why readabilities only for hardware not software
Fault tolerance
Should be obvious. Hardware faults are problems with the hardware. Software faults are problems with the software. Hardware = physical components of the computer (i.g. motherboard, hard drive, power supply). Software = computer programs
The difference between software fault and software failureSoftware failure occurs when the software does not do what the user expects to see.A software fault, on the other hand, is a hidden programming error. It becomes a software failure only when the exact computation conditions are met, and the faulty portion of the code is executed on the CPU. This can occur during normal usage. Or, when the software is ported to a different hardware platform. Or, when the software is ported to a different compiler. Or, when the software gets extended.
A new software reliability model is developed that predicts expected failures (and hence related reliability quantities) as well or better than existing software reliability model this works for cases where the operational profile remains unchanged, and where corrections (perfect or imperfect) are made when a failure is observed

Reliability is not measured. Reliability is an estimation, typically probablistic.
Hardware RAID uses a dedicated controller card to manage the RAID array, offloading processing from the host system and often providing better performance and reliability compared to software RAID. It typically supports advanced features like battery-backed cache and can handle multiple drives more efficiently. Additionally, hardware RAID can offer greater compatibility with various operating systems and improves data recovery options in case of drive failure. However, it may be more expensive and less flexible than software RAID solutions.
hardware, or software failure, more than likely not a virus.
We do Software testing for many reasons. Here are just some of those. 1. To check the reliability of the software. 2. To be ensured that the software does not contain any bug which can become a reason for failure. 3. To check the software was made according to its specification. 4. To check that the software meets its requirements. 5. To check that users are capable of using the software. 6. To check software works with other software and hardware it needs to work with
Failure of what component.
System redundancy refers to the inclusion of additional components or systems that serve as backups to ensure continuous operation and reliability in case of a failure. This can involve duplicating hardware, software, or network resources to prevent downtime and maintain service availability. By implementing redundancy, organizations can enhance fault tolerance and improve overall system resilience against unexpected disruptions.
