TYPES
OF
COMPUTERS
Introduction
To
Computers
–
Technology
Applications
There are a lot of terms used to describe computers. Most of these words imply the size,
expected use or capability of the computer. While the term computer can apply to almost any
device that has a microprocessor in it, most people think of a computer as a device that
receives input from the user through a mouse or keyboard, processes it in some fashion and
displays the result on a screen. Do you know the different types of computers?
PC
Apple
iPad
Air
A
single
person
defines
the
personal
computer,
or
PC,
as
any
computer
designed
for
general
use
by
one
person.
While
a
Mac
is
a
PC,
most
people
relate
the
term
with
computers
that
run
the
Windows
operating
system.
PCs
were
first
known
as
microcomputers
because
they
were
a
complete
computer
but
built
on
a
smaller
scale
than
the
huge
systems
in
use
by
most
businesses.
Personal
computers
come
in
many
forms,
including
the
new
Apple
iPad.
DESKTOP
A
PC
that
is
not
designed
for
portability
is
a
desktop
computer.
The
expectation
with
desktop
systems
is
that
you
will
set
the
computer
up
in
a
permanent
location,
like
a
desk
or
table.
Most
desktops
offer
more
power,
storage
and
versatility
for
less
cost
than
their
portable
brethren.
LAPTOP
Also
called
notebooks,
laptops
are
portable
computers
that
mix
the
display,
keyboard,
a
pointing
device
or
trackball,
processor,
memory
and
hard
drive
all
in
a
battery-‐operated
package
slightly
larger
than
an
average
hardcover
book.

2. TABLET
COMPUTERS
Tablet
Computers
are
ultra-‐portable
computers
that
are
even
smaller
than
traditional
laptops.
Their
low
cost
means
they're
cheaper
than
almost
any
brand-‐new
laptop
you'll
find
at
retail
outlets.
However,
the
internal
components
are
less
powerful
than
those
in
regular
laptops.
Recent
improvements
to
tablet
computers
have
allowed
users
to
view
HD
video,
get
high
quality
sound,
great
photo
capabilities,
and
the
ability
to
share
information,
photos,
and
videos
with
anyone.
SMARTPHONES
Smartphones
are
handheld-‐sized
computers
that
often
use
flash
memory
instead
of
a
hard
drive
for
storage.
These
devices
usually
do
not
have
keyboards
but
rely
on
touchscreen
technology
for
user
input.
Smartphones
are
typically
smaller
than
a
paperback
novel,
very
lightweight
with
a
reasonable
battery
life.
Smartphones
have
the
same
capabilities
as
tablet
computers,
but
also
allow
users
to
text
or
make
phone
calls.
WORKSTATION
Another
type
of
computer
is
a
workstation.
A
workstation
is
simply
a
desktop
computer
that
has
a
more
powerful
processor,
additional
memory
and
enhanced
capabilities
for
performing
a
special
group
of
task,
such
as
3D
Graphics
or
game
development.
They
may
even
use
multiple
screens
to
enhance
their
viewing.
SERVER
A
computer
that
has
been
optimized
to
provide
services
to
other
computers
over
a
network.
Servers
usually
have
powerful
processors,
lots
of
memory
and
large
hard
drives.
Servers
allow
many
computers
to
share
a
printer
or
other
devices
without
the
cost
of
having
to
buy
one
for
every
computer.
Servers
also
allow
users
to
share
information
and
files
with
each
other.
The
computers
in
this
lab
are
part
of
a
network.
MAINFRAME
In
the
early
days
of
computing,
mainframes
were
huge
computers
that
could
fill
an
entire
room
or
even
a
whole
floor!
As
the
size
of
computers
has
diminished
while
the
power
has
increased,
the
term
mainframe
has
fallen
out
of
use
in
favor
of
enterprise
server.
You'll
still
hear
the
term
used,
particularly
in
large
companies
to
describe
the
huge
machines
processing
millions
of
transactions
every
day.
Mainframes
store
vast
amounts
of
information.

3. SUPERCOMPUTER
This
type
of
computer
usually
costs
hundreds
of
thousands
or
even
millions
of
dollars.
Although
some
supercomputers
are
single
computer
systems,
most
are
composed
of
multiple
high
performance
computers
working
in
parallel
as
a
single
system.
Supercomputers
are
the
fastest,
most
powerful,
most
expensive
computers
made
today.
The
best-‐known
supercomputers
are
built
by
Cray
Supercomputers.
Many
of
today’s
great
movies
use
supercomputers
for
their
CGI.
They
can
perform
over
a
trillion
calculations
per
second.
WEARABLE
COMPUTERS
The
latest
trend
in
computing
is
wearable
computers.
Essentially,
common
computer
applications
(e-‐mail,
database,
multimedia,
calendar/scheduler)
are
integrated
into
watches,
cell
phones,
visors
and
even
clothing.
Users
can
use
these
devices
for
health
and
fitness,
navigation,
social
networking,
and
gaming.
Google
can
now
augment
a
person’s
vision
through
special
computer
glasses.
The
glasses
can
stream
information
to
the
lenses
and
allow
the
wearer
to
send
and
receive
messages
through
voice
commands.
There
is
also
a
built-‐in
camera
to
record
video
and
take
pictures.
