IT stands for "information technology."

That's the department assigned to fix your computer, the one you've called four times today so far. No, you're not an idiot. You're not some old dog with new tricks. What you are is growly and irritated but read "Keep Calm and Log On" by Gillian "Gus" Andrews, and your confidence will click in no time.

Though it's a relatively modern item, the computer that's sitting on your office desk is as old as time. Says Andrews, that device is a "revolution" and revolution means change. Now, you might not like change but there are ways to survive it, the first of which is to understand that nobody is "born" knowing how to use technology. Most people alive today, in fact, were born before today's technology was even available.

Next, know that most of the time, your computer probably isn't broken and neither are you. When you have problems, the likely issue is that software designers change things, move buttons, and eliminate features you used to like. It's not you, it just is. Practice and hands-on experience are always the keys to confidence, and that includes computers.

And yet – there's such a thing as becoming too comfortable with technology, perhaps to the point of addiction. Andrews says that what you see on social media and in search engines is designed to keep you clicking on the next thing and the next and the next. Learn how to stop the madness... and on the topic of search engines, know how best to use them.

Learn how to spot propaganda and news that's falsely reported. Find out why emojis and social media "stickers" can be a danger to relationships. See how to protect not just your devices but also what's in them. Learn why password changes are essential, why you should always allow devices to update, and why online trust is a very delicate thing.

Do you sometimes feel as though you're the only computer neophyte in the country? Does your smartphone make you feel dumb? Is your IT guy on speed-dial?

If so, this book was written specifically for you but "Keep Calm and Log On" is not without its issues.

True to its title, what's inside here includes plenty of assurance and affirmations because yes, tech today can be a major frustration. Author Gillian Andrews admits that, then she explains why and what you can do about the irritation you feel. That kind of hand-holding is appealing when you're beyond ready to toss your computer out the window, but that calm tone doesn't infantilize. Add in a lively bit of history and vintage artwork, and you've got a book that's almost fun to read just because.

Beware of this, however: Andrews' words on advertising and "profit motive" may rankle the businessperson who's can't seem to winnow the informational techno-wheat from the chaff. If you're able (and willing) to do that, though, and you're looking for something different and instructive, you'll find "Keep Calm and Log On" to be IT.
