12. Activity – assignment related
Produce an extensive table which
Maps in detail different systems to different environments
Provide a descriptive analysis to support the mapping
Use the characteristics and environments from the slides but add specific examples
For instance you might suggest an SoC CPU with only tape storage for a mainframe
And reference, reference, reference
