Today most of the jobs mainly depend on either the creation or collection and distribution of information. This topic addresses the different advancements in computer technology and the various types of computers and their critical components. As each new computer generation improves on its previous generation, there has been a corresponding reduction in size (or miniaturization) of computer circuitry. In contrast to this miniaturization, the speed, power, and memory of computers have proportionally increased. Although this topic will describe the major developments of each computer generation, it is more important to consider how technology has influenced the development of current computer systems. The detailed description of computer evolution is discussed in the next title.
