Buying this 458 pages, 9th Edition book is a better decision. The book is made with not superior paper, but its not bad at all. This is a great book but sometimes you will see that you can't find a word listed. For example, I can't find "software monitor", though they have listed hardware monitor. Then there are many words which are used in conjunction with databases like you cant find what is "pessimistic locking" and what is "optimistic". If anyone say that this book does not cover those topics to which I can't find the meanings and words, then I would say that why is the name of this book "The Computer Glossary. THE COMPLETE ILLUSTRATED DICTIONARY". I think when it's written that it's a COMPLETE DICTIONARY, then it should be complete. On the other hand the book features thousands of the terms and words used and the thing is like about this book is that there are diagrams which are in good quality printing, not at every page but worth enough. The excellent part is that there is a Multimedia CD-ROM version attached in the end of the book, which works great. You can just type the word and you will instantly get the meaning in real time. And all the contents in the CD are exactly those as are in the book. So if you just install the CD you will not even need to open the book. The CD comes with great printing and copy features, which I was not expecting. You can capture full screen or particular text and print it from the inside of the software. Just click on a picture (also listed in CD) and it will automatically prompt for printing. There are many other cool features also which should that it was developed by keen interest. Overall this is a good book and especially the CD but if more terms can be added to it, it can become "the excellent book". Now I have listed the cons and pros, its up to you people there to buy it or not. Enjoy reading!
