What is a optical microscope?
An optical microscope is what is commonly known as compound microscope.
What are optical storage devices are most commonly known as?
An optical storage device is an electro-mechanical unit that can save and retrieve (write and read) information on a special disc medium using a laser light. Optical drives are designed to work with several types of media: CDs ("compact disc"), DVDs (digital versatile disc" or "digital video disc") and Blu-ray discs.

Is a flexible disk input or output?
A flexible disk is more usually known as a floppy disc and they were a feature of all early personal computers as larger computers as well. They have such small capacities that they have been replaced by hard disks, optical disks and USB based storage. The discs were considered to be storage rather than input or output. However, the disc drive that handled the disc can be thought of as an input and an output device.

What is optical energy?
Optical Energy, better known as Optical Power, is the converging strength of a lens. As an example a lens with a high Optical Power will have a wider range of view but less focal distance. A lens with low Optical Power will have a longer focal distance but less range of view.
What is the game where you move rings on to a different post without putting larger disks on to smaller disks?

What uses magnetic particles to store items on a disks surface?
Magnetic Disks, otherwise known as 'Floppy disks'. The last generation of these disks were 3 1/2" and used a ridgid plastic case, to contain the magnetic disk within. Not very floppy. The early versions were 7" and 5" and were contained in soft plastic outer sleeves. These were actually floppy.
What are 3.25 inch or 5.25 inch diskettes?
