Exam Questions & Answers (Grade
A+)
Included a number of models
Could upgrade to a more expensive, faster model without having to
abandon original software
New models are introduced with improved technology, but retain
the same architecture so that the customer's software investment
is protected
Architecture has survived to this day as the architecture of IBM's
mainframe product line
Hierarchical system -
correct answer ✅Set of interrelated subsystems
Hierarchical nature of complex systems is essential to both their
