Over the past decade, the world as we once knew it has completely changed.  If you go back before the development of the World Wide Web, corporations conducted businesses primarily in their own region.  To reach out beyond that territory, hub offices or plants were created all around the country, and sometimes, overseas.  As you can imagine, this meant that companies were limited into the number of products or volume of services they could sell.

Wireless networks have changed the way in which computers are set up, making things much easier and better.  First, the definition of wireless networks is a specific type of network that uses high frequency radio waves or infrared instead of wires to communicate between two computers.  The result is increased mobility and easier access to data.

Flash memory is a non-volatile memory device that can be erased at signal levels typically found within a PC.  This way, the contents can be reprogrammed, as you like without you having to open the computer, pull out the chips, and replace them.  After flash memory has been reprogrammed, you could remove the expansion board that it is mounted to, plugging it into another computer if you want.
