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


FILE SYSTEM AND FORMATING In this post i am going to teach you about various types of file system and formating used in computers. So lets start. The file system dictates how information is organized on the disk.   For example, the file system determines hjow large the allocation unit, or storage unit, the file is.   The following sections introduce the different file systems available and the os’ s that support them. The FAT FILE SYSTEM – the file allocation table (fat) file system has been the most popular file system up until the last few years.   The file system is designed for the small disk and simple folder structures.   it resides in the beginning of the system. It keeps two copies of the data in its table as back up so that if any copies become corrupted it can cure that corruption.   The file allocation table along with the root folder should be kept on fixed position so that boot files can be perfectly located.   The file allocation table (fat)


  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 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


LOGICAL DESIGN OF FUNCTION OF INTEGRATED CIRCUITS A binary variable or called as two value variables can take the value of 0 or 1.  A Boolean functions or named as two variable function is an expression formed with binary variables, the two binary operators OR and AND, the unary operator NOT, parenthesis, and equal sign.  For a given value of the variables to made it as good and thorough, the function can be either 0 or 1.  Consider, for example, the Boolean function:                                                  F1 = xyz’ The function as shown above F1 is equal to 1 if x = 1 and y = 1 and z’ =  1; otherwise F1 = 0.  The above is an example of a Boolean functions represented as an algebraic expression.  A Boolean function may be represented in a truth table.  To represent a function of a truth table we need a list of 2^n combination of 1s and 0s of the n binary variables and a column showing the combinations for a function equal to 0 or 1. As shown in Table below, th


ANOTHER TYPE OF WINDOWS INSTALLATION: MIGRATION INSTALLATION There are total three types of installation of windows 8.1.  Namely clean installation, upgrade installation and migration.  All of the three are important to learn.  But in this post i am going to tell you something about migration which is a most important type of installation.  So let us begin A clean installation of windows 8.1 is required before installation windows 8.1 by using migration scenario, followed by the migration of the user setting data from the older version of windows operating system to windows 8.1.   Depending upon your business environments, use two migration scenarios : side by side migration and inplace migration also known as refresh computer scenario. Both migration scenario require a clean installation of windows 8.1.   Migrating previous configuration from an old operating system requires to moving files and settings to clean installation of a windows 8.1 operating system.
