The desktop bought computing right inside
our home. In early days of computing, computers used to be as big as a room.
Desktops miniaturized the mainframe computers enough to be placed on a desk
thus the name desktop computers.
A desktop computer is a combination of
components that work together to gather input, compute the data and provide and
output. The keyboard and mouse is your input device, you use it input commands
and instructions you wish to run on the computer. The keyboard and mouse are
connected to the computer tower. The computer tower houses the brain and heart
of the computer. Within the computer tower you will find the motherboard that
has the processor mounted on it. The processor is the brain of your computer and
does all the calculations. Other than the processor the motherboard has
connectors which connect to the hard drive which stores data and the optical
drive which reads and writes compact discs. It has various other connectors and
is powered by the switch mode power supply.
The processor analyses and runs the
commands and an instruction provided as an input and provides an output which
is a result. The output is displayed to the user with the help of your computer
screen which is connected to the computer tower. All of these components
require a lot of space which is what is scarce these days.
Enter the laptop, a mobile computer that
folds right down the middle and can be carried anywhere you go. The laptop took
computers off the desk and miniaturized them enough to be placed on your lap
while using them. Hence they earned the name laptop or netbook as they fold
like a netbook does.
A laptop has all the components that your
desktop does except it has a track pad instead of a mouse. A laptop can do
everything that you can do with a desktop and more. It is fascinating how
something so small can still match the performance of desktops that we all used
for our computing in the last decade.
It has a flat screen for output and
keyboard, track pad for input. So where did the computer tower go? In case of
the laptop it was made compact. You still have your hard drive, optical drive,
motherboard with all its connections and the processor. They just have been
arranged in a way so as to rest right beneath the keyboard. Drastically
reducing the space required. Also the laptop has a built in battery which means
you are not dependent on the wall socket for powering the computer all the
time. Once charged you can take the laptop and use it anywhere without any
chords attached.
The laptop has gone on to replace desktop
in almost all fields where computers are used. To know more visit our reviews website.
