CLOUD COMPUTING Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the internet). PUBLIC CLOUD Public cloud is one based on the standard cloud computing model, in which a service provider makes resources, such as applications and storage, available to the general public over the internet. Public cloud service may be free or offered on a pay per usage model. PRIVATE CLOUD Private cloud (also called internal cloud or corporate cloud) is a marketing term for a proprietary computing architecture that provides hosted services to a limited number of people behind a firewall. A COMMUNITY CLOUD A community cloud is a multi- tenant infrastructure that is shared among several organizations group with common computing concerns There are also the most distinctive features of Cloud Computing: In order to approach the architecture of cloud computing, one can imagine a simple Calculator. Processor cor...

Upload The process of transferring information from a computer to a web site (or other remote location on a network). To transfer information from a computer to a web site (or other remote location on a network). URL Uniform Resource Locator. The protocol for identifying a document on the Web.

3D Computer Graphics In the 2D system, we use only two coordinates X and Y but in 3D, an extra coordinate Z is added. 3D graphics techniques and their application are fundamental to the entertainment, games, and computer-aided design industries. It is a continuing area of research in scientific visualization. Furthermore, 3D graphics components are now a part of almost every personal computer and, although traditionally intended for graphics-intensive software such as games, they are increasingly being used by other applications. Parallel Projection Parallel projection discards z-coordinate and parallel lines from each vertex on the object are extended until they intersect the view plane. In parallel projection, we specify a direction of projection instead of center of projection. In parallel projection, the distance from the center of projection to project plane is infinite. In this type of projection, we connect the projected vertices by line segments which ...
