Match the terms related to Software Configuration Management (SCM) in List – I with the descriptions in List – II. Codes :List – I List – II I. Version A. An instance of a system that is distributed to customers. II. Release B. An instance of a system which is functionally identical to other instances, but designed for different hardware/software configurations. III. Variant C. An instance of a system that differs, in some way, from other instances.
I-C, II-A, III-B
Software configuration management (Sommerville) distinguishes three kinds of system instance: versions, variants and releases.
I. A version is an instance of a system that differs, in some way, from other instances; new versions may add functionality, fix faults or improve performance (I-C).
II. A release is an instance of a system that is distributed to users outside the development team, i.e. to customers (II-A).
III. A variant is an instance that is functionally identical to other instances but is built for a different hardware or software configuration, such as another operating system (III-B).
The codes that map version to the functionally identical description or variant to the distributed description confuse these terms, so only I-C, II-A, III-B fits all three definitions.
I-C, II-A, III-B option is correct.
