Computer basics

  1. 1. 1 Inside the CB you will learn about the topics prescribed below
  2. 2. 2 INDEX UNIT NO UNIT NAME SLIDES NUMBERS 1 COMPUTE 4 - 5 1.1 BODMAS RULE 6 - 7 2 COMPUTER FULL FORM 8 3 COMPUTER DEFENIATION 9 4 MOUSE 10 - 19 5 KEYBOARD 20 - 23 6 USER 24 7 WHAT TO DO IS YOURS 25
  3. 3. 3 Before going Inside the CB topics a important note ***IMPORTANT NOTE*** COMPUTER IS A CACULATING DEVICE IT IS THE FIRST STAGE OF THE COMPUTER THE VERY NEXT STAGE OF THE COMPUTER IS ELECTRONIC CALCULATOR LATER THEY DEVELOPED NUMBER OF COMPONETS WITH THE HELP OF ELECTRONICS AND THEY GIVEN THE DEFENIATION AS COMPUTERIS AN ELECTRONIC DEVICE
  4. 4. 4 COMPUTE MEANS “CALCULATION” WE HAVE MANY CALCULATION OPREATIONS SOME CALCULATION OPREATIONS ARE GIVEN BELOW SEE THE TABLE FOR THE COMPUTER OPREATION SYMBOLS CHANGE
  5. 5. 5 BASIC/COMPUTER MATHEMETICAL SYMBOLS BASIC MATHEMATICAL SYMBOLS COMPUTER MATHEMATICAL SYMBOLS
  6. 6. 6 THIS RULE SAYS HOW THE COMPUTER CALCULATE AND WEWILL KNOW THE FULL FORM OF BODMAS 1ST STEP  BRACKETS OPENING 2ND STEP  DIVISION 3RD STEP  MULTIPLICATION 4TH STEP  ADDITION 5TH STEP  SUBTRACTION THIS THE WAY COMPUTER START PROCESSING WHEN THE PROBLEM WAS GIVEN
  7. 7. 7
  8. 8. 8
  9. 9. 9 * COMPUETR IS AN ELECTRONIC DEVICE * IT TAKES INPUT FROM THE USER * IT PROCESS ,MANIPULATE AND EDIT THE DATA * IT REPRODUCES THE PROCESSED DATA AS A OUTPUT
  10. 10. 10 IN THIS CHAPTER YOU WILL KNOW ABOUT THE MOUSE AND IT CONNECTIONS IN QUESTION AND ANSWER METHOD WHAT IS MOUSE ? MOUSE IS A GUI POINTING AND INPUT DEVICE HOW THE POINTER LOOK LIKE ?
  11. 11. 11 HOW THE MOUSE LOOKS ? THERE ARE TWO PARTS OF THE MOUSE THEY ARE A)BUTTONS 1)LEFT & 2) RIGHT B)SCROLLER IS IN CENTER WHAT ARE THE PARTS OF THE MOUSE AND WHAT ARE THEY?
  12. 12. 12 HOW THE MOUSE IS CONNETCED? MOUSE CAN BE CONNETCED IN TWO WAYS 1) ANALOG 2) DIGITAL IN THE ANLOG WAY THE MOUSE HAVE TWO CONNECTIONS THEY ARE 1) SERIAL PORT COENNECTION 2(PS2) 2) UNIVERSAL SERIAL BUS(USB)
  13. 13. 13 HOW THE PS2 / USB COENNECTION LOOKS ? HOW THE PS2 / USB PORT COENNECTION LOOKS ?
  14. 14. 14 HOW MANY TYPES OF MOUSES ARE THERE ?
  15. 15. 15 A WIRLESS MOUSE IS AN CONNECTION OF DIGITAL THERE IS NO WIRE CONNECTED TO MOUSE IT WORK WITH THE HELP OF USB CONNECTION (DONGEL) WHEN IT IS CONNECTED THE MOUSE WORKS IF IT IS NOT CONNECTED THE MOUSE WILL NOT WORK
  16. 16. 16 these mice use laser beams to track movement and can be considered too be more accurate and precise than optical or trackball mice. Where an optical mousses LED would shine a bright red (or other colors), laser mouse have no shine and are usually invisible to the naked eye. The laser beam can also reflect on practically any surface, meaning there’s no need for mouse pads.
  17. 17. 17 A mouse that uses light to detect movement. because their sealed They work by emitting light from an LED or laser, and a CMOS sensor detects the light reflections as the mouse is moved.
