Can CPU make mistake?

Unless your hypothetical computer has an extremely small amount of memory, it is unlikely to work without any mistake for 5 years. Note however that some of the bit flips may occur in parts of the memory that you are not using, in which case they won’t affect you.

How does a CPU do calculations?

To perform a calculation, program data is loaded from system RAM into the control section. The control section reads two numbers from RAM, loads the first one into the ALU’s instruction register, and then loads the second one onto the bus. Meanwhile, it sends the ALU an instruction code telling it what to do.

Does CPU lose performance over time?

In practice, yes, CPUs get slower over time because of dust build-up on the heatsink, and because the lower-quality thermal paste that prebuilt computers are often shipped with will degrade or evaporate. These effects cause the CPU to overheat, at which point it will throttle its speed to prevent damage.

Can computers make calculation errors?

Yes. Aside from people programming computers wrong or computers lacking the resources to correctly perform a calculation, they can produce errors as a result of decay, where their wiring or memory breaks down.

Do computers degrade over time?

Originally Answered: Do computer parts degrade in performance over time (ignoring software and becoming inferior)? No, they do not degrade. Seriously, they either keep working as designed, or they fail completely. They do not slow down.

Can a CPU last 20 years?

It will last years, at the very least maybe 5–10 years but probably over 20 years. There is nothing to worry about a CPU breaking anytime before you will need to upgrade it due to obsolescence.

Are computers just big calculators?

General Differences. Calculators are single-purpose devices that perform mathematical operations input by the user. Computers are calculators that have vastly expanded capabilities, and are often called “general purpose computing devices.” Computers can do everything a calculator can do.

What is considered a large relative error?

Relative error is defined as the absolute error relative to the size of the measurement, and it depends on both the absolute error and the measured value. The relative error is large when the measured value is small, or when the absolute error is large. Relative error has no units.
