What my concern was how in depth does the core exam go into? I mean, do you have to know all the different pins, speeds, etc for every possible socket, slot, CPU, memory type, etc....Is it necessary to know what each of the different colored wires coming from the power supply do, etc.... What I'm trying to figure out is how in-depth detailed can the A+ exam get?
