HOW CALCULATORS WORK ?? EVER THOUGHT OF...

1. HELLO AND WELCOME GUYS TO MY BLOGS

GUYS YOU ALL KNOW ABOUT CALCULATORS EVER THOUGHT HOW THEY WORK STAY TUNED TO KNOW MORE ABOUT CALCULATORS....

GUYS SMARTPHONES HAVE JUST LAUNCHED FEW YEARS AGO BUT CALCULATOR IS A DEVICE WHICH IS BEEN USED FROM MANY YEARS

SO WHAT IS THE SCIENCE BEHIND THEM WHAT IT CONSISTS THAT THE CALCULATOR GIVES THE ANSWER IN JUST A FRACTION OF SECOND NO MATTER HOW BIG THE NUMBER IS

NOW SEE THIS IS ALSO AN ELECTRONIC DEVICE AND IF YOU TRY TO OPEN YOU WILL GET VERY SIMPLE CIRCUIT AND YOU WILL THINK WHY DID YOU OPENED IT AND YOU WILL NOT GET ANY IDEA OF WHAT IS THERE INSIDE AND HOW THIS THING WORKS

        2. COMPONENTS OF A CALCULATOR

• COMPLETE CIRCUIT BOARD
• BASIC DISPLAY
• SOLAR PANEL (MOSTLY)
• SMALL BATTERY
• KEYPAD

AND YOU CAN SEE A PROCESSOR ON THE MAIN BOARD WHICH DO ALL THE CALCULATIONS WITHIN SECONDS

        3. NOW ON THE TOPIC

NOW I WILL TALK ABOUT A VERY SIMPLE CALCULATOR THAT HOW IT WORKS. THE VERY FIRST THING IS THE INPUT, IF YOU WANT TO ENTER ANY NUMBER FOR EXAMPLE 200+300 OR ANY RANDOM NUMBER. WHEN YOU ARE ENTERING THE NUMBER AT THAT TIME THE KEYPAD SAME LIKE THE KEYPAD OF THE REMOTE OF YOUR T.V. THE CALCULATOR ALSO HAS A KEYPAD. BASICALLY IT IS A MEMORY, WHEN YOU PRESS ANY BUTTON ON THE KEYPAD IT CONTACTS WITH THE CIRCUIT AND THE PROCESSOR COMES TO KNOW WHICH PARTICULAR KEY YOU HAVE PRESSED AND THAT NUMBER IS SHOWN ON THE DISPLAY OF THE CALCULATOR. I WILL TALK LATER ABOUT THE DISPLAY OF THE CALCULATOR

AND AFTER TYPING THE NUMBERS WHEN YOU PRESS ANY EXTRA SYMBOL LIKE PLUS(+),MINUS(-),MULTIPLY(x) OR DIVIDE(/) THE NUMBER YOU TYPED ARE STORED INTO THE CALCULATOR'S MEMORY, NOW AFTER TYPING THE SECOND NUMBER WHEN YOU PRESS THE EQUALS TO(=) BUTTON THE RESULT IS SHOWN ON THE DISPLAY

            4. BUT HOW THE RESULTS COME VERY FAST ???

SO THE THING HERE IS COMPLETE CALCULATION, LIKE WE HUMANS WE CAN COUNT EASILY LIKE 1,2,3,4,5,6..... BUT THE COMPUTER DOSN'T UNDERSTAND THIS COUNTING THE COMPUTERS HAVE ONLY TWO STATS THAT ARE 1 AND 0 (ON OR OFF). SO THE NUMBERS YOU HAVE TYPED ON THE CALCULATOR HAVE TO CONVERTED IN THE COMPUTER LANGUAGE WHICH IS CALLED THE BINARY LANGUAGE (IN THE FORM OF 1 AND 0)AND AFTER CALCULATING THE RESULT IS SHOWN ON THE DISPLAY OF YOUR CALCULATOR
