CoderZ is a powerful, award-winning online platform.
Explanation:
CoderZ is a powerful, award-winning online platform through which students learn valuable STEM skills such as coding, robotics, and physical computing. CoderZ is highly flexible and designed for use in the classroom or through a wide range of remote learning environments. Computers and technology are everywhere. Studying science, technology, engineering and math gives kids valuable skills for the future and develop life-skills like computational thinking, critical thinking and problem-solving as well.
STEM and CS education focuses on how to approach complex problems, break down the challenges into small pieces and approach resolving them in a logical manner – critical skills for any career path.
'Splitting' involves dividing a single column into multiple columns.
'Validation' involves checking the data for correctness. (there slight possibility I am wrong for this one)
I hope I provided some great assistance for you, have a good day, young programer.
Answer:
24.167 micro seconds.
Explanation:
The given rotation rate = 7200 rpm = 7200 rounds per minute
Rotational latency is the average time taken for the head to reach starting of sector
.
Rotational latency (in micro seconds) = (1 / (RPM / 60)) * 0.5 * 1000
(1/(7200/60))* 0.5 * 1000 = 4.167 ms
Thus, rotational latency = 4.167 ms.
Seek time = 20 ms
The average time taken for the access head to get to the beginning of randomly selected sector will be equal to the average time to first reach the random track plus the average time taken to reach random sector
.
= 20 ms + 4.167 ms = 24.167 micro seconds.
Thus, it would take 24.167 micro seconds to get the access head to the beginning of a randomly selected sector on a randomly selected track.
