13.1 Aspects of software development

Question 1

What is analysis in computer science?

Answer 1

The definition of a problem and the establishment of the system requirements and data models necessary to solve the problem, after the necessary research

Question 2

What is design in computer science?

Answer 2

The planning and specification of the data structures, algorithms, modules and interfaces necessary for the solution to the problem.

Question 3

What is implementation in computer science?

Answer 3

Writing the code necessary to create the algorithms and data structures from the design phase, in an iterative process of prototyping

Question 4

What is acceptance testing?

Answer 4

A component of testing with the intended users to ensure the intended solution is met

Question 5

What is boundary data?

Answer 5

Test input data that lies on the boundary of the system’s expected range

Question 6

What is erroneous data?

Answer 6

Test input data that lies outside of the system’s expected range (incorrect data)

Question 7

What is normal data?

Answer 7

Test input data that lies within the system’s expected range. It should return the expected output.

Question 8

What is testing in computer science?

Answer 8

Running implementations to check for the presence of errors using selected test data covering normal (typical) boundary and erroneous data.

Question 9

What is an evaluation in computer science?

Answer 9

The judgment of the system to check if it has met the required criteria to be an effective solution to the initial problem.
