Types of Computers - A brief introduction
When looking at types of computers you are going to be amazed at
the various technologies offered on on the market. Computers come in all different sizes, shapes, and with varying
In the high end you will find what are called supercomputers.
They are massive computers with thousands of connected computer
microprocessors and then some. They perform unbelievable
calculation feats by tackling the most complex calculations.
On the other side you will find super tiny computers that are in
everything from automobiles, to TV's, to even some
refrigerators. Of course the use of tiny microprocessors
doesn't end there either. Take for example a device called
a Cochlear implant, it helps the hearing impaired and even
relies on a tiny microprocessor.
Now that you have a very basic understanding of types of
computers, lets move onto the personal computer, otherwise known
simply as the PC. We are going to overview various types
of personal computers including: desktops, laptops, handhelds
and Tablet PC's.
computers in general are designed primarily for use at a desk.
Because they are stationary during their life desktop computers
are typically very powerful compared to other types of computers
such as a laptop.
The typical desktop computer is loaded with powerful components
because size isn't too much of an issue. In contrast a laptop
requires components to have been shrunk tremendously for
functionality, and in the computer world bigger is often better
when it comes to sheer speed.
Desktop computers in the most general terms are made up of
separate components including the system unit, monitor,
keyboard, mouse, and speakers. The system unit is the most
important piece for it contains the guts and brains of the
System units are normally a rectangle box/case that sits on or
underneath a desk. Other components, such as the monitor, mouse,
and keyboard come in various shapes and sizes but look fairly
general across the board. All connect in some fashion into
the system unit completing the desktop computer.
Laptop computers are lightweight mobile PCs
that contain thin screens and tiny frames.
They are also often called notebook computers too because of their small
When looking at the types of computers laptops can pretty much
do what a desktop PC can, though because of its smaller nature
it isn't going to be as powerful as a full fledged desktop and
thus will have some limitations.
Despite a minor limitation in the processing power department,
which I should mention only really hinders the crazy power user,
a laptop computer effortlessly can operate on batteries allowing
you to be able to literally take one
anywhere. Take it to the local StarBucks, your neighbors,
on vacation, or even to the beach.
On a physical level a laptop unlike a desktop combines the
internal hardware components, screen, and
keyboard in a single case. Fold the screen down over the
keyboard when not in use, drop it in your laptop bag, and your
off to your favorite destination. Try that with a desktop,
we dare you!
The smallest types of computers are handhelds. You may also hear
someone call one a personal digital assistant (PDA), or pocket
Handheld computer systems are battery powered and small enough
to carry pretty much anywhere you please.
Pocket computers because of their absolute tiny frame are not
nearly as powerful as desktop or laptop computers, but they are
powerful enough in their own right to tackle plenty of computing
They are great for the business man or even the busy housewife
who likes to stay highly organized. PDA's are awesome for
storing addresses, your friends, family, and co workers phone
numbers, scheduling appointments, and even playing the
occasional bathroom break game.
Some handhelds including the IPhone have more advanced
capabilities including making telephone calls, accessing the
Internet, and more. Some handhelds have mini thumb touch
keyboards, and others handhelds have touch screens that you use
with your finger or a pen like tool called a stylus.
Tablet PCs are unique types of computers. Like a laptop
they are mobile computers which allow you the freedom to take
them with you out and about.
Like some handhelds the typical Tablet PC functions using a
touch screen. On the left you will see a common tablet PC model.
The most unique feature with a tablet PC's is that you have the
ability to write on one electronically using a special pen
called a tablet pen. For example you can draw pictures,
control the cursor, or take notes electronically on the screen
using the tablet pen.
One cool feature definitely worth mentioning about tablet PC's
are that they include software which has the ability to convert
your handwriting into typed text. Sometimes it works
great, other times it is iffy, though in a short period of time
all but the sloppiest writers will have adjusted their writing
style a bit to where the handwriting text recognition software
