Assume a cache with the following properties: 32 bit address, 4 entries, directly mapped, 4 Byte cache blocks. Assume that at the beginning of the following sequence all cache entries are invalid. How many valid cache lines are in the cache after executing the following sequence of cache accesses. The following are byte addresses in hex. Address Sequence: 0x0FF0, 0x0FF1, 0x0FFF, 0x0F0F, 0x0D0F, 0x0DFF

so much for the extra points :

control f

then locate the name

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.
