Answer» hi friends.....plz tell me the procedure and answers for 2 questions..please...
a) A magnetic disk has 32 sectors per track, 128 tracks per surface, and 19 surfaces. Each sector has 512 bytes. CALCULATE the total capacity of the disk.
b) A magnetic disk has 64 tracks per surface, and there are 12 storage surfaces out of which 10 are recordable. The capacity of the disk is 200 MB and the disk rotates at 7200 rpm. The average seek time is 50 milliseconds. Calculate the data transfer rate of the disk. SOUNDS LIKE homework, which most people here won't just give you the answers to. Put a LITTLE EFFORT in...
...or at least try Google...
