Welcome to the Guru42 Universe.

A Universe not only of sight and sound but of mind; a journey into a wondrous Universe whose boundaries are that of imagination.


The Universe starts here with a discussion of the power and responsibility of using technology wisely.

The Guru 42 Universe was created to stretch your mind beyond the buzzwords and fanboy geek speak, to see things in a different perspective.

Since 1998, the technology websites of Tom Peracchio have attempted to provide self help and tutorials for learning basic computer and networking technology concepts, maintaining the theme, "Geek Speak Made Simple."

Many of the ideas and inspiration for the websites of the Guru42 Universe date back to Tom's personal use of desktop computers and online services back in the 1980s. Tom began actively speaking and writing on both business and technology issues since before the internet was widely used by small business. Exploring PC telecommunications and its role in business lead to Tom's first article for a regional business journal on how the average business could use Computerized Bulletin Board Systems (BBS) as a tool for customer service.
