Java API for XML based Remote Procedure Call (JAX-RPC) uses remote procedure calls using XML messages to communicate in distributed environments.
A Web Service can be used by its service clients deployed on any platform. JAX-RPC service can be used by any Java based or non Java platform. Service Endpoint can be defined . . . → Read More: JAX-RPC
Data Acquisition measures an electrical or physical phenomenon such as voltage, current, temperature, pressure, or sound. Any physical sensor data in analog format can be read and converted into digital format through a Analog to Digital Converter (ADC) card. Because a PC or Computer can accept only digital data. This digital data can be read . . . → Read More: Data Acquisition Systems
As per Christopher Alexander, “Each pattern describes a problem which occurs over and over again in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice” .

JavaBeans are reusable software component models for Java. JavaBeans provide platform neutral component architecture.
Beans vs Libraries Not all useful software modules are necessarily beans Beans are appropriate for software components that can be visually manipulated to achieve some effect. Class libraries are helpful in providing the required functionality for the programmer but they doesn’t . . . → Read More: JavaBeans
JAX-WS is a Java API for creating web services and clients using XML. A web service operation is invoked by an XML-based protocol such as SOAP over HTTP. JAX-WS supports two different service endpoint implementations types, the standard JavaBeans service endpoint interface and a new Provider interface to enable services to work at the XML . . . → Read More: JAX-WS
The Universal Description, Discovery, and Integration (UDDI) is a technology that supports publishing and discovering information about web services. Any consumer application like to use a provider services can search the information provided by that particular web service and integrate with that service for further communication.
UDDI consists two parts.

Servomotors are available as AC or DC motors. Early servomotors were generally DC motors because the only type of control for large currents was through SCRs for many years. As transistors became capable of controlling larger currents and switching the large currents at higher frequencies, the AC servomotor became used more often. Early servomotors were . . . → Read More: Servo Motors
