Given a typical magnetic hard drive with five platters, answer the following:
A. How many recordings surfaces would you expect it to have?
B. How many read/write heads would it need to serve all recording surfaces?
C. How many arms holding read/write heads would it need?

Given the number of platters =5

A. Hence, the number of recording surface =10

B. number of read-write heads =10

C. Number of arms holding the read-write heads = 10

Explanation:

We know that number of recording surface = 2 *( number of platters)

= 2*5=10

And the number of read-write heads = number of recording surface= 10

Also, number of arms holding the read-write head = one for each read-write head= 10

And hence, the above answer.

a variable of array type holds a reference of object

array are commonly used in computer program to organize data so that a related set of values

array are using zero base indexing it start with 0.

all component of array have same type, two different types doesn't use in single array

if array are store 10 quantities its index value varies from 0 to 9.

it stores 1st quantity value in index value 0 and this process will same till index value 9.
