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


SUBTRACTION IN COMPUTERS H OW DO COMPUTERS SUBTRACT IN ANY EQUATION? Computer is one of the best inventions in the whole world. Now in the era of electronics, computers are shrinking in the size.   The dream of having pocket computers which was shown in many Hollywood as well as many film industry is now a reality.  Many unimaginable discoveries and inventions are done with the help of computers. As in this age the   of semiconductors and embedded systems we are achieving what was a dream, about 60-70 years ago. Now to achieve such a dream, the hard-work and dedication needed was given by many scientists whose aim was to uplift the society.   Now if we want to invent something we need good hold on arithmetic computation.   This computation was understood and logically implemented by many scientists and engineers.   We use Complements   in digital computers for almost   simplifying the subtraction operation and for logical manipulations and computations.  


PREPARATION AND HARDWARE REQUIREMENTS FOR WINDOWS 7 . Today’s   age is the age of computers.   Computer literacy is a must to survive in this age.   If you are not educated then this age will eat you.   So I will teach you some advanced matters of the computers.   So lets get started. Decades together Windows operating system rules the computing world because of its user friendly look and feel in this topic I will teach you some hardware requirements and preparing materials of windows 7. Microsoft windows 7 introduces advanced features that help users intuitively view , find and organize information on the computer but it will be shown in another   post.   Windows 7 delivers good personal productivity and digital environment on this computer. Now I am going to show you some hardware requirements of editions of windows 7.   So lets get started. Hardware Requirements Windows 7 Starter and Windows 7 Home Basic editions require; ·          1 GHz 32-bit (x86) or


What is windows to go? Windows to go is an important deployment option in windows 8.1 and above.   Windows to go assist to deploy the windows 8.1 enterprise to a specialy prepared usb storage device and then use this usb storage to start any compatible computer.   when a windows to go device is started on a new computer, the boot process detects the computer hardware and installs appropriate drivers.   when the same windows to go to start a same computer, then windows to go starts normally automatically by loading the appropriate drivers.   It stores the hardware configurations of multiple computers. Windows to go restriction Windows to go functions in a way that is very similar to a traditional windows 8.1 desktop deployments, but with the following restrictions: ·          In the windows to go default setting sleep and hibernation is disabled.   The functionality can be enabled by configuring group policy but it can lead to data corruption. ·          As


COLOUR AND LIGHTNESS QUALITIES OF DIGITAL IMAGES Friends  in this post i am going to talk about the colors used in digital images or the images we get from digital machines.   So let us start The following terminology is helpful to know when learning about the types of digital images. TONAL RANGE  – It is also called dynamic range.  This term refers  to dark to light ranges or values in an image usually refered to as shadows midtones and highlights.  An image that contains all or most of the possible tones, rather than a smaller portion of the possible tones, Usually appeared  more details and said to have larger tonal range or dynamic range.   Tones may also reffered to as levels or intensities. BRIGHTNESS LIGHTNESS LUMINOSITY LUMINANCE   - These terms refer to dark to light tonal characteristics, as opposed to color characteristics.  They can be thought of as describing the image as if the colors had been converted to blacks grays and whites Hue – it i


MOTHERBOARD AND ITS FORMS The largest and most important circuit board in the computer is the motherboard.   This is also called as the main board or the system board.   The motherboard contains a socket to hold the CPU; the cpu is the component which most processing takes place. The motherboard is the most complicated piece of equipment inside the case because all devices must be communicates with the CPU installed on the motherboard.   All devices in a computer are either installed directly on motherboard or indirectly linked it to by expansion cards.   A device i.e. not installed in the motherboard is called a peripheral device. Now we will discuss something about form factors of motherboard. Form factor refers to the size and layout of motherboards.   As we think not all motherboards are alike.   In fact there is a significant difference in the capabilities and size of different motherboard form factors such as Mini –ITX and ATX.   This topic covers motherboard


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 CP
