• There are several good programming tests on this site, but this shall be the first (or the best, if I missed it) to test your knowledge of the internal workings of your personal computer. Sure you can bring down some numbskull's server with just code, and call yourself a hacker, but how do you expect to make any money unless you know the true basics of computing? This test will test your knowledge of the mysteries of the "black box." You will be penalized for guessing, so skip it if you can't narrow it down at all.
