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.
Answer:
Start the algorithm and check the weight of the ship. Load the crystalline to the ship. Check to see if the ship weighs ship weight + k pound crystalline, if less, add more crystalline. If excess, remove the excess crystalline, but if the weight meets the condition, then take off with the loaded ship to planet sigma.
Explanation:
The algorithm continuously checks the weight of the ship on loading with the calculated sum of the ship and k pound crystalline weight. The ship is able to load the correct maximum amount of crystalline to the planet sigma.
Answer: The QA/Testing process consist of the following:
1. Requirement specification
2. Reviewing the code.
3. Unit testing
4. Integration test
5. Performance testing
Explanation:
We start of by the requirement specification try to gather all the information accurately. Then begins the coding process where there is review of the code so that they perform their desired purpose. After modules are completed we perform unit testing of the different modules individually and also do the integration testing once all the modules are completed. At the end we perform the performance testing to take a note on their desired output and other quality parameters.
