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…

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 akind of computer data storage which will detect and proper the more common types of internal data corruption in simple words with firmness and boldness.

OPERATING SYSTEM- AN INTERFACE?

ALL ABOUT OPERATING SYSTEM
An operating system is program that acts as an interface between the user and the hardware of the computer.  It also manages the components of the machine such as processor management, disk resource management, input output files, devices etc.
The operating system can be classified on various parameters. In this section we will learn the classification of the operating system based on the number of user and the number of task performed by operating system that run simultaneously on the computer.
So lets begin CLASSIFICATION BASED ON THE NUMBER OF USER
Based on the number of people accessing the computer, the operating system can be classifiednamely in two types namely single user or multi user.As shown in list below
SINGLE USER :-in this type of operating system only one users can access the resources of the operating system at a time.Example of single user include dos and microsoft windows
MULTI USER :- in this type of operating system more than one user can simult…

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…

DIVISIONAL FACTS OF OPERATING SYSTEM

OPERATING SYSTEMS DIVISIONAL FACTS

An operating system is a software program that acts as an interface between the user and the hardware of the computer.  It also manages the components of the machine such as processor management, disk resource management, input output files, devices etc.

Some of the operating system i am going to show you.  So lets get started User interface :  the user interface allow the user to interact with the machine.  There are two types of user interface given by the user interface developers.  They are as follows 1.Character line user interface such as linux redhat 2.Graphical line user interface such as windows operating system In character line user interface the user have to interact with the computer by giving commands that’s why it is also called as command line interface.

In graphical user interface this control is given to the user where the user with mouse or keyboard will control the command or an object kept on the desktop of the computer.  For exa…

HARDWARE COMPONENTS OF COMPUTER A LITTLE SUMMARY

HARDWARE COMPONENTS- INPUT AND OUTPUT COMPONENTS In this topic we discuss the major hardware components of a microcomputer system, which are used for input, output, processing, storage, electrical supply and communication.
Most input and output devices are outside the computer case.Most processing and storage components are contained inside the case.The most important component in the case is the central processing unit (CPU) is called the processor and microprocessor.
As its name implies, the device is central to all processing done by the computer.Data received by input devices is read by the cpu , and output from the cpu is written to output devices.The cpu writes data and instruction in storage devices and performs calculation and other data processing.
Whether inside or outside the case and regardless of the function the device performs,each hardware input, output, or storage device require these elements to operate:
A method for the CPU to communicate with the device
·The device send…
