Answer:

import random

def name_change( name: list ) -> list :

   choice = random.choice( name )

   choice_index = name.index( choice )

   name.pop( choice_index )

   return name

Explanation:

The python source code above makes use of the random package to select an item from a list in the function "name_change" and the index of that item is gotten fro the list and popped from the list "name", then the name is returned.

To call the function, assign it to a variable and add a list ( must be a list ) as its argument then print the result.

Consider a single-platter disk with the following parameters: rotation speed: 7200 rpm; number of tracks on one side ofplatter:
horsena [70]

Answer:

Given Data:

Rotation Speed = 7200 rpm

No. of tracks on one side of platter = 30000

No. of sectors per track = 600

Seek time for every 100 track traversed = 1 ms

To find:

Average Seek Time.

Average Rotational Latency.

Transfer time for a sector.

Total Average time to satisfy a request.

Explanation:

a) As given, the disk head starts at track 0. At this point the seek time is 0.

Seek time is time to traverse from 0 to 29999 tracks (it makes 30000)

Average Seek Time is the time taken by the head to move from one track to another/2

29999 / 2 = 14999.5 ms

As the seek time is one ms for every hundred tracks traversed.  So the seek time for 29,999 tracks traversed is

14999.5 / 100 = 149.995 ms

b) The rotations per minute are 7200

1 min = 60 sec

7200 / 60 = 120 rotations / sec

Rotational delay is the inverses of this. So

1 / 120 = 0.00833 sec

          = 0.00833 * 100

          = 0.833 ms

So there is  1 rotation is at every 0.833 ms

Average Rotational latency is one half the amount of time taken by disk to make one revolution or complete 1 rotation.

So average rotational latency is: 1 / 2r

8.333 / 2 = 4.165 ms

c) No. of sectors per track = 600

Time for one disk rotation = 0.833 ms

So transfer time for a sector is: one disk revolution time / number of sectors

8.333 / 600 = 0.01388 ms = 13.88 μs

d)  Total average time to satisfy a request is calculated as :

Average seek time + Average rotational latency + Transfer time for a sector

= 149.99 ms + 4.165 ms + 0.01388 ms

= 154.168 ms

An administrator has initiated the process of deploying changes from a sandbox to the production environment using the Force IDE
Pani-rosa [81]

Option A because the environment should be selected for which the changes are to be applied. In a time Force IDE has many project environments for example maybe a java project and C++ project would be there on sandbox, so the environment selection is important.

Option B because the related changed sets should be specified so that other developers that have access to the project can see the changes being made.

Option D The data fields that are needed to be deployed should also be provided so that the updated version can be seen by other developers.

Rejected Options :

Option C user name and password has nothing to do with the production environment because if the user has it only then it can come and make changes.

You are describing the boot process to a friend and get to the step where the device loads the operating files into RAM, includi
EastWind [94]

I would say, "not those kinds of kernels, when I say kernel, I mean the core of your computers operating system. It controls all of the system components and tell specific parts of the computer to do certain things." or in more compact terms, "think of the kernel as the brain of the computer, telling each system component what to do."
