Question

The average amount of time until the next hardware failure is known as __________.
A) ​​mean time between failure (MTBF)  
B) ​mean time to diagnose (MTTD) 
C) ​mean time to failure (MTTF) 
D) ​mean time to repair (MTTR)

Mean time to failure (MTTF) is the average amount of time until the next hardware failure. MTBF (mean time between failure) is a similar metric, but it includes the time it takes to repair the hardware, while MTTF only measures the time between failures. MTTD (mean time to diagnose) and MTTR (mean time to repair) are different metrics that measure the average time it takes to diagnose and repair a hardware failure, respectively.
