Introduction to the PC

The computer consists of at least one processing element, a central processing unit (CPU), and some form of memory. This allows the processor to carry out mathematical and logic operations. While mechanical analog computer have been around since medieval times and were used extensively during WWII, the advent of the personal computer is still relatively new. To understand where computer technology is going, one must also understand where it has been.

Your neighbor has asked you to set up a home computer system. He plans to use the system for Internet searching, correspondence through email and social media, and to play games. Occasionally, he will have to prepare documents or formal letters to send electronically. You will need to analyze the environment for the system and determine the requirements.

In order to determine what computer system your neighbor will need, you will need to determine which system and hardware will best meet his needs.
