I am new to the forum, and I hope this is the right place to start. After I separate from the military I plan to go to college for a degree in computer information technology. Until then I plan to learn as much as I can to give me a head start.

So with that being said a FRIEND of mine GAVE me a book to study for the A+ certification. I think this would be a decent start to get my feet wet and refresh on a few things I did know. I read different reviews on this certification as if it is worth it or not but personally I think it is.

Well for today I have a question about busses inside a computer. From my understanding it is a path which communication can travel down from the cpu to other components of the computer. Is this the actual circuitry (idk) that is etched in to the motherboard. I do not really know how to explain it. Or is it cables and wires?

If this is not the right place to come for this my apologies, it would be appreciated if you direct me to the right place. A bus is literally anything that carries data from one component to another inside a computer.  It could be a trace (or set of traces) on the motherboard (you can often SEE these going to/from the CPU such as between the CPU and RAM slots.  It could also be a CABLE such as your SATA cables to connect to your drives (this would be classed as a bus although it's not that common to call it that).  You also get buses inside the individual chips etched into the silicon.  EVEN connections to external devices can be classed as a bus (USB = Universal Serial Bus).Thank you. So traces would be the word I guess I was looking for. Alright well that really helped out a lot. The more I read the more I find out how much I did not know.
