Answer:
Soft Boot
Step-by-step explanation:
Soft boot is the process in which, a computer is already on and we restart this computer to start it again.
This process is needed to conduct whenever, some software or operating system is not working properly. It is also needed when we install some new software and needs to be reboot the PC. It is also required whenever we install some new software, drivers or games on computers. The system asked us to restart or reboot the computer to operate newly installed application performs its operations in better way.
On the other hand Hard boot means that, power off the compute or controller and switch ON the computer is called hard boot. In this case, first computer is OFF and then ON, so it is not the possible answer. Rest of the two are also not suitable as Flashing boot requires when we update something on motherboard and redundant boot occurs during some failure of the system.
