Answer to Question 1

A

Answer to Question 2

Conversion by direct changeover means that, on a specified date, users stop using the old system and the new system is put into use.

Modular conversion uses the building of self-contained, operational subsystems to change from old systems to new in a gradual manner.

Distributed conversion refers to a situation in which multiple systems are converted at a single location. When that conversion is successfully completed, other conversions are done for other sites.
