As each us of look at our lives, do we realize the importance of these electronic mechanisms we call computers? I shall now endeavor to elaborate upon how these mind tools have, and continue to affect me.
Every morning, I awake to the awkward squawking of my alarm clock. Much to my dismay, I groggily smack the ‘off’ button and crawl out of bed. My first encounter of the day has just occurred.

Moving on, I begin to prepare a meal. In my kitchen are several devices that are in some fashion controlled by computers. For example, let us examine the microwave. The microwave contains a microprocessor and memory. These work together to maintain an accurate clock, as well as an efficient food preparatory system. Information is input to the microwave by use of the external touch pad, this data is stored and processed in the memory and processor as it completes it’s task.
Another activity that I may do is listen to a compact disc. CD players have decoders that interpret the microscopic pits and dents on the surface of a CD into music. This decoded information is then converted into sound and amplified to produce the desired sounds.
