Yes.

It stands for mean time between failure so the greater the MTBF, greater will be the longevity or lifetime of the equipment between two successive failures

When determining how reliable something is, a benchmark called "Mean Time Between Failures" is often used. It's usually represented as "MTBF". That means, the average time that a component will operate continuously.

Relaxation time= mean collision time/(1-)

where A is the average angle of scattering that the electron makes with its initial direction

I mean... are you serious?

All electronics eventually fail, and that goes for laptop computers as well.

Expected life of most modern electronics is expressed as "Mean Time Between Failures", meaning that they project the AVERAGE (mean) amount of time that it takes before a specific device would fail. The time is typically calculated in thousands of hours.
