11. What are the attributes of good software ?
HP State JOA *
Correct : D
Explanation : Attributes of Good Software : Maintainability: Software should be easy to maintain, update, and modify over time. Adaptability: This is the extent to which a software system can adapt to changes in its environment. An adaptable software system can tolerate changes in its environment without external intervention. Effectiveness: Software becomes more effective when it is made according to standards.
12. Which model reduces the cost of development of software ?

Explanation: A prototype model is a systems development method that involves building, testing, and reworking a prototype until an acceptable outcome is achieved.
13. Which type of graphics create an image by combining basic drawings shapes likes lines, circles and curves etc ?
HP State JOA *
Correct : C
Explanation: Vector graphics are a type of computer graphics that create images using geometric shapes like points, lines, curves, and polygons. These shapes are defined on a Cartesian plane and connected by lines and curves to form other shapes.
14. Which software requirements generally relate to required system properties such as reliablity and response time ?
Correct : B
Explanation: Non-functional requirements define system properties and constraints e.g. reliability, response time and storage requirements. Constraints are I/O device capability, system representations, etc. Process requirements may also be specified mandating a particular IDE, programming language or development method. Non-functional requirements may be more critical than functional requirements. If these are not met, the system may be useless.
