When I describe this column I say that I teach a bunch of bright first-graders about gadgets and computers.

Before you write a nasty note --- using a crayon and block letters --- let me explain. This column isn't intended for computer experts, nor is it aimed at advanced hobbyists. Some from each group read the column, and I'm glad. However, my intention is to help those who need and want to use technology but have no desire to build computers, write software or become the expert on your block.

That's why I think of this as a first-grade class. And since new members join our class at times, we often come back to basic topics such as security, tips on computer buying, virus problems and scams.

But we seldom have a test, and that shames me. So get out your pencils. It's pop quiz time. It's fine to cheat. (Otherwise, how will you ever graduate from the first grade?) All these questions have been answered in columns printed during the past six months. I'll put the answers at the bottom.
