The previous post defined the word "Abstraction" and the two worlds Real and Virtual.
The Virtual world (also called cyberspace)...
There are two kinds of resources in the virtual world - they are Hardware and Software.
Hardware and Software always co-exist in the Virtual world. If Software envelopes hardware we call it a "computer system". If hardware envelopes Software we call it an "embedded system". Software can be found in computer systems and embedded systems. Further, all Software can be categorized as Data and Programs. It is the interplay of data and programs that make Software so interesting.
During the ITIP we will explore Software (data and programs)
What is the Virtual world made up of? The answer is - artifacts. An artifact is anything made by human hand. Everything in the Virtual world is made by humans. Hence, everything is an artifact!
The ITIP is based on 4 fundamental concepts - Information, Instruction, Interface and Interactions - called the 4I model.
Any aspect of Software can be understood using the 4I Model. No, we will NOT be talking about the 4I model in the next post! We look at how Software is built...and in the process answer the question "what is Software?". Thanks for reading! See you next week...
