What Is Api ? |
|
Answer» An Application Programming INTERFACE (API) is a set of classes that you can use in your own application.

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.
