  7. 7. How do input peripheralswork?When a user press a key, one electric switchis closed.A chip detects that event and save it in abuffer.When its possible, the information goes outthe buffer to be encoded in zeros and ones,code which is sent to the computer throughthe input port.Processor receives the data and processesit as the application or operating system maydecide.Userpressesa keyBufferEncodingPS/2Processor (CPU)d01100010R3-C4Keyboard

  9. 9. Output PeripheralsCharacteristicsThe screen size is measured ever inINCHES.Resolution is expressed as a productof pixels: 800 x 600, 1024 x 768, etc.Printers are characterized by theirspeed (in pages per minute, ppm) andtheir resolution (in dots per inch, dpi)

  12. 12. ConclusionPeripherals are deviceswhich can be connected tothe computer.They allow the introductionand exit of data.We can sort them as:Input Peripherals,Output Peripherals, andInput/Output PeripheralsKeyboard and Mouse are themost important InputPeripherals. Cameras, Webcamsand Scanners are InputPeripherals too.Monitor and Printer are mainOutput Peripherals.Hard Disk drives, MemorySticks, Re-writeable Disks, andexternal connections (Ethernet,Modem) are Input/OutputPeripherals.
