The correct answer is: B. Computers are essential for Systems Analysis
Systems analysis is the process of identifying and defining the need for a new or improved information system. It involves understanding the current system, identifying the problems with it, and developing a plan to solve those problems. Computers are essential for systems analysis because they allow analysts to collect and analyze data, model the system, and develop prototypes of the new system.
A parallel run involves two different systems running simultaneously to ensure that the new system is working properly. This is not always necessary, but it is often done for critical systems.
Flow of information in an organization can be vertical, horizontal, or diagonal. Vertical flow is the flow of information from top to bottom in the organization. Horizontal flow is the flow of information from side to side in the organization. Diagonal flow is the flow of information from top to bottom and from side to side.
A system flowchart is a graphical representation of a system. It shows the components of the system and the flow of data between them. System flowcharts are not a part of a program documentation package.
Therefore, the correct answer is: B. Computers are essential for Systems Analysis
