I heard our teacher say “output” in

class yesterday.

What do you think that means?

I don’t know, let’s ask. Hey

Mac – What’s

Output??

That’s an easy one. Output is anything

that comes out of a

computer.

It could be a display on the computer

screen, hardcopy on printed pages, or even the audio

playback of music you composed on the computer. Let

me show you.

The first type of output is Visual

Output

ZvBox Broadcasts any Internet TV or

Computer Content to your HDTVs

Just like a television set (an older one, anyway) the CRT monitor contains a large

cathode ray tube that uses an electron beam of varying strength to “paint” a

picture onto the color phosphorescent dots on the inside of the screen.

The LCD consists of several thin layers that polarize the light passing

through them. A video projector

takes a video signal and

projects the corresponding

image on a projection screen

using a lens system.

WOW! Video Output is really

cool!

Hey Mac, what about audio. Is that an output

too?

It sure is! There are a

ton of different Audio

Output devices.

One type is voice recorders or TTS devices. These turn text into speech.

And of course you know about speakers. Those

are audio devices too, since they output sound

from the computer to your

ears!

Another type of output is Hard Copy Output.

The most common form being printers.

So I use output all the time

when I use my ink jet printer and I didn’t

even know it!

The most common type of printer for home systems is the

color ink jet printer. These printers form the image on the page by spraying tiny droplets

of ink from the print head.

A laser printer produces good quality images by the

same technology that photocopiers use. A drum coated with photosensitive

material is charged, then an image is written onto it by a

laser

Hey Kids. I bet you didn’t think of

your IPod as output either but it is. It’s just one type of Storage

Output

I get it! It’s because we “output” our

music onto it!

External hard drives and flash drives are other types of storage

output.

Thanks for telling us all

about output Mac!

It was so much fun!!

No problem

kids. Happy

Outputing!!
