Itec 1000 winter 2010 peter khaiter. Lecture 1 information systems and technology: basic concepts jan 4. System"s concept: definition a system is a set of components that interact with one another and serve for a common purpose or goal, systems may be abstract or physical. An abstract system is conceptual, a product of a human mind. That is, it cannot be seen or pointed to as an existing entity. None of them can be photographed, drawn or otherwise physically pictured. However, they do exist and can be discussed, studied and analyzed. A physical system, in contrast, has a material nature. It is based on material basis rather than on ideas or theoretical notions. Interrelationships: components, boundary, purpose, environment, output, constraints. System"s characteristics: a component is either an irreducible part or an aggregate of parts, also called a subsystem. The simple concept of a component is very powerful. The environment surrounds the system, both affecting it and being affected by it.
