What is the difference between SSD and HDD
a)
SSD is faster than HDD when transferring data
b)
portable, higher capacity of storing data, very durable, faster performance

b)
Magnetic storage is read-write, which makes it possible to re-use the storage capacity over and over again by deleting older data
c)
1,099,511,627,776 bytes
d)
1GB to 32GB depending on the price paid
12.
What kind of technology does the optical drive use?
a)
laser beam reflect technology
b)

c)
Magnetic storage is read-write, which makes it possible to re-use the storage capacity over and over again by deleting older data
d)
1,099,511,627,776 bytes
13.
