2. What you learn todayCompTIA A+ 220-701 , Section 1.10Install and configure peripheral and input devices. - Keyboard - Mouse - Barcode Reader - Multimedia - Biometric Devices - Touch Screen - KVM Switch

3. Keyboard Installation Newer Keyboard might have both Mini-Din (PS/2) and USB - Use one or the other.Additional feature may require additional driver or software.

4. Mouse Newer mouse might have both Mini-Din (PS/2) and USB - Old mouse use the serial port.New Optical mouse few moving parts - May need the right surface.

5. Bar Code Reader Mini-Din (PS/2) and USBLaser Scanner can be seen - You can see it, right?A Separate reader may be required for testing.

6. Digital CameraStill Pictures - Now with video.Pixel Density - Megapixels Storage - Compact Flash - Secure Digital - Other formats

7. Web CameraWebcamsUSB connectionsLive Video - Not often Used for stored video/pictures on the computer. Integrated into new Laptops

8. Digital Video CamerasLatest generation video capture.Storage - Hard drives - Flash Memory ( Compact Flash (CF), Secure Digital (SD), Internal Memory.Connectivity - IEEE 1394/ Firewire/ i.Link - HDMI - USB

9. Transferring Pictures and VideoConnection - USB - Firewire - memory cardsLong-term Storage - Pictures - Video

10. MicrophoneIntegrated into most new laptops and multimedia devices.Analog or USB connections

11. MIDI MIDI – Musical Instrument Digital Interface - Industry Standard since 1983.New connection use USB or Ethernet.

12. BiometricFingerprint Readers

13. Touch ScreensYou require Stylus.

14. KVMUse many computers with single keyboard, Video display, and mouse.KVM – keyboard-video-mouse.
