TYPES OF STORAGE DEVICES EXAMPLES

2. Storage devices are referred to as storage
, storage media, or storage medium, a storage
device is any hardware device capable of
holding information. There are two storage
devices used in computers; a primary storage
device such as computer RAM and a secondary
storage device such as a computer hard drive.
The secondary storage could be a removable ,
internal, or external storage.

4. PRIMARY STORAGE
DEVICES

 There are two types of primary storage:
 Random Access Memory (RAM) – Volatile primary
storage
 Read Only Memory – Non-volatile primary storage
 Types of Read Only Memory (ROM)
 Programmable Read Only Memory (PROM)
 Erasable Programmable Read Only Memory
(EPROM)
 Electrically Erasable Programmable Read Only
Memory (EEPROM)

5. SECONDARY STORAGE DEVICES .
They are referred to as external memory and auxiliary
storage, secondary storage is a storage medium that holds
information until it is deleted or overwritten regardless if the
computer has power. For example, a floppy disk
drive and hard drive are both good examples of secondary
storage devices. As can be seen by the picture below there are
three different storage on a computer, although primary
storage is accessed much faster than secondary storage
because of the price and size limitations secondary storage is
used with today's computers to store all your programs and
your personal data.

6.  FLOPPY DRIVE:- The smallest and most portable of all the
storage devices usually holds about 1.44 MB of storage.
 A compact disc, also known as a CD, is a plastic optical disc with
a metalized surface that is used for digital audio storage. Compact
Disc (CD) can hold 740 MB.
 The DVD is an acronym for Digital Versatile Disc or Digital Video
Disc, and it refers to a type of optical disc used for storing data
and video content. The capacity of a DVD is at least seven times
greater than a compact disc and provides enough room for a full-length
feature film.

7.  External storage hardware device
developed by Data Robotics that
connects to a computer using USB,
 Fire wire, eSATA, or iSCSI and allows a
user to connect up to four or eight
SATA hard drives into it. The picture is
an example of what this device looks
like.
