Question	Answer
Types of CPU Architecture?	There are two main types: Von Neumann Harvard Architecture
What is "Von Neumann Architecture"?	Von Neumann architecture involves a single memory storage followed by a processor.
Pros and Cons of Von Neumann?	Cons: -The instructions and data are stored in the same format. - Follows a linear fetch-decode-execute cycle - Cannot use pipelining Pros: - Seperate buses are not required - "Flexibility": Data space can be used for instructions, therefore no maximum ratio of division.
What is "Harvard Architecture"?	Harvard Architecture involves 2 separate storage locations for instructions and data and includes the processor.
Pros and Cons of Harvard Architecture	Pros: - Can support pipelining - No complications and mix-ups between instruction and data Cons - Data and Instruction have a max capacity that may not be able to be expanded.
