Right, so computers can be basically be broken down into two ideas: the physical and conceptuality.

The Physical

The Physical idea of the computer refers to what it can do. This means the limits of its hardware, and software. Anything that is physically related the computer, parts, accessories etc. all relate to the physical idea of a computer. Example: a disk containing Word

Conceptuality

Conceptuality refers to the capacity to which the computer can fulfill. This concept goes past the physical limits and applies to the ideas that the computer is capable of processing and handling. This is the sum of the parts and their overall potential. Example: The program Word has the potential of communicating will people all over the world, and yet this potential is sealed within a tiny disk.

Life Example 

The most concrete example I can give relates to the human itself. Physically, we more or less the same, with arms, legs and a head. However, the sum of our parts and our potential is very different. We are all individuals and have many differences and similarities, and yet we are all encased in essentially the same body. The difference between one person can be seen through the physical, and yet the conceptuality of each one of us is the more important part of the two halves.
