What is Connected Device Configuration (CDC)?

What does CDC stand for?

Connected Device Configuration (CDC) is a fixed of requirements, libraries, and Digital-machine features serving as the basis for Software Programming Interfaces (APIs) focused at customer and embedded gadgets like smart communicators, high cease PDAs, and set-top packing Containers. The CDC helps 3 uNits of APIs referred to as the muse proFile, Private basis profile, and Personal profile.

As part of the Java Platform Micro Edition (Java ME), the CDC is designed for hand held gadgets and Embedded Systems. In specific, it's miles Constructed for devices having higher assets (along with RAM and Storage Memory) than the gadgets supported by means of linked restrained device configuration (CLDC). The CDC can paintings with gadgets driven by way of 32-Bit Microprocessors/Controllers with an available 2 MB RAM and a couple of.5 MB ROM for the Java surroundings.

What Does Connected Device Configuration Mean?

Java ME is supplied to Developers inside the Form of API sets referred to as configurations, profiles, and non-compulsory Packages. A configuration is the largest of those units. It caters to a surprisingly broad Variety of gadgets. Profiles cater to a narrower variety of devices. Optional programs, however, are APIs including Functionality to programs and catering to precise technologies.

The CDC’s three sets of APIs do the subsequent:

1. The foundation profile: For devices with no GUI. It has a J2SE primarily based library and supports several security optional programs, along with the Java Authentication and Authentication Service, Java Secure Socket Extension, and the Java Cryptography Extension.
2. The personal basis profile: Includes basis profile APIs and is for gadgets with light-Weight GUIs. Some summary Windowing toolkit (AWT) lessons are also supported. Applications are primarily based at the Xlet Software Programming version. Developers who write content for Blu-Ray Disks use this profile.
3. The non-Public profile: For high-give up Cell devices and already supports a GUI toolkit based on the AWT. All applications constructed upon this profile are based totally at the applet programming version.

Other non-compulsory applications, which could work on pinnacle of the CDC, consist of:

1. The RMI Optional Package: For dispensed-utility and commUnity communications.
2. The JDBC Optional Package: used for connecting to statistics assets including Spreadsheets, flat documents, and Relational Databases.
