Unit 4: Secondary Storage Devices

• Output devices is used display the result of computer. Notes

• Digitizer consists of a digitizing tablet (also know as graphics tablet) associated with
a stylus.

• A potters is special type of output device that use in computer.
• Lager printer are non impact printer, they are very quiet in operation. Being of non-
impact type, they can not be used to produce multiple copies of a document in a single
printing.

4.6 Keywords
Terminal: A monitor is associated usually with a keyboard and together they form a Video
Display Terminal (VDT). A VDT (often referred to as just terminal) is the most popular
input/output (I/O) device used with today’s computers.
Hot-Spot of graphics: The graphics cursor, irrespective of its size and shape, has a pixel-size
point that is considered the point of reference to decide where the cursor is positioned on
the screen. This point is called hot-spot of the graphics cursor.

Flush memory: Storage technology Recall that flash is non-volatile, Electrically Erasable
Programmable Read Only Memory (EEPROM) chip.

Plotter: A special type of output device, called plotters, is used for this purpose. Plotters are
an ideal output device for architects, engineers, city planners, and others who need to
routinely generate high-precision, hard-copy, graphic output of widely varying sizes.
LCD: LCD stands for Liquid Crystal Display, referring to the technology behind these
popular flat panel monitors.
Digitizer: A digitizer is an input device used for converting (digitizing) pictures, maps, and
rawings into digital form forstorage in computers. For example, the x and y coordinates of
points in a drawing may be stored in digital form.
