9.16 a. How many trap service routines can be implemented in the LC-3? Why? b. Why must a RET instruction be used to return from a TRAP routine? Why won’t a BR (Unconditional Branch) instruction work instead? c. How many accesses to memory are made during the processing of a TRAP instruction? Assume the TRAP is already in the IR.

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
