What is an Output Device? An output device is any computer
hardware equipment used to communicate with the results of data
that is processing and carried out by an information processing
system to the world. Different types of output devices are:
Speakers Headphones Screen Printer etc.
Slide 4
The Different Types of Printers. Dot Matrix: dot matrix printer
or impact matrix printer is a type of computer printer with a print
head that runs back and forth, or in an up and down motion, on the
page and prints by impact, striking an ink-soaked cloth ribbon
against the paper, much like the print mechanism on a typewriter.
Laser: A laser printer is a common type of printers that rapidly
produces high quality text and graphics on a plain paper. As with
digital photocopy and all in one, laser printers employ a dry
printing process. Inkjet: An inkjet printer is a type of computer
printer that creates a digital image by propelling droplets of ink
onto paper. Inkjet printers are the most commonly used type of
printer and range from small inexpensive consumer models to very
large professional machines that can cost up to thousands of
dollars. Plotter: A plotter is a computer printing device for
printing vector graphics. In the past, plotters were widely used in
applications such as computer-aided design, though they have
generally been replaced with wide-format conventional printers. It
is now commonplace to refer to such wide-format printers as
"plotters," even though they technically aren't.
Slide 5
Headphones. Headphones are two small speakers that are portable
and you wear it around your head. It is held around your ears and
is connected to a source which gives out sound for example a phone,
MP3s, CD Players etc. Headphones are also called headset but
headphones are more common then headsets. There is a in-ear version
of a headphone and it is called earbuds or is commonly known as
earphones. The word headset is used to describe the combination of
headphone and microphone and are used for two-way communication,
for example a phone.
Slide 6
Thin-film Transistor Monitor(TFT Monitor). TFT Monitor is also
known as a Thin-film Transistor monitor. This technology is used
for ultimate LCD display. These Monitors replaces the old CRT
Monitor as a display of choice. Many LCD monitors uses TFT
Technology know a days. The benefit of a TFT monitor is a separate,
tiny transistor for each pixel on the display. Because each
transistor is so small, the amount of charge needed to control it
is also small. This allows for very fast re-drawing of the display,
as the image is re-painted or refreshed several times per
second.
Slide 7
Cathode Ray Tube Monitor(CRT Monitor) CRT Monitor stands for
Cathode ray Monitor. When personal computers were first introduced,
nearly all came equipped with large, heavy monitors. As technology
changed and improved, more and more computers started shipping with
light-weight, and more importantly, smaller, flat screen monitors.
There are still a number of different competing technologies for
the flat screen, but all the first-generation personal computer
monitors were CRTs. In a CRT Monitor there is actually a ray
gun.
