Computer Studies Paper 2, WASSCE (SC), 2019

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.
