Question 4
(a) (i) Identify Figure 1.
(ii) Name the parts labeled I. J. K and L in Figure 1.
(b) (i) Define the documentation stage in Program Development Life Cycle.
(ii) List three characteristics of a good computer program.
Observation
The expected answers were:
(a) Identification of Figure 1
i. Flowchart diagram
ii. Name of parts
(b) (i) The documentation stage
Documentation stage involves writing a manual that provides an overview of the functionability, tutorial, in-depth explanation of major program features,reference documentation of all program commands and thorough description of error messages generated by the program.
OR
It is a stage that contains a write-up showing the programspecification, operational
manual and user manual
(ii) Characteristics of a good computer program
- Accuracy
- Readability
- Maintainability/Durability
- Portability
- Efficiency
- Generality/Versatility
- Cost effective
- Reliability
- Minimal complexity
-Loose coupling
-Reusability
- Security
- Suitability
- Replaceability
- Installability
- Clarity
- Flexibility
The question required candidates to identify parts of a flowchart, define documentation stage in program development life cycle, list characteristics of good computer program.
The Chief Examiner reported that candidates showed good knowledge of area tested.
