If a file is in the trash can then its trashed. Some operating systems prevent trashing by asking for a login and password before trashing a file.

A computer which has been sensibly designed should refuse to trash itself as trashing itself would use itself to trash itself.

What are the uses of power system stabilizer?

PSS is a part of AVR in the form of an algorithm which detects and helps in damping of power system oscillations.


What steps does a well designed multiprocessing system follow when it detects that a processor is failing?

When a well-designed multiprocessing system detects a processor failure, it typically follows these steps: First, it initiates a fault detection mechanism to confirm the failure. Next, the system may isolate the failing processor to prevent it from affecting the overall system performance. Then, it reallocates tasks and resources to the remaining operational processors to maintain functionality. Finally, it may log the failure for diagnosis and further analysis, potentially triggering alerts for maintenance.

When the byte codes in a class file are invalid which one of the following must detect it?

When you have bytecode, the program is already compiled; so it would be the JVM which detects that.


What is the difference between radar level measurement and ultrasonic level measurement?

Radar is based on Microwave and detects the change in dielectric constant where as Ultrasonic is based on Sound Wave at high frequency (Ultrasonic Wave) and detects change in density of medium. Based on performance and accuracy Radar is a better solution than Ultrasonic. However for lower range liquid application ultrasonic is a cost effective solution. hope this is useful for you!
