If a disk drive has 8 surfaces and there are 1024 tracks per surface with 256 sectors per track and 512 bytes/sector. what is the capacity of the drive?

Capacity of the drive equals 1073741824 bytes.

Explanation:

Since it is given that there are 8 surfaces with 1024 tracks per surface thus the number of tracks in 8 surfaces equals

Now since it is given that there are 256 sectors per track thus the number of sectors in 8192 tracks equals

Now since it is given that there are 512 bytes per sector thus the number of bytes in 2097152 sectors are

Thus the number of bytes in the memory equals 1073741824 bytes.

hi,

a perfect network would be right as you search something it would work in a snap, super protected, no hackers, would have maintenance every week, everyone one would share anything and everything as long as its safe, no viruses or over 18 stuff.communication would be like hangouts, and a network administrators would check what is happening and check if everything is safe.

hope this !

loool i m also trying to figure that out.seems like u should have genius ranking
