Have you
ever heard computer? Have you ever seen computer? Have you ever touched
computer? Have you ever operated computer? The answer must be yes if you live
in this age and spend your life using technologyNowadays, we all almost use
computer to finish many things easily. We could also simply say what computer
is and the answers could be different based on the usage of computer.
However,
let us start and go back to the first time this device was born. In the early
age of computer, it simply mean “to compute” because the device just only used
to operate a counting operational and the device looked so monstrous with huge
parts in it. We cannot simply use and move it because it at that time because
the weight was so heavy.
The
early electronic computers consisted of thousands vacuum tubes that was used to
converting a portion of the telephone exchange network into an electronic data
processing system. Nevertheless, today, all of the modern computers change into
integrated circuits or IC. The change of the computer parts also happen during
the period of computer age and the revolution of technology led the change of
computer to the most useful device human need.
Computer’s
hardware commonly grouped into three partitions that supported each other. Let
us started with the first one, it is input partition. Keyboard, mouse, microphone,
scanner, and drawing tablet are the input device. Keyboard consists of letters
button that commonly called qwerty keyboard. The function is an interface to
type the letter and number. Mouse seems like a real “mouse” consisted left and
side button with a roller in the center. The function of mouse is to click and
scroll the menus in the software. We can use microphone to input sound or our
voice when we record a song. the document or any printed object on the paper
can be saved in the computer by using scanner. It looks like a copy machine but
in smaller. At the last, drawing tablet is an interface for drawing or
designing where mouse cannot give a smooth and better handling on it.
Then,
the second one is process partition or people just simply say hardware. There
are some important parts of process partition. The first is processor; it is
the central of processing unit or the brain of a computer. The latest processor
we use the best performance we get. Then, there is a storage media called hard
disk. The space in the hard disk called Giga Byte or GB and today we can buy
the bigger one, which is Tera Byte or TB. Next, it is RAM or Random Access
Memory. It is the temporary memory used to process the application. The space
in the hard disk called Giga Byte or GB. At the last, there are Motherboard,
Driver, and Graphic card. The Graphic card is also important to improve the
quality of display.
At the
last, the third one is output partition. It is a common thing we could find in
a computer like monitor, speaker, and printer. Today, the most famous monitor
is made by using LED and LCD technology where have better qualities than tube
monitor. We could also print our picture by using printer. Well, today we could
just simply choose computer by its specification that fits to our need like
office, graphic design, music, etc.
