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 happensin 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 23 = 8 and 24 = 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 point and preceding to the left or to the right…

INTEGRATED CIRCUITS WITH A SOFTWARICAL TWIST

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, there are eight p…

ANOTHER TYPE OF WINDOWS INSTALLATION.

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.
Evaluating a migrating scenario In a…

FORMATS OF FILESYSTEM IN COMPUTER TECHNOLOGY

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) file system has been the most popular file system …
