A relatively small set primitive constructs that can be combined in a relatively small numbers of ways is called what?
Orthogonality
What has few constructs, a small number of primitives, and a small set of rules for combining them?
Simplicity and Orthogonality
The testing for type errors refers to what?
Type Checking
When considering computer architecture influence what is the basis for imperative languages?
- Variables model memory cells
- Assignment statements model piping
- Iteration is efficient
What is the Fetch-Execute-Cycle?
- initialize the program counter
- repeat forever
- fetch the instructions pointed by the counter
- increment the counter
- decode the instruction
- execute the instruction
- end repeat
The common type of computer architecture that stores both programs and data in a common memory is called:
Von Neumann

1: fetch
2: decode
3: execute
