64 Bit OS versus 32 Bit OS?

I just had a call from a customer looking to upgrade to Vista but was unsure of the differences she was offered. The store in which she was going to purchase the software offered her Windows Vista Premium in either a 32 bit or 64 bit set-up. When she asked what's the difference, she got a blank stare. So she called On-Site for the answer.

So here's the scoop... Since the introduction of Intel's 386 platform, or approximately the last 10 years, 32 bit computing has been the standard. This bit rating of the processor determines the largest numerical number that processor can handle. The largest number that can be processed in a single clock cycle will be equivalent to 2 to the power of the bit rating.

On-Site gets quite a few calls regarding wireless networking. One of the more frequent service calls we run is associated with wireless drop out, or lack of coverage in homes and small businesses. If you have ever experienced an area of your home or office that you were unable to connect to your network do to poor signal quality or no signal at all, or had been surfing along the Internet and then all of a sudden, wham, no signal, you have experience this condition. Typically when this happens, if you move a little bit, or wait a few minutes, your connection is back. Most of us assume that the service provider is having some sort of an issue. In 95% of cases this actually isn't true. More likely that not, you have experience drop out from your own router.
