| should return to its caller from only one place which should be the last statement | ![]() | |
| procedure | provides procedural abstraction | ![]() |
| module | has high cohesion if related aspects of a system are kept together in this module, and unrelated aspects are kept out | ![]() |
| is implemented | ![]() | |

| procedural abstraction | has advantage when using a certain procedure, a programmer does not need to worry about all the details of how it performs its computations; he or she only needs to know how to call it and what it computes | ![]() |
| hides the details of procedures | ![]() | |
| component | may perform a special-purpose function such as the user interface for a particular system | ![]() |
