Output Devices
Introduction
Monitors
After you enter all the data into the computer and the CPU has had time to
process the information, it exits the computer through an output device.
Monitors, plotters, printers, and film recorders are output devices. They
provide the SYSOP with an image or hard copy data.
Monitors provide visual feedback of work in progress. The three types of
monitors are the analog monitor which is similar to a television set but
provides only a video display, the digital monitor which processes data as a
numeric value and provides only a textural display, and the multi
synchronous monitor which provides both analog and digital information.
Multi synchro-
nous monitors
Multi synchronous monitors are capable of processing both analog and digital
information. They work on any computer system displaying text and
graphics with superb resolution and can vary resolution at the SYSOP
discretion. Resolution is the number of pixels per inch and is referred to as
dots per inch (DPI). The dpi in height and dpi in width define the display of
the monitor. A 17- or 20-inch monitor rated at 640 by 480 dpi or higher is a
good monitor for general-purpose work. This is the type of monitor you will
most likely be using.
Plotters
Plotters are output devices used for large linear drawings. The drawing or
design is conveyed to the paper surface by plotting a series of points and
connecting them with lines. Plotters are most often used for drafting or map
making.
