### UNDERSTANDING THE COMPUTER REGISTERS.

REGISTERS AND ITS USES IN COMPUTER WORLD. REGISTERS AND ITS USES IN COMPUTER WORLD. “IN THIS LIFE, ALL WE HAVE IS MEMORY! ” THIS EXCLAMATORY SENTENCE IS USED BY MANY FILM MAKERS IN THEIR DIALOG.  SO DOES IT ACTUALLY MEAN SOMETHING TO THEM?  YES IT DEFINITELY MEANS EVERYTHING TO THEM AND US.  THAT’S WHY THEY SHOW THEM IN THEIR CINEMA (MOVIE, FILM WHATEVER YOU SAY).  MEMORIES MEAN EVERYTHING THAT IS STORED IN OUR BRAIN AFTER WE EXPERIENCE IT AND THEN USE IT AS A LESSON FOR LIFE  OR ENTERTAINMENT PURPOSE. HUMANS AS WELL AS ALL LIVING BEINGS DO THAT.  BUT OUR TOPIC IS  “WHAT ARE REGISTERS? WHY DO COMPUTERS NEED THEM?” SO HERE WE BEGIN. THE DISCRETE ELEMENTS OF INFORMATION IN A DIGITAL COMPUTER MUST HAVE A PHYSICAL EXISTENCE IN SOME INFORMATION STORAGE MEDIUM.  FURTHERMORE, WHEN DISCRETE ELEMENTS  OF INFORMATION ARE REPRESENTED IN BINARY FORM, THE INFORMATION STORAGE MEDIUM MUST CONTAIN BINARY STORAGE ELEMENTS FOR STORING INDIVIDUAL BITS.   A BINARY CELL IS A DEVICE THAT POSSESSES TWO STAB

### HOW DO COMPUTERS UNDERSTAND BINARY LOGIC

HOW DO COMPUTER UNDERSTAND THE BINARY LOGIC?   As we have shown in the previous post  LANGUAGE THAT COMPUTER AS WELL AS HUMAN UNDERSTAND  I am going to dig deep of that topic in this post.  I will try to explain how computer understand the binary logic.   So lets begin.   I am going to write about binary logic, that most of the computer manufacturers and developers use.                  Binary logic deals with variables that take on two discrete values and with operations that assume logical meaning.   The two values the variables take may be called by different names (e.g. true and false, yes and no, etc.), but for our purpose it is convenient to think in terms of bits and assign the values of 1 and 0.     Binary logic is used to describe, in a mathematical way, the manipulation and processing of binary information.   It is particularly suited for the analysis and design of digital systems.   For example, the digital logical circuits of many circuits that perform binary

### 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
