SSS 1lide  * TTDntrodkction to Dnpkt jevicesTT
# TTjeynitionTT* Dnpkt devices are hardware that allows ks to send data and instrkctions to a compkter-E
# TTKxamplesTT*E
E # TTMeuIoardTT* Wo tupe letters and nkmIers
E # TT3okseTT* Wo move the ckrsor and select thinbs on the screen
E # TT1cannerTT* Wo copu dockments and pictkres onto the compkter
# TTDmportanceTT* githokt inpkt devices/ we wokldn’t Ie aIle to interact with compkters or bive them commands- Wheu help ks tal. to the
compkter-

SSS 1lide J* TT(atebories of Dnpkt jevicesTT
# TT3ankal Dnpkt jevicesTT*
E # jevices we control with okr hands-
E # TTKxamplesTT* MeuIoard/ 3okse/ Aoustic.-
# TTBktomatic Dnpkt jevicesTT*

2. E # jevices that wor. aktomaticallu to send data to the compkter-
E # TTKxamplesTT*E
E E # TT1cannerTT* Bktomaticallu copies imabes to the compkter-
E E # TTRarcode ;eaderTT* ;eads the lines )IarcodeY on prodkcts to ynd information-
# TTjifferenceTT* 3ankal devices need okr control4 aktomatic devices wor. Iu themselves-

SSS 1lide q* TTgor.inb Principle of a MeuIoardTT
# TTHow Dt gor.sTT*
E # ghen uok press a .eu/ the .euIoard sends an electrical sibnal to the compkter-
E # Kach .eu has a kniFke code )scan codeY that the compkter knderstands-
E # “or example/ pressinb the letter ”B— sends a speciyc code/ and the compkter shows ”B— on the screen-
# TTKxampleTT* Whin. of it as pressinb a Iktton to libht kp a IklI5the Iktton is the .eu/ and the libht is the letter on the screen-

SSS 1lide U* TTWrokIleshootinb a MeuIoardTT
# TT(ommon DsskesTT*
E # TT'nresponsive .eusTT* 1ometimes .eus stop wor.inb-
E # TT1tkc. .eusTT* B .eu mau bet stkc. and repeat-
E # TT(onnection proIlemsTT* Whe .euIoard mibht not Ie connected properlu-
# TTRasic WrokIleshootinbTT*
E # TT(lean the .euIoardTT* 'se a soft Irksh or Ilower to remove dkst-
E # TT(hec. the connectionTT* 3a.e skre the '1R is properlu plkbbed in or reconnect if it6s wireless-
E # TT'pdate driversTT* 1ometimes uok need to install new software to ma.e the .euIoard wor. properlu-

3. SSS 1lide 7* TTgor.inb Principle of a 3okseTT
# TTHow Dt gor.sTT*
E # Whe mokse moves on a skrface/ and sensors in the mokse detect the movement-
E # Bn optical mokse kses libht to trac. movement/ while a mechanical mokse kses a Iall-
E # Whe mokse sends the information to the compkter/ and the ckrsor moves accordinblu-
# TTKxampleTT* Whin. of the mokse as a remote control for the ckrsor on uokr screen- ghen uok move it/ the pointer follows-

SSS 1lide z* TTWrokIleshootinb a 3okseTT
# TT(ommon DsskesTT*
E # TTPointer not movinbTT* Whe mokse mibht stop wor.inb or free8e-
E # TTKrratic movementsTT* Whe pointer moves randomlu-
E # TT(onnection isskesTT* Kspeciallu with wireless mice/ the connection can drop-
# TT1olktionsTT*
E # TT(lean the mokseTT* gipe the skrface where uok kse the mokse/ and chec. for dirt on the sensor-
E # TT(hanbe IatteriesTT* “or wireless mice/ dead Iatteries cokld Ie the isske-
E # TT(hec. the connectionTT* Df it’s a wired mokse/ chec. if the caIle is connected- “or wireless/ reconnect via Rlketooth or '1R-

SSS 1lide 9* TTgor.inb Principle of a 1cannerTT
# TTHow Dt gor.sTT*
E # Whe scanner shines libht onto the dockment or imabe-
E # Whe re0ected libht is converted into dibital sibnals-
E # Whese sibnals are processed Iu the compkter and tkrned into an imabe or text yle-
# TTKxampleTT* Dmabine ta.inb a photo of uokr dockment- Whe scanner does this Ikt in a more detailed wau-

SSS 1lide O* TTWrokIleshootinb a 1cannerTT
# TT(ommon DsskesTT*
E # TTPoor imabe FkalituTT* Whe scanned imabe is Ilkrru or knclear-
E # TT,o responseTT* Whe scanner doesn’t tkrn on or connect-
E # TTKrror messabesTT* Nok mibht see an error on uokr screen when truinb to scan-
# TT1olktionsTT*
E # TT(lean the scanner blassTT* jkst or smkdbes can affect the Fkalitu-
E # TT(hec. connectionsTT* Knskre the power caIle is plkbbed in and the '1R is properlu connected to the compkter-
E # TT'pdate driversTT* 1ometimes/ kpdatinb the scanner’s software yxes isskes-

SSS 1lide :L* TTgor.inb Principle of !ther Dnpkt jevicesTT
# TTAoustic.sTT*
E # 'sed for baminb and controls movement in bames-
E # Dt sends directional sibnals to the compkter Iased on how it6s moved-
# TTWokchscreensTT*
E # Bllows direct interaction Iu tokchinb the screen-
E # Whe screen detects the tokch and sends the location data to the compkter-
# TTRarcode ;eadersTT*
E # 1cans Ilac. and white Iars on prodkcts-
E # Whe reader converts the Iars into nkmIers and sends the information to the compkter-

5. SSS 1lide ::* TT(ommon WrokIleshootinb WechniFkesTT
# TTjriver DsskesTT*
E # jrivers are small probrams that allow inpkt devices to commknicate with the compkter-
E # TT1olktionTT* Df an inpkt device stops wor.inb/ tru reinstallinb or kpdatinb the driver-
# TT(onnection ProIlemsTT*
E # Loose caIles or wireless interference can stop devices from wor.inb-
E # TT1olktionTT* (hec. the caIles/ tru different '1R ports/ or reconnect wireless devices-
# TT(leaninb and 3aintenanceTT*
E # jirt can Iloc. sibnals or stop inpkt devices from wor.inb-
E # TT1olktionTT* ;ebklarlu clean uokr devices to enskre proper fknctioninb-

SSS 1lide : * TT(onclksionTT
# TT1kmmaruTT*
E # Dnpkt devices are essential for sendinb data to a compkter-
E # Mnowinb how theu wor. helps uok trokIleshoot them when somethinb boes wronb-
# TTDmportanceTT* 'nderstandinb Ioth the wor.inb and trokIleshootinb of these devices ma.es ksinb compkters easier and more eMcient-
