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

CHIPSETS OF COMPUTERS.

A CHIPSET IS A COLLECTION OF CHIP OR CIRCUITS THAT PERFORM INTERFACE AND PERIPHERAL FUNCTION FOR THE PROCESSOR.   THIS COLLECTION OF CHIPS IS USUALLY THE CIRCUITS THAT PROVIDES INTERFACES FOR MEMORY EXPANSION CARDS AND ONBOARD PERIPHERALS AND GENERALLY DICTATES HOW A MOTHERBOARD WILL COMMUNICATE WITH THE INSTALLED PERIPHERALS. CHIPSET ARE USUALLY GIVEN A NAME AND MODEL NUMBER BY THE ORIGINAL MANUFACTURER AND MODEL ALSO TELL YOU THAT YOUR PARTICULAR CHIPSET HAVE A CERTAIN SET OF FEATURES EG TYPE OF RAM SUPPORTED TYPE AND BRAND OF ONBOARD AND SO ON. CHIPSETS CAN BE MADE UP ONE OR MORE INTEGRATED CIRCUIT CHIPS.   INTEL BASED MOTHER BOARDS TYPICALLY USE TWO CHIPS.   THE FUNCTION OF CHIPSETS CAN BE DIVIDED INTO TWO MAJOR FUNCTIONAL GROUPS CALLED NORTH BRIDGE AND SOUTH BRIDGE. NOW I AM GOING TO SHOW YOU SOME OF THE BASIC CHIPSET IN COMPUTERS AND WIDELY USED CHIPSETS USED IN MODERN COMPUTERS .   THEIR NAMES AS 1) NORTH BRIDGE 2) SOUTH BRIDGE SO LET US BEGIN IN OUR LITTLE JO

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

IS DIGITAL COMPUTERS ARE VALUABLE?

DIGITAL COMPUTERS Today computers are used extensively in every day life.  It is used in basic as well as industrial, scientific and commercial purposes.  Our space program would not have been well developed without the real time monitoring of the machine of the spacecraft which was going to land on moon or any other planet of the scheduled program or launching of satellites on the orbit of earth. This is the scientific purpose i told you about while it has commercial purposes.  Like automatic data processing which the business enterprise uses. It has many works in educational purposes for example multiple choice question answers can be checked without any error and then the results can be printed out automatically with the help of the printer which is connected to the digital computer.   Digital computer are also used in air traffic control to control the aviation industry to help them control the planes by sending them data about the distance between the planes and t

THEORITICAL ALGEBRA IN COMPUTERS

ALGEBRA IN COMPUTERS Algebra is a subject in which the problem of the sum is solved with the help of letters (I mean the letters of English language as well as Greek language).  It is mostly used by the mathematicians, engineers, scientist as well as businessmen to solve any problem of the world.  Algebra is very important in many science as well as commerce studies.  So we are going to dig deep in algebra used in computers. We will consider Boolean algebra as it is used by the computers to solve real life problems.  So let us begin. Boolean algebra, like any other     mathematical system , may be with a set of elements , a set of operators and a number of unproved axioms or postulates.    A set of elements is any collection of objects having a common property.  If S is a set and x is an element of that set the x€ S denotes that x is an element of that set.   A set with de-numberable (means a small number) number of elements is specified by braces:  A={1, 2, 3, 4} tha
