As soon as the machine is switched off, data is erased. RAM is volatile. Volatile means that the data stored in memory is lost when we switch off the computer or if there is a power failure. There are different types of RAM available. Some of them are described below. The term dynamic indicates that the memory must be constantly refreshed or it loses its contents.

This type of memory is more economical. The term static is derived from the fact that it does not need to be refreshed like DRAM. This type of memory is non-volatile. The information is stored permanently in such memories during manufacture.
A ROM, stores such instructions that are required to start a computer. This operation is referred to as bootstrap. The different types of ROM are given below.
The MROM cannot be programmed by the user. EPROM is erased by exposing it to ultra-violet light for a duration of up to 40 minutes.
It can be erased and reprogrammed about ten thousand times. Both erasing and programming take about 4 to 10 milliseconds. Secondary Storage External Storage Devices Floppy diskettes, hard disk, tapes and optical disks come under the category of external storage devices or ancillary storage devices.
These devices are very sensitive to environmental conditions humidity and temperature as well as to external magnetic fields and need to be stored carefully. Information on a floppy disk is recorded in the magnetized states of particles of iron oxides evenly placed upon concentric circles known as tracks.
It contains a stack of metal platters, each coated with iron oxide, that spin on a spindle and the entire unit is encased in a sealed chamber. C Magnetic Tape This is plastic tape, usually made of Mylar that is coated with iron oxide, thereby enabling the introduction writing ; retention memory and reading of magnetically recorded information. The best use of tape storage is for data that you do not use very often.
If a peripheral device is disconnected, the computer will still be able to work; only functions performed by this peripheral device will not be available. Davinder Singh Minhas.
