Multimedia Hardware Categories of Peripheral Equipments: Platforms and Processors – aspects of personal computer that affect the development and delivery of multimedia applications.Input Devices – there are a wide variety of ways of interacting with multimedia applications. Multimedia Storage – the high storage demands of multimedia materials require careful estimation and consideration of storage media. Multimedia Connections – speed of presentation will depend on the appropriate connection between devices.

The multimedia platform – the equipment on which multimedia is developed or played – needs a very comprehensive description because it covers not only the processor and operating system but also screen resolution, bit depth and sound, amount of memory and the size of the hard disk storage.
The platform should be precisely defined in terms of the version of operating system, what multimedia facilities are supported, its interaction devices (such as mouse or touch screen) and ancillary devices such as CD-ROM.
Other details include: Type and speed of processor
Size of hard disk storage
Speed of CD-ROM size
Connection to networks, both local areas as well as wide area and Internet Screen resolution
Number of colors supported
Sound card features (8-bit, 16-bit etc.)
Video compression facilities (AVG, MPEG etc.)
Scanners are particularly useful in the development o multimedia as they convert existing artwork such as cartoons and photographs into electronic images and avoid the need to create original images.
Most multimedia is presented on color monitors that display a matrix of 640 pixels wide and 480 pixels high with 256 colors for each pixel
This is called VGA (Video Graphics Array) and is sufficient to display good photo-realistic images.
Touch screens
There are two main touch screen technologies:
The screen is covered with a textured coating that is sensitive to pressure and registers the location of the user’s finger when it touches the screen
Keyboards
Although it is possible to enter text by touching and onscreen representation of the keyboard, physical keyboard still represent the most efficient way of entering details such as name and address.
Keyboard facilities are essential for multimedia development. Multimedia makes no special demands for keyboards
