First day of class

Tomorrow my classes begin. My first class in graduate school is a Technical class about computers and webpage design and other software that manages information like spreadsheets. Glancing through the textbook is like reading a foreign language and rather intimidating. I will probably ask a lot of "stupid questions", like "What exactly is the difference between RAM and ROM?"and everyone will wag their head in disbelief. 

I suppose this is the best class to have right off the bat to get me up to speed with technology. My undergraduate studies hardly required such computer savvy and even if it had it would be outdated by now.
