modified account class.
