A storage device is a way of storing more data
that are used in computers. A computer has many types of data storage devices.
Some of them can be categorized as the removable data storage devices and the
others the non-removable data storage devices.
The “memory” is of two types; one is the
primary memory and the other is the secondary memory.
A primary memory is the volatile memory and
the secondary non-volatile memory. The volatile memory is the kind of
memory that is erasable and the non-volatile memory is the one where in the contents
cannot be erased.
The
secondary storage devices are usually known as hard disk drives – this is the
most common type of storage device that is used in almost all the computer
systems. The other ones include the floppy disk drives, the CD ROM, and the DVD
ROM. The flash memory, the USB data card etc.
Floppy
Disk
A
floppy disk is a data storage medium that is composed of a disk thin and
flexible (floppy) magnetic that stores medium encased in a rectangular plastic
shell. Floppy disks are read and written by a floppy disk drive. Floppy disks are used to move small
spreadsheets and databases to one computer to another. Floppy disks are useful
to back up small data files.
Fixed
hard discs
A hard disk drive is the device
used to store large amounts of digital information in computers and related
equipment like iPods and games consoles such as the Xbox 360 and PS3. Hard disk
drives are used to store operating systems, software and working data. These are appropriate for any application
which needs very fast access to data for both reading and writing to.
Memory
Sticks / Pen Drives
Memory sticks have a more compact
shape, operate faster, hold much more data, have a more durable design, and
operate more reliably to their lack of moving parts. USB flash drives are
typically removable and rewritable, much smaller than the floppy disk. Storage
capacities typically range from 64 MB to 64 GB
Storage Device - Memory Card
Storage device for a
camera is used for flash memory for soiled-state electronic flash memory data
storage device used with digital cameras as well as, handheld and mobile
computers, telephones, music players, video games, consoles and many more other
electric devices. Now there are most new PCs have built-in slots for variety of
memory cards; memory sticks, CompactFlash, SD, etc. some digital gadgets
support more than one memory card to ensure compatibility, there are many types
of storage memory cards secure digital (SD), mini secure digital (MiniSD),
compact Flash (CF) type 1, Compact Flash (CF) type 2 of several other more.
