PREVIOUSLY
• Engineers and computer scientists design and build the world.
• Engineers visualize the things they design as systems.
• They design and build things in a systematic way.
• They use the engineering design process .
• They become engineers and computer scientists by
• studying at an accredited university
• becoming members of professional associations
• working on projects.
* Systems
PREVIOUSLY

• Abstraction
• Composability
• Engineering Design Process
• Overview of steps
• Identify and Define the Problem
• Requirements documentation
* Systems
WHAT IS A SYSTEM?
• a collection of interconnected components that have some function or purpose
• A system has an interface.
• Input/output
• A system has a behavior.
• Relationship between input and output.
• A system has a structure.
• The organization of its components.
