INTRODUCTION
Modern computers have dedicated RAM for running
programs, and large volume storage to record program
outputs and to store data when not in use. Large volume
storage trades access speed for capacity; and it comes in
three broad categories; internal to the computer, external
to the computer and storage that is accessed via a
network.

3. Internal storage is a device housed inside the computer. It comes in
two broad types, as of 2014; spinning disk hard drives and solid state
hard drives. Spinning disk drives have platters of magnetic material
that get written and rewritten by a drive head. Solid state disks use
flash memory to store data. Solid state disk drives are much faster
than spinning platters and can fit unusual case shapes, like the
MacBook Air or Ultrabook for example. Solid state drives are much
more expensive for a given capacity than a conventional spinning
disk drive.

EXTERNAL STORAGE
External storage devices include removable media like
optical disks and SD Cards and USB-connected flash drives
(called “thumb drives” because of their size) and externally
connected hard drives. External storage is used to back up
computer data, move files between a network, and make
copies of something for other users. As of mid-2014, optical
disks are on the way out in consumer devices, external hard
drives are used for backing up systems, and thumb drives
are used for most conventional file transfers.

5. NETWORKED
STORAGE
Networked storage devices included shared file servers,
networked accessible storage (NAS) devices, and cloud
services. All of these take the idea of an external hard
drive and change the connection method from USB to full
network connectivity. You add file servers to your local
domain and have total control over who accesses which
files on your server. You can plug a NAS device to your
router, and every computer on your local network can store
files on it for a more informal file sharing method. You can
also use services like DropBox, Box, and SkyDive to put
files up on another vendor’s servers and access them
through the Internet.
