The Role of Technology in Daily Life
The computer is no longer something new and special to many people nowadays,
because many families now have at least one computer in their homes. When most
people think of a computer they think of the monitor, the tower, and the small pieces that
come with it, like the keyboard and mouse. In fact, a computer can be broken down into
four distinct categories, which include the output, input, CPU, processor, and the power
The term "output" consists of all components that display words and graphics so

users enter commands and text. There are many other forms of input as well.
Nonetheless, many people just don't realize them, or are too lazy to classify them. For
instance, the mouse belongs to input, since it provides a floating pointer on the screen so
that the users can access commands faster and easier. The scanner is another form of
input, because it acts like a photocopier, except it scans the image and makes it onto the
computer screen instead of onto a piece of paper.
The CPU, Central Processing Unit is probably one of the most important category
of the five . As the name implies, it is the soul of a computer, very much alike the human
brain. For some weird reason, people often call the CPU a computer. This is incorrect,
the word computer is just a general term which must always include all the
five categories in order to operate. Perhaps the components of a...
