Detailed Solution
Download Solution PDFThe correct answer is option 4.
Key Points
The capacity of a track is=bytes / sector x sector / track= 512x50=25k
Since one track of data can be transferred per revolution,
Data transfer rate = tracksize÷rotational delay
if the disk platters rotate at 5400rpm, the time required for one complete rotation will be, 1/5400 x60= 0.011 seconds
Rotational delay=0.011
Data transfer rate=2250K÷ 0.011= 2,250 KBytes/second
∴ Hence the correct answer is 2,250 KBytes/second.
