Solve the following problems from the text book (Silberschatz, 8th edition):
19: Distinguish between the client–server and peer-to-peer models of distributed systems.
22: What is the purpose of interrupts? What are the differences between a trap and an interrupt? Can traps be generated intentionally by a user program? If so, for what purpose?

9: Including the initial parent process, how many processes are created by the program shown in Figure 3.28?
13: Using the program shown in Figure 3.30, explain what the output will be at Line A.
15: Fibonacci sequence
18: echo server
Note: Source codes of programs in the textbook (including the date client and server) can be found here.
