I work for private individuals and for a government agency, providing assistive technology training as well as general technology training. Since so much of what is done now is on a smart phone or a tablet, I use the word technology rather than computer.
If you bought a new smart phone and can’t quite get the hang of it, I’ll give you a lesson or two (or more if you wish) to help you understand how to use this new tool. Most people only need a little bit of help to learn the basics.
