The line between computer systems can be
extremely vague. A powerful entry level system can double as an low end
business system, or a gamming system can be identical to a low end
workstation. In fact, some equipment manufactures may refer to their
business systems as workstations. Some components on a computer in any class
can be installed on all systems. For example, a manufacture may use the same
RAM on the entry level system and the gaming system. You will want to pay
particular attention to system's CPU and Video. Sometimes it the amount of
hard disk space or the addition of a better video adapter that moves a
system from one class to another. Please keep in mind that the tables below
show the minimum configurations.
Entry level systems are the most common systems for
home and general use.
These systems are often powerful enough to run standard office software, watch
DVD movies, surf the internet, send and receive email, as well as run home and
small office accounting software. As of the date of this article, the minimum
configuration for an entry level computer system is as follows:
