● Lightweight
● No moving parts, therefore robust
Is ROM volatile or non-volatile?
Non-Volatile
Which form of storage device uses
silicon semiconductors to store
information?
Flash
Give three disadvantages of CDs
● They are easily damaged by scratches
● They have relatively low capacities
● They have relatively slow transfer speeds
