§ Distributed processing separates the data processing onto different servers rather than on one dedicated host computer
a) Cathode-Ray Tube
§ Most common type of desktop monitor.
§ Uses similar technology as standard TV screens
§ Advantage is they are relatively inexpensive and have a high quality image display.
§ Disadvantage is they take up a lot of room
b) Flat-Panel Monitor
§ The advantage is they take up less room, and are frequently used on laptop computers. Now becoming popular for desktops as well since they have dropped in price
§ Two basic types are:
§ Passive matrix (dual scan monitors): lower power, but poorer clarity
§ Active matrix (TFT: Thin Film Transistor): costs more, uses more power, but produces a much better image.
c) Other (Specialty) Monitors
§ E-books (aka e-book readers) are PDA sized devices that display text and graphics. These have not had a lot of commercial success, yet it is possible to download e-books onto computers.
§ Data projectors: capable of projecting the output onto a screen for a large audience
§ High Definition TeleVision (HDTV): a merger of microcomputers and television (PC/TV) offers much clearer and more detailed wide screen pictures than a standard TV (but currently at more cost). Since images are digital, they can be stored and edited.
