A student was in the CIL Lab taking the Computer Systems test today, which covers parts of a computer, security, networks, and the like. He would fail, study for a couple minutes, and take it again.
After the third fail in a row, I asked him if there was anything he wanted to talk about. He just asked how up to date the test is and brought up a particular question as an example. It asked about how current processor speed is measured. He was answering megahertz, since he was assuming the test was way out of date. You think it's that out of date? It's been since about 2001 or 2002 that computer manufacturers passed the gigahertz mark.
I mean, my phone, which is about a year old, only runs about 200 MHz, but it's a phone, not a full-fledged computer. No one cares about the processor speed of their phone (other than perhaps me, since I actually know what it is). But when was the last time you were discussing a relatively new computer and quoted the speed in megahertz? Of course you don't remember, because it's been gigahertz for the past 6 or 7 years.
He passed it the fourth time, with his score jumping up about 15%, easily clearing the minimum required score.
