Given this instruction mix and the assumption that an arithmetic instruction requires 2 cycles, a load/store instruction takes 6 cycles, and a branch instruction takes 3 cycles, find the average CPI.

2.6

Explanation:

I am assuming that for any given program, that 70% of it's executed instructions happen to be arithmetic, another 10% happen to be load/store, and finally, a 20% happen to be branch. If so, then I can say

Average CPI =

3Σi=1 Percentage of instructions * CPI

Average CPI = (0.7 * 2) + (0.1 * 6) + (0.2 * 3)

Average CPI = 1.4 + 0.6 + 0.6

Average CPI = 2.6

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.
