In which of the following situations would a straight-through cable be used? Note: Count the crossover connections. You need an odd number of crossover connections in order to have communication. If you have an odd number of crossover connections to start with, then you use a straight-through cable. A PC NIC has a straight-through port. A hub has crossover ports, except for the daisy-chain port. A switch has crossover ports. A router has straight-through ports. switch to PC router to router router to switch router to PC switch to hub PC to hub switch to PC router to router router to switch router to PC switch to hub PC to hub
