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:
having a capital and lower case letters and a special characters and numbers.
Explanation:
it should be hard but easy enough to remember and no one will know
Answer:
shortNames = ['Gus', 'Bob','Zoe']
Explanation:
In this assignment, your knowledge of list is been tested. A list is data structure type in python that can hold different elements (items) of different type. The general syntax of a list is
listName = [item1, "item2", item3]
listName refers to the name of the list variable, this is followed by a pair of square brackets, inside the square brackets we have items separated by commas. This is a declaration and initialization of a list with some elements.
The complete python code snippet for this assignment is given below:
<em>shortNames = ['Gus', 'Bob','Zoe']</em>
<em>print(shortNames[0])</em>
<em>print(shortNames[1])</em>
<em>print(shortNames[2])</em>
Answer:
Time taken to travel from one track to the next = 0.08ms
Initial track= 15 0
4 (15-4)*(0.08)= 0.88
40 (40-4)*(0.08)= 2.88
35 (40-35)*(0.08)= 0.4
11 (35-11)*(0.08)= 1.92
14 (14-11)*(0.08)= 0.24
7 (14-7)*(0.08)= 0.56
----------------------------------------------
Total seek time=0.88+2.88+0.4+1.92+0.24+0.56=6.88ms
Explanation:
We caculate the seek time for each request, and then add them together to find the total seek time. The final track number for the current request becomes the current track of next request, and this process is repeated till the last request is processed.
