The information in this ebook on various aspects of computers, peripherals and related subjects is organized into 21 chapters of about 500-600 words each. I hope that it will interest those who are interested in computers, the Internet, peripherals, electronics and using them in a practical fashion. As an added bonus, I am granting you permission to use the content on your own website or in your own blogs and newsletter, although it is better if you rewrite them in your own words first.
