Question

Expendability, recoverability, reparability, cost designator (ERRCD)

a) Factors in software development
b) Principles of hardware engineering
c) Criteria in system design
d) Measures in network security

Answer 1

Expendability, recoverability, reparability, and cost designator (ERRCD) are criteria in system design that evaluate the quality and feasibility of a design.

Step-by-step explanation:

Expendability, recoverability, reparability, and cost designator (ERRCD) are criteria in system design. These factors are used to evaluate the quality of a design and determine its suitability for meeting desired needs within realistic constraints.

Expendability refers to the ability to replace or add components to a system without significantly impacting its functionality or performance.

Recoverability pertains to the ability to restore a system to its normal functioning state after a failure or disruption.

Reparability involves the ease and cost-effectiveness of fixing or repairing a system or its components.

Cost designator (ERRCD) is a measure used to assign a cost value to different design options, taking into account factors such as materials, manufacturing processes, and labour.
