pipelining and parallelism in the context of computing

a) Write an assembly program using MARIE's assembly Instruction set that prompts the user to enter a non-negative integer that is less than 10. The program should include a subroutine that keeps prompting until a valid value is obtained. When a valid number is entered, it will be displayed. (Hint: Use JNS & JUMPI instructions to implement the subroutine)

N.B: You should include the MARIE code in your Answer, with an explanation of each instruction in your code beside it. Example: Subt One /Subtract 1 from AC

b) Add a screenshot of the simulation, showing the result (A screenshot of the MARIE Simulator window after running the program). Instructions: - Use “ORG” instruction to start your program at address equivalent to 25610. - Use your last university ID number to input the value of X. For example, if your ID is1915161678234, then you will use the number 4 as the value of x. - Do not forget to change the representation of the Input and Output windows in the simulator to Decimal.

1.      Suppose end system A wants to send a large file to end system B. At a very high level, describe how end system A creates packets from the file. When one of these packets arrives to a router, what information in the packet does the router use to determine the link onto which the packet is forwarded? Why is packet switching in the Internet analogous to driving from one city to another and asking directions along the way?
