This pocket book contains clear and simple explanations and illustrations. This dictionary is probably ideal for the beginning to strong intermediate user who wants to have a reference at hand which gets to the point and leaves you feeling informed. It is well cross referenced, and strong on Internet terminology. Despite its very manageable size one rarely has occasion to look up terms not described in the dictionary. If you were to have just one computer dictionary then, for most users, this would be it. Users who feel very ill at ease with computer terminology may however want to consider 'Webster's New World Dictionary of Computer Terms', a equally good book which written with a slightly more experienced audience in mind.
This 'Barrons Dictionary of Computer and Internet Terms' is one of the best dictionaries of computer terms I've seen on the market. But as any other computer dictionary this one is also difficult to keep current and updated. The subject changes too much to have a good guide in printed form. But I love this book very much and recommend it to everyone.
