The Charging System The charging system provides the electrical energy required by the various electrical systems and also keeps the battery charged. Types of charging systems 1. Dynamo This was the type of electrical generator used on older vehicles. It consisted of a rotating conductor inside a fixed magnetic field. Rectification of the A.C. current to D.C. was by means of a commuter. Output of the dynamo was limited due to the rotating speed of the conductor 2. Alternator In the alternator

Cloud storage is a model of networked online storage where data is stored on multiple virtual servers‚ generally hosted by third parties‚ rather than being hosted on dedicated servers.Hosting companies operate large data centers; and people who require their data to be hosted buy or lease storage capacity from them and use it for their storage needs. The data centeroperators‚ in the background‚ virtualize the resources according to the requirements of the customer and expose them as storage pools

System Concepts for Data Modeling Crystal M. Reedus CIS 210 November 21‚ 2010 Abstract Data modeling techniques and methodologies are used to model data in a standard‚ consistent‚ predictable manner in order to manage it as a resource. Data models support data and computer systems by providing the definition and format of data. From a modeling perspective‚ the entire problem domain is viewed as a collection of class hierarchies (of objects) that are connected by messages. Data modeling
