An application programming interface (api) is ________. select one:
a. the code the cpu recognizes to perform a procedure in an application
b. the currently active part of an application
c. the code to interface between an application and a peripheral like a printer
d. the code to interface between an application and ram

In the IT world, when you hear programmers talk about how a certain API in a program is down, what this means is that the code responsible for communication and interaction between software programs is not working. Therefore, an API is a rule/code that interfaces with the underlying CPU in an operating system in order for an application to work. Instead of having snippets of similar code appearing in almost every application out there, the operating system has APIs to which these software applications refer to. Let us just put it this way, APIs are like user interfaces except that they are not meant for human interactions but for machines like software applications
