Fsb's

memorizing fsb'z will you need to know this for the exams of just the sockets and slots?

If FSB's are covered in the CompTIA objectives for the test (which they are) then you should have a basic understanding of them. Go to CompTIA's website and download the objectives for this test. That will give you the best idea of what you should know. Btw, my test had some of everything, so it's prolly a good idea to know it.
