ITPEC IP April 2023 Question 47
ITPEC IP April 2023 — Question 47 of 100
Screen layouts and form formats are defined during external design because they are externally visible interfaces. External design translates requirements into the system behavior and information presentation seen by users and connected systems, including screens, reports, forms, input-output items, and interface specifications.
Answer (a)
Why not others:
- (b) Internal design determines program structure, modules, internal data, and processing details
- (c) Programming implements the approved designs in code
- (d) Requirements definition identifies business needs and required capabilities at a higher level
Key rule: External design specifies what users and other systems see; internal design specifies how the implementation is organized.
