Suppose that the go-back-n protocol with m = 3 and the sending window of size 7 is used to send packets. let & = 31 modulo 2., / = 35 modulo 2., and / = 33 modulo 2..
a. what are the sequence numbers of data packets in transit?
b. what are the acknowledgement numbers of ack packets in transmit?
c. if the sender’s process sends two more data packets to the sender’s transport layer and one ack packet is received from the receiver’s transport layer, what are the updated values for & and / ?

Write a defining table and then a program that determines if you can sleep in or not. your program should get all its input from your computer’s clock. on all weekdays (monday through friday) that are not holidays, your program should output “get up! ” on all other days (weekends and holidays), your program should output “sleep in.” the three holidays that your program must check for are january 1 (new year’s day), july 4 (u. s. independence day), and december 25 (christmas). you don’t need to include other holidays in your program because most other holidays do not occur on a fixed day each year.
