Achievement: Unless you try to do something beyond what you have already mastered, you will never grow. —Successories
In recent years, the growth of networks everywhere has accelerated as many organizations move into the international business arena and join the Internet community. This expansion continues to drive the development, refinement, and complexity of network equipment and software, consequently resulting in some unique issues and exciting advances. You rarely see an advertisement that does not contain the famous www prefix. In my hometown, one of the local news stations now displays the e-mail address of its reporters as they deliver the news! Is this the new economy in action, or is it just another example of too much information? At least the media are feeding on their own now!
Can you imagine modern business or life without computers, fax machines and services, e-mail, Internet commerce, automatic teller machines, remote banking, check cards, or video conferencing? Even more importantly, today's children think that these tools are commonplace and that business cannot be done without them when they get to our age. I hate to admit it, but I can clearly remember a time without the Internet and when Novell ruled the office; however, nothing stands still in our industry, and some of us have known that for quite a while.
Gordon Moore of Intel made an interesting observation in 1965, just 6 years after he invented the first planar transistor. He observed that the "doubling of transistor density on a manufactured die every year" would occur. Now almost 40 years later, his statement has become known as Moore's law, and it has continued to hold true. According to Intel
There are no theoretical or practical challenges that will prevent Moore's law from being true for another 20 years; this is another five generations of processors.
In 1995, Moore updated his prediction to indicate that transistor density would double once every two years. Using Moore's law to predict transistor density in 2012, Intel should have the capability to integrate 1 billion transistors on a production die that will be operating at 10 GHz. This could result in a performance of 100,000 MIPS. This represents an increase over the Pentium II processor that is similar to the Pentium II processor's speed increase over the 386 chip. That is impressive considering the sheer number of transistors on a chip that you can hold in your hand! Figure 1-1 depicts Moore's law.
