RULES OF LOGIC ---> INTERNET PROTOCOL

 RULES OF LOGIC---->INTERNET PROTOCOL FRIENDS, TODAY I AM GOING TO DISCUSS SOMETHING ABOUT IP ADDRESSING.  IP IS A LOGICAL ADDRESS FULLFORM INTERNET PROTOCOL.  IT PROVIDES LOGICAL ADDRESS TO NETWORKING DEVICES.   THESE ADDRESSES ARE USED TO DEFINE SOURCE AND DESTINATION OF DATA PACKETS IP HAS TWO VERSIONS 1. IP VERSION 4 2. IP VERSION 6 IP VERSION 4 IT IS 32 BIT ADDRESS WRITTEN IN DECIMAL NUMBER  FORMAT  192.168.1.1 THE NUMBERS IN THE DIGITS LIKE 192.68.1.1 HERE EVERY NUMBER BEFORE THE DOT IS AN OCTET. HERE IT IS SHOWN THAT EACH DIGIT IS PRECEDED BY DOT IS AN NUMBER BELONGING TO AN OCTET LIKE FIRST OCTET, SECOND OCTET , THIRD OCTET AND FOURTH OCTET. EACH OCTET IS AN NUMBER IN BINARY FORM WRITTEN IN 2^8=256 BINARY FORM HERE THE DIGIT SHOWS THAT A VARIABLE IS IN THE BY POWER OF 2, HERE I WANT TO SAY THAT AS COMPUTER UNDERSTANDS BINARY DIGIT IN WHICH THE VARIABLES ARE 0 AND 1.  AS THE COMPUTER UNDERSTANDS BINARY DIGIT SO IT HAS ONLY 2 VALUES. HENCE THE POWER IS WRITTEN IN 2. SO THE

SUBTRACTION IN COMPUTERS

SUBTRACTION IN COMPUTERS H OW DO COMPUTERS SUBTRACT IN ANY EQUATION? Computer is one of the best inventions in the whole world. Now in the era of electronics, computers are shrinking in the size.   The dream of having pocket computers which was shown in many Hollywood as well as many film industry is now a reality.  Many unimaginable discoveries and inventions are done with the help of computers. As in this age the   of semiconductors and embedded systems we are achieving what was a dream, about 60-70 years ago. Now to achieve such a dream, the hard-work and dedication needed was given by many scientists whose aim was to uplift the society.   Now if we want to invent something we need good hold on arithmetic computation.   This computation was understood and logically implemented by many scientists and engineers.   We use Complements   in digital computers for almost   simplifying the subtraction operation and for logical manipulations and computations.
