3. Softcopy Output:Display Screen Screen Clarity: Dot pitch(nokta aralığı)(pd):the amount of space between the centers of adjacent pixels. Dot pitch(nokta aralığı)(pd):the amount of space between the centers of adjacent pixels. The closer the dots, the crisper the image Resolution(çözünürlük):The image sharpness of display screen. Resolution(çözünürlük):The image sharpness of display screen. The more pixel there are per square inch the finer the level of detail attained. Refresh rate: The number of times per second that teh pixels are recharged so that their glow remains bright. Refresh rate: The number of times per second that teh pixels are recharged so that their glow remains bright.

4. Softcopy Output:Display Screen Type of Monitor: CRT(Cothode ray tube): A vacuum tube used as a diplay screen in a computer or video display. CRT(Cothode ray tube): A vacuum tube used as a diplay screen in a computer or video display. Flat-panel displays: Made up of two plates of glass with a substance in between them in which light is manipulated. Flat-panel displays: Made up of two plates of glass with a substance in between them in which light is manipulated. By the substance between the plates of glass By the arrangement of the transistors in the screen

5. Softcopy Output:Display Screen Type of Monitor: substance between the plates: substance between the plates: LCD(Liquid crytal Display): consist of a substance called liquid crystal, the molecules of which line up in a way that alters their optical properties. EL(Electroluminescent): display contains a sustance that glows when it is charged by an electric current. Gas-Plasma: Display is like a neon bulb, in which the display uses a gas that emits light in the presence of ana electric current. Arrangments of transistors Arrangments of transistors Active matrix (TFT): Each pixel on the screen is controlled by its own transistor. Passive Matrix: A transistor controls a whole row or column of pixels.

8. Hardcopy Output:Printers A Dot-matrix printer:Contains a print head of small pins. Ink-jet printer: Spray small, electrically charged droplets of link from nozzles through holes in amatrix at high speed onto paper. Laser Printer: Works as a Photocopying machine. İmages are produced on a drum, treated with a magnetically charged ink-like toner and then transferred from drum to paper.

9. Hardcopy Output:Printers Thermal Printer: Characters are formed by heated elements being placed in contact with special heat sensitive paper forming darkened dots when the elements reach a critical temperature.
