2.What is an output device?

Writte down which output devices you know and post and image of each one.
3. What is the difference between RAM and ROM?
ROM (Read Only Memory) and RAM (Random Access Memory) are both vital components to any fast and productive computer
4. What is a backing storage?
In computing, memory outside the central processing unit (CPU) used to store programs and data that are not in current use. Backing storage must be nonvolatile – that is, its contents must not be lost when the power supply to the computer system is disconnected.
