hmmm.. still confuses  me,  but  what worries me is that i am a cs major and i have never heard about these  logarithmic terms before.  i know i have to  take  some  more  classes related to  logarithms,  but just so that i get an idea,  at what level do we need to know all these?

i am technically 3rd year (recently transferred), but from looking at my required classes, it will still take  me about 3 more to graduate.(BSc in CS)
