           Pixel

A Pixel or a picture image is a physical in a raster image which in computer graphics is a dot matrix data structure representing a generally rectangular grid of pixels,or the smallest addressable element in an all points addressable display device.
      Colour Models – RGB and CMYKRGB and CMYK 

The RGB colour model is an additive colour model in which red, green, and blue light are added together in various ways to reproduce a broad array of colours. The name of the model comes from the initials of the three additive primary colours, red, green, and blue.
The CMYK colour model is a subtractive colour model, used in colour printing, and is also used to describe the printing process itself. CMYK refers to the four inks used in some colour printing: cyan,magenta, yellow, and key which is black. Though it varies by print house, press operator, press manufacturer, and press run, ink is typically applied in the order of the abbreviation.

   Resolution
       having a high resolution can be great but only if you have the software to keep up with it for example on if you have a 50 inch television and sit close to it the screen will seem pix-elated but if you sit an appropriate distance away the picture quality will be better.

        Raster Images: file formats and uses - psd, bmp, gif, tiff, jpg, png

A raster image, also called a bitmap, is a way to represent digital images. It can be created in a wide variety of formats, including the familiar .gif, .jpg, and .bmp. The image is represented in a series of bits of information that translate into pixels on the screen. These pixels form points of colour that create an overall finished image.When a raster image is created, the image on the screen is converted into pixels. Each pixel is assigned a specific value that determines its colour. This format uses the red, green, blue (RGB) colour system.

psd - means,photo shop,Adobe Photo shop is a raster graphics editor developed and published by Adobe Systems for Windows and OS X.Photo shop was created in 1988 by Thomas and John Knoll. Since then, it has become the de facto industry standard in raster graphics editing, such that the terms "photo shopping" and "photo shop contest" were born. It can edit and compose raster images in multiple layers and supports masks, alpha com positing and several colour models including RGB, CMYK, Lab colour space (with capital L), spot colour and duotone.

bmp - means,Bitmap,In computing, a bitmap is a mapping from some domain (for example, a range of integers) to bits, that is, values which are zero or one. It is also called a bit array orbitmap index.In computer graphics, when the domain is a rectangle (indexed by two coordinates) a bitmap gives a way to store a binary image, that is, an image in which each pixel is either black or white (or any two colours).

.

GIF - stands for "graphics interchange format," and is one of the oldest image types used online. In fact, the first image ever uploaded to what we now know as the World Wide Web (once just a small network of computers in a Swiss lab) was a GIF.

 tiff -means,tagged image file format,TIFF is a computer file format for storing raster graphics images, popular among graphic artists, the publishing industry,and both amateur and professional photographers in general.

jpg- means,Gif, jpg and PNG files are all three used for the web. The difference is the resulting image. Each one has its place for use on websites, and jpeg images can also be used in print files as well, although they need to be print resolution.

Vector Images: file formats and uses - Vector graphics is the use of geometrical primitives such as points, lines, curves, and shapes or polygons—all of which are based on mathematical expressions—to represent images in computer graphics

eps,Encapsulated PostScript -(EPS) is a DSC-conforming PostScript document with additional restrictions which is intended to be usable as a graphics file format. In other words, EPS files are more-or-less self-contained, reasonably predictable PostScript documents that describe an image or drawing and can be placed within another PostScript document.

 wmf,Windows Metafile- (WMF) is an image file format originally designed for Microsoft Windows in the 1990s. Windows Metafiles are intended to be portable between applications and may contain both vector graphics and bitmap components.

        fla,Files that contain the.fla file extension are files that are used by the adobe flash application.When you create a new Flash file in the Macromedia Flash authoring program, you create an FLA file. This contains all the elements which make up the finished product, including graphics, animation instructions, actionscript code, comments, etc. FLA files can only be opened in Flash (not the Flash Player).

         svg,Scalable Vector Graphics- (SVG) is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation. The SVG specification is an open standard developed by the World Wide Web Consortium (W3C) since 1999. SVG images and their behaviors are defined in XML text files

        Cross-platform Images: format and uses -,In computing, cross-platform, or multi-platform, is an attribute conferred to computer software or computing methods and concepts that are implemented and inter-operate on multiple computer platforms.PDF-Portable Document Format (PDF) is a file format used to present documents in a manner independent of application software, hardware, and operating systems.

      Compression - The type of compression we've been discussing here is called lossless compression, because it lets you recreate the original file exactly. All lossless compression is based on the idea of breaking a file into a "smaller" form for transmission or storage and then putting it back together on the other end so it can be used again.

      A Lossy -compression works very differently. These programs simply eliminate "unnecessary" bits of information, tailoring the file so that it is smaller. This type of compression is used a lot for reducing the file size of bitmap pictures, which tend to be fairly bulky. To see how this works, let's consider how your computer might compress a scanned photograph.

      A lossless -compression program can't do much with this type of file. While large parts of the picture may look the same -- the whole sky is blue, for example -- most of the individual pixels are a little bit different. To make this picture smaller without compromising the resolution, you have to change the color value for certain pixels. If the picture had a lot of blue sky, the program would pick one color of blue that could be used for every pixel. Then, the program rewrites the file so that the value for every sky pixel refers back to this information. If the compression scheme works well, you won't notice the change, but the file size will be significantly reduced.
     
       Image Capture Devices –  An image capture device eg:a camera a device for recording visual images in the form of photographs or films.

       
        scanner-In computing, an image scanner often abbreviated to just scanner, although the term is ambiguous out of context is a device that optically scans images, printed text, handwriting, or an object, and converts it to a digital image. Commonly used in offices are variations of the desktop flatbed scanner where the document is placed on a glass window for scanning.

        digital camera-A digital camera is a camera that encodes digital images and videos digitally and stores them for later reproduction.Most cameras sold today are digital,and digital cameras are incorporated into many devices ranging from PDAs and mobile phones (called camera phones) to vehicles.

        tablet-A tablet computer, or simply tablet, is a mobile computer with display, circuitry and battery in a single unit. Tablets are equipped with sensors, including cameras, microphone, accelerometer and touchscreen, with finger or stylus gestures replacing computer mouse and keyboard.

       smart phone-A camera phone is a mobile phone which is able to capture photographs and high-definition video. Since early in the 21st century the majority of mobile phones in use are camera phones.

      Optimizing-In computer science, program optimization or software optimization is the process of modifying a software system to make some aspect of it work more efficiently or use fewer resources. In general, a computer program may be optimized so that it executes more rapidly, or is capable of operating with less memory storage or other resources, or draw less power.
      
      Storage and Asset Management- didital asset management (DAM) consists of management tasks and decisions surrounding the ingestion, annotation, cataloguing, storage, retrieval and distribution of digital assets.
