Answer: b)because near-critical paths could become critical paths with small delays in these activities
Explanation: Program evaluation and review technique(PERT) technique is used for management of the project .The organizing, maintenance,coordination of any task is done by this chart. The non-critical activities need to be observed carefully because they may create near-critical methods which can lead to complexity.
Other options are incorrect because not all activities are equally rather monitoring is done to avoid errors and slack can occur at any path . Small delays can be caused but not complete project can get delayed and there can be risk of complexity rather than being uncompleted.Thus, the correct option is option(b).
The
answer is FALSE because the
interior of commercial Hard disk drive is with stack of magnetic disks
(platters) containing the user’s data and a rotating arm supporting the magnetic
heads. The rotating arm is moved by the torque generated by a voice coil motor
(VCM) mounted at one end of the arm. Data read/write operations rely on the capability of the
governing unit of the HDD to maintain the magnetic read/write heads as close as
possible to center of the desired track. Typically, reliability of data reading
and writing is guaranteed when the head is kept within 5% of the track pitch
from the track center. This means that the accuracy required for the head positioning
is in the range of a few tens of nanometers.
Answer:
// here is code in C++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
double num;
// read discriminant
cin>>num;
// calculate square of the input
double result=num*num;
// print the square number
cout<<result<<endl;
return 0;
}
Explanation:
Declare a variable "num".Read the value of "num" from keybord.Then calculate square of the input number.Print the square of input number.
Output:
5
25
