Questions- So pay attention…Please
A storage device is any computing hardware that
is used for storing, porting and
extracting data files and objects. It can hold and
store information both temporarily and
permanently, and can be internal or external to a
computer, server or any similar computing device.
A storage device may also be known as a storage
medium. (reference to art)
Internal Hard Disk
Thumb/ Flash Drive
External Hard Drive
Cloud Storage
An internal hard drive is the
primary storage device located
inside a computer system. It
usually contains preinstalled software applications,
the operating system and other
Desktops allow for multiple
internal hard drives but, laptops
can only have one.
This device has two
ports one for data that
uses a SATA cord
communication to the
motherboard, the other
port is for direct
connection to the
power supply.
This device contains vital
applications and profiles
and is susceptible to
corruption so backup is
strongly encouraged.
Usually located on
one side of the
computer case near
the bottom in the
drive bays.
Slide in or place
inside a drive bay.
A floppy disk is an older form of memory
storage, it is a flexible plastic disk coated
with magnetic material and covered by a
protective jacket used for storing data
magnetically. Developed in 1967 by IBM.
The maximum amount of data that could be
stored on a floppy disk was around 80
kilobytes of data.
They came in 3
different sizes 8”,
5.5”, and 3.5”.
One of the features
that made them
appealing was the
price and ease of
carrying them
The 8” floppy disk didn’t connect to the
motherboard directly, it rotated on a
turntable by and idler wheel, and was read
For the 5.5” and 3.5” you insert them on the
front of the computer into the floppy disk slot
that fits the corresponding disk size and they
were both read and write.
Will transform your
experience with its
random access
speeds, its
prowess and
durability and
It can hold up to
512 GB in a very
small size of 2.5”.
It was invented in 1956
by Intel.
It helped prevent
crashes and severe
data loss.
You would insert this
into your PC directly to
the motherboard.
An external hard drive
is a device located
outside of a computer
that is connected
through a USB cable or
wireless connection.
It is usually used to
store media that a user
needs to be portable,
for backups, and when
the internal drive of a
computer has reached
its maximum capacity.
The largest external
hard drive we found
online was a 25 TB .
A thumb drive/ flash
drive is relatively small
for smaller amounts of
They come in sizes
from 2GB to 128GB.
They are directly
plugged into a USB
port on the computer.
They come in many
shapes and sizes and
in all sorts of designs
to fit any person and
A BluRay is an
optical disc such as
CD and DVD but it
was developed to
for recording and
playback of HD
video and storing
large amounts of
A regular CD can
hold about 700GB
of information and
a DVD can hold
about 4.7GB, a
BluRay disc can
hold up to 25GB of
The CD and DVD can
go into the same
reader that comes with
most newer
computers, however
you need to install a
bluray disc reader in
your computer case if
you want to read and
write to bluray discs.
CD stand for
compact disc and the
R and RW are for
read and rewritable.
A CD is digital optical
storage disc data
format, it was
originally developed
to store and play
sound recordings but
was later adapted to
store data (CD-ROM)
You need a CD drive
in your computer to
both read and write
to a CD.
They can hold up to
about 700 MB of
These all go in the
same place on the
computer, just the
device used to read
them differ between
CD and BluRay.
A model of storage
where the digital data is
stored in logical pools,
spanning many servers
and locations.
The environment of the
servers is managed and
owed by a host, usually a
company that loans out a
certain amount of data or
for a period of time.
The cloud can be
accessed by any device
with an internet
An example of Cloud
storage is Google Docs.
and Drop box. Sharing is
easy due to not actually
having to give data face
to face.
Still don’t understand?
The Cloud is constantly growing and being
used by more and more people, it’s the
Portable yet weightless, simple to use
complex to understand.
Memory Card- used mostly
for video game systems,
phones or other small
devices; its portable storage
that connects on the
outside of larger systems
and inside of smaller
devices and holds small
amounts of data.
Tape Cassettemagnetically thin coated
piece of plastic wrapped
around wheels capable of
storing data, very
inexpensive but, slower
solution for backup.
Storage devices are
getting smaller and
holding more data as
time passes by.
Backup is very
important for
businesses and
personal uses, you
need a device that
can hold all your data
and be reliable at the
same time.
Everyone has there
own needs and
Q: A storage device may also be known as a
storage what?
A: Medium
Q: What is the most data storable on a external
hard drive? (that we can find)
A: 25TB
Q: What are the 3 sizes of Floppy Disks?
A: 8”,5.5” and 3.5”
