Answer:
Trap is a software interrupt that occurs when there is a system call, while hardware interrupt occurs when a hardware component needs urgent attention.
Explanation:
Interrupt is an input signal that disrupt the activities of a computer system, giving immediate attention to a hardware or software request.
In trap interrupt, the system activities are stop for a routine kernel mode operation, since it has a higher priority than the user mode. At the end of the interrupt, it switches control to the user mode.
The hardware interrupt is a signal from hardware devices like the input/output devices, storage and even peripheral devices that draws an immediate attention of the processor, stopping and saving other activities and executing the event with an interrupt handler.
Answer:
shutdown -h +15 It is time for a shutdown!
Explanation:
In a work environment where there is an admin and users connected to the server when the admin wants to Give a 15-minute delay to allow users enough time to save their work data and logout from the system. the command above shuts down after 15 minutes delay and notifies the user with "It is time to shut down!".
user_str1 = str ( input ("Please enter a phrase: "))
user_str2 = str ( input("Please enter a second phrase: "))
def strcmp (word):
user_in1 = int (len(user_str1))
user_in2 = int (len(user_str2))
if user_in1 > user_in2:
return "Your first phrase is longer"
elif user_in1 < user_in2:
return "Your second phrase is longer"
else:
return "Your phrases are of equal length"
