In today’s world mathematics is a must learned subject .  In all the inventions and discovery , the main reason for their success of the practical’s are due to mathematics.  So in order to make a career in today’s world require mathematics. 

But this Is blog of computers science and information technology, then why should we read mathematics so it requires mathematics to understand the reason behind such technology.  So I am going to write something about mathematics for its uses and technology in the computer world.
One of the main aims of logic is to provide rules by which one can determine whether any particular argument or reasoning is valid (correct)
Logic is concerned with all kinds of reasoning whether they be legal arguments or mathematical proofs or conclusions in a scientific theory based upon a set of hypothesis.  Because of the diversity of their application these rules are called rules of inference, must be stated in general terms and must be independent of any particular language used in the arguments. 

More precisely, in logic we are concerned with the forms of argument rather than arguments themselves.  Like any other theory in science the theory of inference is formulated in such a way that we should be able to decide about the validity of an argument by following the rues mechanically and independently of our own feelings about the argument. 

Of course to proceed in this manner requires that the rules mechanically and independently of our own feelings about the argument.  Of course to proceed in this manner requires that the rules be stated unambiguously.

Any collection of rules or any theory needs a language in which these rules or theory can be stated.  Natural languages are not always precise enough.  They are also ambiguous and as such are not suitable for this purpose. 

It is therefore necessary first to develop a formal language called the object language.  A formal language is one in which the syntax is well defined.  In fact, every scientific discipline develops its own object language which consists of certain well-defined terms and well specified uses of these terms. 

The only difference between logic and other disciplined is that in other disciplines we are concerned with the use of the object language while in logic we are as interested in  analyzing of an object language without considering its use in the theory of inference. 

In order to avoid ambiguity we use symbols which have been clearly defined in the object languages.  An additional reason to use symbols is that they are easy to write and manipulate.  Because of use this symbols the logic that we shall study is also called symbolic logic, Our study of the object language requires the use of another language. 

For this purpose we can choose any of the natural languages.  In this case our choice is English and so the statements about the object language will be made in English.  This natural language (English) will them be called or meta language.  Certain inherent difficulties in this procedure could be anticipated.  Because we wish to study a precise language while using another language which is not so precise.

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


PROCESSOR AND HYPERTHREADING Friends in the last post i tried to say something about computer science and mathematics relationship.   Now i am going to say something about processor and hyperthreading.   So let’s get started. The Physical Component By Which A Computer Is Made Which We Can See, Touch And Feel Is Called Computer Hardware Example Ram, Motherboard. ·          INPUT DEVICE   : These hardware are used to input any data, instruction on command insidea computer device.   example keyboard mo9use scanner microphone, webcam etc ·          OUTPUT DEVICE :   these hardware are used to get any output from a computer system.   example: monitor, printer, speaker. ·          CENTRAL PROCESSIG UNIT (CPU) : This Device Proceses All Instruction Given By A User, And It Also Other Haqrdwqaar Peripherals Example   :Microprocessor ·          MOTHERBOARD: It is the main electric circuit board which is made by a pcb(printed circuit board).   It hods all hardware componen


  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
