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

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
