System Analysis And Design MCQ Questions & Answers | Computer Science

Option A: Input
This symbol in a flowchart is used to represent data or information entering into the system. It typically signifies where data is received from an external source or user input.

Option B: Output
The Output symbol in a flowchart denotes where data or information leaves the system. It represents the points where processed or calculated results are displayed or outputted.

Option C: Process
The Process symbol in a flowchart is used to represent a calculation or computational task. It signifies any action or operation performed on data, such as arithmetic calculations, data manipulation, or logical operations.

Option D: Start
The Start symbol is used to indicate the beginning point of a flowchart. It marks where the execution or flow of processes starts within the system or program.

Option E: Stop
The Stop symbol marks the endpoint of a flowchart. It represents where the execution of processes or tasks within the flowchart comes to an end.

Conclusion:
Among the given options, the symbol used in a flowchart to represent a calculation task is the Process symbol (Option C). This symbol is specifically designed to indicate any computational or processing tasks performed on data within the flowchart's sequence of operations. Therefore, the correct answer to the question is Option C: Process.

The correct option is "making sure that the new programs do in fact process certain transactions according to Specifications".

Sequential or series testing is a type of software/system testing where the system is run step by step with specific sets of data to ensure that it behaves exactly as defined in the specifications.

The purpose of this testing is to confirm that the new programs correctly process transactions in sequence and produce the expected results, validating accuracy and consistency.

Why not the others?

"Running the system with live data by the actual user" refers to acceptance testing, not sequential testing.

"Checking the logic of one or more programs in the candidate system" refers to desk checking or program logic testing, not sequential testing.

"Testing changes made in an existing or a new program" is regression testing, not sequential testing.

"None of the above" is incorrect because Option B matches the definition of sequential or series testing.

Therefore, the most accurate answer is Option B.
