UNDERSTANDING THE COMPUTER REGISTERS.

 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 stable states and is capable of storing one bi

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

EXPANSION SLOTS IN MOTHERBOARD

EXPANSION SLOTS IN MOTHERBOARD  Friends today i am going to share my knowledge and understanding of the expansion slots. So lets begin with our topic. Expansion slots are used to provide additional properties for carrying the computation task such as additional video, audio and sound, advanced graphics and Ethernet.   So lets begin with our knowledge hunting. I will start by AGP expansion slots. AGP AGP stands for ACCELARATED GRAPHICS PORT.  AGP was introduced with high speed 3D graphics display in 1996.  It is used for older graphics card types which is discontinued by PCI EX16 graphics port in 2005.   These were kernel version of AGP most of the brand in 1.5 volt DC.  AGP 1x channel and 66MHZ clock speed resulting a data table of 266 MBPS.   AGP 2x, 4x ,8x specification multiply MHZ clock to produce increase throughput. AGP 8x produces effective clock frequency of 533 MHZ resulting a throughput of 2 GBPS (2133MHZ) resulting a throughput of over a 32 bit channel. PCI PCI  stands for P

CODES OF LANGUAGE IN COMPUTER SYSTEM. WHAT ARE THE OTHER CODES WHICH ARE USED IN COMPUTER SYSTEM?

  CODES OF LANGUAGE IN COMPUTER SYSTEM.   WHAT ARE THE OTHER CODES WHICH ARE USED IN COMPUTER SYSTEM?   There are many codes in computer system which may remain unnoticed by many computer geeks and nerds.   I also first didn’t see it but I am going to share it because these are important codes and used by many computer hardware developers, vendors and computer software developers.    They are mostly understood by ELECTRONICS AND ELECTRICAL ENGINEERING geeks or nerds.   They are as under : ·         ERROR DETECTION CODES ·         ALPHANUMERIC CODES ·          REFTLECTED CODES First we will discuss something about ERROR DETECTION CODES.                                                                                                              ERROR DETECTION CODES:   Binary information , be it pulse modulated signals or digital computer input or output, may be transmitted though some form of communication medium or electrical wires or radio waves.   Any external noi

ARITHMETIC CALCULATION IN COMPUTERS

ARITHMETIC OPERATION AND CONVERSION DONE BY COMPUTER As we have seen in previous post that arithmetic computation is an important thing in calculation, if a person doesn’t know arithmetic computations,   he will be doomed to be in trouble during calculations that happens   in everyday life.   So it is necessary to learn arithmetic computation.   So in this post I am going to take one step further.   I am going to write about octal and hexadecimal numbers. Now let us discuss some arithmetic conversion.   Let us see what is octal and hexadecimal numbers used by digital computer. The conversion from and to binary, octal and hexadecimal plays an important part in digital computers.   Since 2 3 = 8 and 2 4 = 16 each octal digit corresponds to three binary digits and each four binary digit corresponds to one hexadecimal digit.   The conversion of from binary to octal is easily accomplished by partitioning the binary into group of three digit each, starting from binary

SUMMARY OF MEMORY

RAM PROPERTIES Friends in the last post i tried to explain the different types of ram as well as given the details of its similarities now i am going to show you how the properties of ram can be judged . SO LET US BEGIN. SINGLE SIDED VS DOUBLE SIDED DIMMS or DUAL INLINE MEMORY MODULE whatever you call are often referred to as single chip or double sided to describe whether the chips are located on one or both of the modules printed circuit board . However these terms may cause confusion or distract you from the topic, as the physical layout of the chips does not necessarily relate to how they are logically organized or accessed in whatever terms you are told. ERROR CORECTING CODE MEMORY (ECC MEMORY) An ERROR CORRECTING CODE (or ECC) whatever general public says  could be a   kind of  computer data storage  which will  detect  and proper  the more common  types of  internal data corruption in simple words with firmness and boldness. Most computers or workstati
