MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -2) Reliability is measured by considering processing speed, response time, resource consumption, throughput, and efficiency. 3) Refinement is actually a process of elaboration. 4) Which classes implement lower-level business abstractions required to fully manage the business domain classes.

Detailed explanation-2: -Reliability is measured by considering processing speed, response time, resource consumption, throughput, and efficiency.

Detailed explanation-3: -∴ Hence the correct answer is (A), (B) and (C). Software reliability, like hardware reliability, is defined as the probability that the software system will work without failure under specified conditions and for a specified period of time.

Detailed explanation-4: -Correct answer to your question is C. Unlike hardware, software doesn’t wear out with use and can improve with age if faults are properly corrected during the software support phase. Exhaustive testing is the most practicable way known to improve software reliability levels.

Detailed explanation-5: -Software reliability is the probability of failure-free operation of a computer program for a specified period in a specified environment. Reliability is a customer-oriented view of software quality. It relates to operation rather than design of the program, and hence it is dynamic rather than static.
