COMPUTER TECHNOLOGY
Computer Technology is the study of the hardware
and software that are the foundations of modern
computer systems. Computersare now a fundamental
part of everyday lives, controlling everything
from toasters to nuclear power stations.

INTRODUCTION OF COMPUTER TECHNOLOGY
Nowadays, Computers has penetrated every facet of
our life. From leisure to social to conducting
business, computers are increasingly more
indispensable. In order to satisfy the increasing
demands of savvier computer users, a wide variety
of computers are developed to meet this need.
Some examples of computers will be the mainframe,
supercomputers, microcomputers, personal
computers and others. In this report we will
discuss more on the personal computers which is
the most common computer. Computers technology is
evolving every single day in order to satisfy the
high demands of computers user. For example the
personal computer has been evolving from the
desktop computers to laptops, netbook, tablets
and smart phones.

HISTORY OF COMPUTERS
The great creation of computer technology begins
with Charles Babbage, who developed the
Difference Engine, which is considered being the
first automatic computing system that was capable
to compute several sets of numbers with
equations. Unfortunately, he was unable to
complete a totally functional machine because he
has insufficient funds. The London Science Museum
has completed the Difference Engine 2 at the
bicentennial year of Babbage's birth. In year
2000, the printing technology had been added to
the Engine as well.

Defining Laptop
Some main components that are commonly used to
define a laptop are ? Hard Drive ? GPU (graphic
processing unit/Graphic card) ? Processor ? Operat
ing System ? Battery ? RAM

Hard Drive
The hard disk drive (HDD) is the primary storage
on the laptop. Unlike RAM, HDD keeps data while
power is running in low profile, Saved remains in
the HDD until you remove it manually. HDD space
was limited during the early days that users went
to great lengths to conserve some space. Modern
HDDs are so capacious and affordable that most
people now regard disk space as free. The
disadvantage is that the modern HDDs can be
troublesome to install and configure.

Processor
The processor in the laptop motherboard provides
the technology to determine the memory and other
components the computer can access. Of course,
the more number of processors, the performance of
the laptop will be faster and smoother. The
performance of the processor depends on the end
user?s choice. Basic processor like Intel Core 2,
Core i3 are for user that require basic uses like
email, writing reports or any other office work.
High performance or overclocking processors are
for users who are into extreme graphical programs
like Adobe After Effects (CS5) or game developing
software that requires faster speed processing..

GPU
The graphical processing unit is a circuit board
that is connected to the laptop?s motherboard
where it manipulates and enhances the image frame
buffer rate. The higher bit rate of the GPU, the
better and smoother, the graphical performance
is. GPU also comes in various memory sizes from 1
Gigabyte to 4 Gigabyte. This is mostly
recommended to gamers that wanted to enjoy their
games on the go.

Operating System
A laptop with an out-dated operating system will
not be useful. So it is best to have a laptop
with an updated operating system. Some common
operating systems are Windows 7 and Windows XP.
However, there is an operating system, Windows 8
which was recently released and brought a lot of
inconvenience to the public as it is not
compatible to some software. Windows 8 has a
touch screen compatibility for mobile devices and
new model laptop which has touch screen
functions.

Battery
The battery component of a laptop varies on the
length of time the user is working on his laptop.
If the user works longer hours it will be better
to have a battery with longer life so there is no
need to find power plug for charging. That is why
consumer purchases laptop with more cells which
is able to last for about 4-5 hours.
