What is API
An Application Programming Interface (API) is a set of
classes that you can use in your own application. Sometimes
called
libraries or modules, APIs enable you to write an application
without reinventing common pieces of code. For example, a
networking API is something your application can use to make
network connections, without your ever having to understand the
underlying code.
What is AMPS
Advanced Mobile Phone Service (AMPS) is a first-generation
analog, circuit-switched cellular phone network. Originally
operating in the 800 MHz band, service was later expanded to
include transmissions in the 1900 MHz band, the VHF range in
which most wireless carriers operate. Because AMPS uses analog
signals, it cannot transmit digital signals and cannot
transport data packets without assistance from newer
technologies such as TDMA and CDMA.
What is CDC
The Connected Device Configuration (CDC) is a specification
for a J2ME configuration. Conceptually, CDC deals with devices
with more memory and processing power than CLDC; it is for
devices with an always-on network connection and a minimum of 2
MB
of memory available for the Java system.
