OUTPUT

OUTPUT

1. receive data and transform the data into a form that comp . can understand

   • output devices
     • 1. monitors
       • 1.1 features
         • #1 resolution ( measured by pixels ) > resolution > clear image
         • #2 dot pitch ( distance between pixels , <distance , > clearer image)
         • #3 contrast ratio ( light intenstity of brightness white : dark intensity of darkest dark )
         • #4 size ( measure by diagonal length)
         • #5 aspect ratio ( indicates proportional between width : height)
       • 1.2 FLAT BED MONITORS
         • use LCD (liquid crystal display)(older monitor and typically less expensive)
         • use LED (Light Emitting Diode) ( more advance)
       • 1.3 EBOOK READERS
         • e-book ( traditional mobile device that have printed book in electronical format )
         • e- readers ( dedicate to mobile device that storing + display e- books + other media )
         • e- ink ( produce an image that reflect light like ordinary paper . making easy to read because exactly like the article )
       • 1.4 OTHER MONITORS
         • 1. Digital or Interactive Whiteboards ( specialised device that used a large display sceen + connected to comp / projector )
         • 2. Cathode Ray Tube ( just like HDTV but more harmful and hazard because use approxiamately lead+ numeruous hazard things )
         • 3. HDTV ( clearer image . and the output is in digital state so user can easily freeze certain part of video and edit it )
     • 2. PRINTERS
       • 2,1 features ( SAME LIKE MONITORS )
         • #1 RESOLUTION ( same monitors)
         • #2 SPEED ( measured by the amount of output produced in 1 min. )
         • #3 MEMORY ( the memory stored in the prnter to display the queuing paper)
         • #4 COLOR (usually use black )
         • #5 DUPLEX PRINTING ( print on both side automatically)
       • 2.2 TYPE OF PRINTERS
         • 1. Laser Printer ( use HIGH laser light beam to produce HIGH quality of images )
         • 2. Therma Priter ( use heat to produce informatio on sensitive-heat paper)
         • 3. Inkjet printer ( mostly sed . affordabe . the most expensive part is the ink catridge )
         • 4. 3D printer ( connect to data that consits f 3D apps. and built by putting papers layer by layer in the printer
         • 5. Cloud Printer ( connect to a program that use internet and obtan rinting services)
         • 6. plotters ( to produce a wide and large image on a large paper such as map )
     • 3. AUDIO OUTPUT DEVICES
       • convert audio information to a form that human can understanding
     • 4. INPUT AND OUTPUT COMBINATION
       • 1. multifunctioning device ( printers(output) that have a scanner(input) , able to fax , print ) (the result no as good as te one - functoning device )
       • 3. Intenet telephone ( receiving and sending information )
         • VoIP ( VOICE OVER IP) (suport voice and se nternet to transfer it )
         • . Skype ( receive audio and images and will broadcast i into the internet and form into smething that human can nderstand)
