Question

How software and hardware reliability related to each other?

Answer 1

This paper presents the similarities and differences between hardware, software and system reliability. Relative contributions to system failures are shown for software and hardware and failure and recovery propensities are also discussed. Reliability, availability and maintainability (RAM) concepts have been broadly developed for software reliability than hardware reliability. Extending these software concepts to hardware and system reliability helps in examining the reliability of complex systems.

The paper concludes with assurance techniques for defending against faults. Most of the techniques discussed originate in software reliability but apply to all aspects of a system. Also, the effects of redundancy on overall system availability are shown.

Answer 2

Answer:

how software and hardware reliability related to each other.

Explanation:

Reliability of software can be defined as software which have no failure and working in a special time period with special environment. Working of software depends on instructions while hardware is a part of mechanical. Hardware and software both have major role in functional area of software. Because as we operate the software with hardware parts then if we find any errors in that case it effects the whole operation. the reliability of software is maintained until any fault finds in hardware which affects the path of the data. Reliability of software refers to the probability of a failing hardware part and the calculation of time for the maintenance of hardware parts. Physically errors are always find in software system.
