Chapter 6 - Output
Impact: forms visuals on a document by actually striking a mechanism against the ink ribbon that hits the paper.
Can be very noisy
Produces near letter quality (NLQ) output, which is slightly less than what is acceptable for business letters.
Nonimpact: forms visuals, but never actually touches the paper.
They either spray ink, or use heat and pressure.
Most printers are nonimpact in present day.
Audio output device: part of a computer that produces music and other sounds.
Speakers and headsets are most common.
Speakers have two parts to them
Woofer: enhances bass
Tweeter: enhances higher noises
Headsets allow for audio where a speaker is not practical, such as in a lab, or in a crowded space.
Voice Output: when you hear a person’s voice or when the computer verbally communicates to the user.
Data projectors: a device that uses the image from the computer screen and projects it onto a larger screen for an audience.
There are two types.
LCD: uses liquid crystal display technology.
DLP: digital light projector. It uses tiny mirrors to reflect images clearly, even in a well lit room.
