Evaluating a Computer System
Judging the effectiveness of a computer system has taken on a new dimension in the past few years, if for no other reason than the wide range of computer systems from which the user can select. It is, therefore, important that we investigate the criteria that should be considered in making this important decision. Probably the obvious criterion to be considered when one purchases a computer system is speed. The value of a computer is directly related to its speed, and a computer’s speed is typically measured in gigahertz (GHz). A gigahertz is one billion cycles per second, and the more the gigahertz you have to work with, the faster your computer will run. However, computer manufacturers are starting to drop the gigahertz rating from computers because there are so many other factors that determine a computer’s speed (Phillips 243). Another important consideration is memory. Software programs continue to expand and need more memory to run on today’s computers. If a computer does not have sufficient memory, your computer will process slowly or not at all. When purchasing your new computer, do not settle for anything less than 8 to 12 GBytes of Dual or Tri-Channel memory. Flexibility is also important because of the rapid turnovers of hardware and software in the computer industry. The flexibility of a computer system is important for two reasons: to accommodate a variety of programs and to permit expandability. Hundreds and possibly thousands of software packages are available today to meet the needs of computer users. The computer you purchase must be able to accommodate this variety of software and flexible enough to change with the increasing sophistication of software packages.
