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

UNIT- 3COMPUTER DEFINITION
* 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

UNIT- 4MOUSE
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
QUESTIONS AND ANSWERS
HOW THE POINTER LOOK LIKE ?
11
UNIT- 4HOW 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
UNIT- 4HOW 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
3) SERIAL PORT COENNECTION 2(PS2)
4) UNIVERSAL SERIAL BUS(USB)
13
UNIT- 4HOW THE PS2 / USB COENNECTION LOOKS ?
HOW THE PS2 / USB PORT COENNECTION LOOKS ?
PS2 USB
PS2 USB
14
UNIT- 4HOW MANY TYPES OF MOUSES ARE THERE ?
THERE ARE NUMBER OF POINTING DEVICE IN THAT A
SOME POINTING DEVICE ARE TO BE DISSCUSED
MECHANICAL MOUSE
TRACK BALL MOUSE
OPTICAL MOUSE
LASER MOUSE
AIR MOUSE
3D MOUSE
15
UNIT- 4 WIRELESS MOUSE
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
(DONGEL)
16
UNIT- 4 LASER MOUSEthese 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
OPTICAL MOUSEA 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.
UNIT- 4
18
UNIT- 4 TRACK BALL MOUSEA 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
UNIT- 4 MECHANICIAL MOUSEA 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
UNIT- 5KEYBOARD
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
UNIT- 5KIRAN: 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
UNIT- 5NOW 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
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 ………

UserUNIT- 6
USER MEANS PEOPLE THIS USER HAS DIVIED IN TO TWO TYPES
USER
PROFESSIONAL USEREND USER
END USER
A USER HAVING A BASIC/INTERMEDIATE SKILL IS KNOW AS AN END USER
PROFESSIONAL USER
A USER HAVING A BASIC/INTERMEDIA/EXCELLENT/SUPERB SKILL IS KNOW AS AN PROFESSIONAL USER
25
WHAT TO DO IS YOURS
UNIT- 6
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
