write detail note on secondary storage devices
It's input I think, not that sure, but I just know that it reads data from a disc and then views them onto the computer screen. :)
floppy disks are read/write storage devices, they are a backing store, a non-volatile long term storage which will not lose data when power is lost.Random access storage is the original term for RAM, the random access memory term was used a a marketing term and has stuck since.Another AnswerYES - floppy disk are Random Access storage devices.

There are many sorts of input devices and devices to read and write from internal storage, you need to be more specific with your question and tell us what data it is that you are tying to read.
Blu Ray disc
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.

CD-R
DVD+R is a format for optical data storage. It is similar to, but incompatible with, the older DVD-R standard. A DVD+R is a write-once optical disc with 4.7 gigabytes (GB) of storage, generally used for non-volatile data storage or video applications.
Commonly CD Read Write are used for reliable data storage as these devices offer a lot of capacity and reliability. One has to be careful with CD to ensure that these devices are protected from scratches, sunlight and dust.
A magnetic disk is a disk which stores information magnetically, and is read/written with a small magnetic head (e.g. a hard disk)An optical disk is a disk which stores information optically, usually as a series of pits and peaks, and is read/writMagnetic Storagea) Stores data in magnetic form & it doesn't use laser to read/write datab) It is affected by magnetic field.c) It has high storage capacity.d) Data accessing is high as compared to CD's and DVD's.e) Magnetic storage devices are ; Hard disk , Floppydisk, Magnetic tape etc.Optical Storagea) Stores data optically & uses laser to read/write.b) It is not affected by magnetic field.c) It has less storage than hard disk.d) Data accessing is high as compared to floppy.e) Optical storage devices are ; CD-ROM,CD-R,CD-RW, DVD etc.
