All these definitions are distinct and important. If one system has an MTTR of 24 hours and another has an MTTR of three days with equal time between failures, the first system is more valuable because its availability is higher. MTTF measures the reliability of a network and durability of its hardware. So, what is MTTR?

By definition, a distributed system is any system that comprises of multiple components on variety of machines that work together to appear as a single, organized system. Although the definition may seem straightforward, in the real-world, a distributed system is one of the most complex environments to understand, manage, and monitor.

An example of a specification is the correct operation of the hardware of a microprocessor. An SDC is the worst possible outcome of a fault, as it can have an arbitrary impact on the correctness of software running on the hardware.

The answer is hardware interrupts.
