I've been hearing a lot of buzz about the Y2K bug. What is it?

The Y2K bug was a problem that was supposed to occur on January 1, 2000. It was caused by computers that were designed to use only two digits for the year. If you had a computer in the early 1900s, it would have used four digits for the year. So if you put the number "1900" into a computer today, it might not be able to handle it because it wasn't expecting it.
