Monitorul

Un monitor afi eaz informa iile n form vizual, utiliznd text i

reprezentri grafice. Partea din monitor care afi eaz informa ii poart numele de ecran. La fel ca ecranul unui televizor, ecranului unuicomputer arat imagini fixe sau n mi care.

Exist dou tipuri principale de monitoare:monitoare CRT (cu tub catodic) i

monitoare LCD (afi aj cu cristalelichide). Ambele tipuri produc imaginiclare, dar monitoarele LCD au avantajulde a fi mult mai sub iri i

mai u oare. Totu i, monitoarele CRT Monitor LCD (stnga); monitor CRT (dreapta)sunt de obicei mai ieftine .http://windows.microsoft.com/ro-RO/windows-vista/Parts-of-a-computer#TopOfPageTarget

Dimensiuni ale diagonaleiIni ial, dimensiunile diagonale ale tuburilor folosite erau mici: 8, 9, 10,12, 14, 15 toli. n prezent, valorile uzuale ale monitoarelor de

tip CRT(cu tub electronic) sunt de 15, 17, 19, 20, 21, 22, 24 sau i 27 deoli.

Mrimea suprafa ial a unui ecran este determinat frecvent de distan a dintre dou col uri opuse ale acestuia. Este ns o problem, c metodade msurare nu face deosebire ntre formele geometrice exacte alemonitoarelor cu mrimi de diagonal identice, n sensul c suprafa adeterminat de o diagonal scade (n raport cu cele ptrate), cu ct

ecranele devin mai dreptunghiulare. Spre exemplu, un monitor 4:3 21"are o suprafa de ~211 oli ptra i, n timp ce unul 16:9 21" are o suprafa de numai ~188 oli ptra i.

ImprimantaO imprimant transfer date dintr-un computer pe hrtie.

Nu ave i nevoie de o imprimant pentru a utiliza computerul, dar dac de ine i una ave i posibilitatea s imprima i mesaje de po t electronic , felicit ri, invita ii, anun uri i alte materiale. De asemenea, multe persoane prefer s imprime acas propriile fotografii.

Cele dou tipuri principale de imprimantesunt imprimantele cu jet de cerneal i

imprimantele laser.Imprimantele cu jet

de cerneal sunt imprimantele cele maiobi nuite pentru acas .

Acestea pot impri-

PlotterulPlotter-ul este un echipament care actioneaza in mod automat unsistem mecanic de varfuri de scriere si este utilizat pentru

imprimarea graficelor de mare rezolutie, diagrame bazate pe linii,planuri si foarte des pentru sistemele CAD.

Plotter-ul functioneaza realizand imaginea printr-un sistem vectorialde unire a punctelor printr-o serie de linii cu ajutorul varfurilor descriere.

Exista doua tipuri de plottere: flatbed plotters si drum plotters.Plotterul flatbed va desena diagramele pe o hartie fixata pe otableta plata in timp ce drum plotter-ul poate imprima pe suprafetefoarte mari de hartie.
