Our Telephone in Detail
|
|
Here is our telephone. To look at this as an object, let's put down some information about it. We will be classifying the information into three categories:
|
- Things that describe the telephone
- Things that we can do with the phone
- Things that the telephone tells us and that we can react to
Let's look at each of these aspects in turn:
|
Describe the telephone |
The telephone is gray |
|
What can we do with it?
|
We can place an outgoing call |
|
What can it tell us that we can react to?
|
Someone is trying to call us |
How It Works
The three categories that we have created in the left-hand column can be applied to any object. In fact, the best way to describe an object is to break down its characteristics into these three categories, and put information about your object into these categories. Any information that you have about a particular object can be included in one of these categories.
If you have another telephone that features all these characteristics, except that its color is blue, then we can describe your telephone by changing that one part of the description above. Moreover, this technique works for any type of object, both real world and software.
