This book is about the structure and function of computers. Its purpose is to present, as
clearly and completely as possible, the nature and characteristics of modern-day computers.
This task is a challenging one for two reasons.
First, there is a tremendous variety of products, from single-chip microcomputers
costing a few dollars to supercomputers costing tens of millions of dollars, that can
rightly claim the name computer.Variety is exhibited not only in cost, but also in size,
performance, and application.
Today it seems like everyone has a digital camera and that digital
photography has been around forever. There are hundreds of models
of digital cameras available, and finding film is getting to be more and
more difficult. But, this really isn’t the way it always was.
In 1992, I was working at the Newport Beach Police Department. The department
bought a Kodak DCS 200 digital camera that provided a whopping 1.5 million pixels and
cost around $10,000. It didn’t use a memory card, but it had an internal computer hard
drive and a SCSI connection to download photos to the computer.
