4. 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.
5. 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.
