Everyone knows how great computers have become, and also how small, hand held cell phones are becoming, due to advances in computer technology by way of computer chips. Now here is some interesting information on how a computer works and how a cell phone works, the hardware, the communication systems that make this possible, and of course the computer technology behind it all.
How PCs Work
"When you mention the word "technology," most people think about computers. Virtually every facet of our lives has some computerized component. The appliances in our homes have microprocessors built into them, as do our televisions. Even our cars have a computer. But the computer that everyone thinks of first is typically the personal computer, or PC."

How Cell Phones Work
"What is amazing is that all of that functionality -- which only 30 years ago would have filled an entire floor of an office building -- now fits into a package that sits comfortably in the palm of your hand!"