  18. 18. 18 A trackball is a pointing device consisting of a ball held by a socket containing sensors to detect a rotation of the ball about two axes—like an upside-down mouse with an exposed protruding ball. The user rolls the ball with the thumb, fingers, or the palm of the hand to move a pointer.
  19. 19. 19 A MOUSE WHICH IS HAVING THE MECHANISIM WORKING WITH A BALL IS CALLED BALL MOUSE THIS MOUSE SHOULD HAVE MOUSEPAD IN THIS MOUSE THE POINTER WILL DEPEND OP ON THE MOMENT OF THE BALL
  20. 20. 20 IN THIS UNIT YOU WILL KNOW ABOUT THE CONNECTIONS OF KEYBOARD AND TYPES OF KEYBOARD IN THE MODE OF CONVERSASTION BETWEEN TWO PEOPLE NAMED KIRAN AND KASI KASI : HI KIRAN HOW ARE YOU? LONG TIME NO SEE WHY? KIRAN: FINE WHAT ABOUT YOU? KASI : FINE, I HEAR A WORD CALLED KEYBOARD, WHAT IS A KEYBOARD? KIRAN: FINE GOOD QUESTION KASI.I WILL EXPLAIN IT TO YOU, HAVE YOU SEEN A TYPEWRITER ? KASI : YA KIRAN: KEYBOARD BEFORE STAG IS TYPEWRITER, THEY DEVELOPED THE TYPEWRITER WITH THE HELP OF ELECTRONICS AND NAMED AS KEYBOARD
  21. 21. 21 KIRAN: HAVE YOU SEEN A KEYBOARD? KASI : NO KIRAN: YOU WANT TO SEE THE TYPEWRITER AND KEYBOARD? KASI :YES,BUT WHERE IN MY FRIENDS HOME, WHATIS HIS NAME AND WHERE IS HIS HOUSE? KIRAN: WALKBLE DISTANCE TO HIS HOME FORM HERE AND HIS NAME IS ASHWAN OK. KASI : FINE A FEW MINIUTES LATER KASI/KIRAN WAS IN THE HOUSE OF ASHWAN AND THEY INTRODUCED THEM SELF KIRAN: KASI COME HERE NOW SEE THIS THINGS ON THE RIGHT YOU SEE TYPEWRITER AND ON THE LEFT YOU SEE KEYBOARD FINE KASI : FINE
  22. 22. 22 NOW YOU CAN SEE THE TYPEWRITER ON THE RIGHT SIDE AND KEYBOARD ON THE LEFT SIDE KIRAN: NOW LET’S MOVE TO KEYBOARD ,KEYBOARD IS INPUT DEVICE WHICH TAKES DATA FROM THE USER TROUGH THE KEYBOARD HOW THE MOUSE CONNECTIONS ARE PROVIDED SAME AS THE KEY BOARD PS2/USB AND WIRELESS KEY BOARD IS ALSO PRSENT ON SEEING THE KEY BOARD WE SEE THE TING AS FOLLOW
  23. 23. 23 KIRAN: 1) CHARACERTS A-Z (26) 2) FUNCTIONAL KEYS F1-F12 (12) 3) NUMERICAL KEYS 0-9 (10) 4) ARROW KEYS - (4) 5) SPECIAL KEYS (ALT+CTRL) (2) THERE ARE TWO TYPES OF KEY BOARD • STRANDARD KEY BOARD (101/102 KEYS) • NON-STRANDARD KEYBOARD KASI : OK THANKS KIRAN BYE……… KIRAN : BYE TAKE CARE ………
  24. 24. 24 USER MEANS PEOPLE THIS USER HAS DIVIED IN TO TWO TYPES PROFESSIONAL USEREND USER A USER HAVING A BASIC/INTERMEDIATE SKILL IS KNOW AS AN A USER HAVING A BASIC/INTERMEDIA/EXCELLENT/SUPERB SKILL IS KNOW AS AN
  25. 25. 25 ASK YOU SIR OR FRIEND OR PARENTS OR SRUF IN INTERNET ? WHAT IS 3D MOUSE AND WHERE IT IS USED ? WHAT IS AIR MOUSE ? DIFFERNCE BETWEEN LASERMOUSE AND OPTICAL MOUSE ? HOW MANY PIN SLOTS ARE AVILABLE FOR PS PORT ? WHAT IS DATA ? WHAT IS FULL FORM BASIC ? AFTER COMPLETLY STUDYING THIS CHAPATERS CREATE POINTS TO REMEMBER TO YOUR OWN
