Dry bulb temperature- You take a thermometer and hold it in the room and note the temperature. Its basically the ambient temperature that you see. Wet bulb temperature- Again take same kind of thermometer but this time cover its bulb(shiny part other than glass) by a wet cloth fully. Now note the temperature reading. Conclusion- The rate of evaporation from the wet bandage on the bulb, and the temperature difference between the dry bulb and wet bulb, depends on the humidity of the air.
In computer programming, an application programming interface (API) is a set of routines, protocols, and tools for building software applications.An API expresses a software component in terms of its operations, inputs, outputs, and underlying types.n such languages, the API is still distributed as a library. For example, the Java language libraries include a set of APIs that are provided in the form of the JDK used by the developers to build new Java programs.
For example, Google's YouTube API allows developers to integrate YouTube into their applications by providing the capability to search for videos, retrieve standard feeds, and see related content. Web APIs are used for exchanging information with a website either by receiving or by sending data.
