API. the complete set of operting system functions that an application program can use to perform tasks such as managing files and displaying information on the computer screen. An API is a complete definition of all the operating system functions available to an application program, and it also describes how the application program should use those functions. In operating systems that support a graphical user interface, the API also defines functions to support windows, icons, pull-down menus, and other components of the interface. In network operating systems, an API defines a standard method application programs can use to take advantage of all the network features.
The set of standards and protocols by which a software application can be accessed by other software. Used for communication between application programs. The application program interface must exist before a program can be called by an external program and before it can send a response to an external program.
An API is simply a collection of functions and data types a program uses to access some service. The data types and functions defined in stdio.h, such as printf(), fseek(), FILE, and fputc(), constitute a commonly used API for C program I/O. The advantage of an API is that it insulates the user from the implentation details of the program.
A protocol boundary between an application program and a computer control program. The CallPath Enterprise API consists of program calls that an application program can invoke and a set of event messages that an application program can request the CallPath Enterprise Server to send to it.
An software interface that allows your application to access another application or web service. A client may have an API connection to load database information to an email vendor automatically and receive data back from the email. Google, Amazon and eBay all provide an API interface for web developers to write applications that interface directly with their service.
The interface between the subscriber unit and the multiple application subsystem. Generally consists of simple commands such as "open a connection." These commands are translated by the enabling layer into commands that either control the network connection or communicate data across the network.
Generic term for any language and format used by one program to help it communicate with another program. Specifically, an imaging vendor can provide an API that enables programmers to repackage or recombine parts of the vendor’s imaging system, or integrate the imaging systems with other applications, or to customize the user interface to the imaging system.
A set of public programmatic interfaces that consist of a language and message format to communicate with an operating system or other programmatic environment, such as databases, Web servers, JVMs, and so forth. These messages typically call functions and methods available for application development.
A set of routines, protocols, and tools for building software applications, which provides all the building blocks for the programmer to put together. Most operating environments, such as MS-Windows, provide an API so that programmers can write applications consistent with the operating environment. Although APIs are designed for programmers, they are ultimately good for users as their similar interfaces make it easier for users to learn new programs.
A specific method prescribed by a computer operating system or by an application program by which a programmer writing an application program can make requests of the operating system or another application.
APIs are sets of routines, protocols, and tools for building software applications. A good API makes it easier to develop a program by providing all the building blocks. A programmer puts the blocks together. Most operating environments, such as Windows, provide an API so that programmers can write applications consistent with the operating environment. Although APIs are designed for programmers, they are ultimately good for users because they guarantee that all programs using a common API will have similar interfaces. This makes it easier for users to learn new programs.
This term describes an organized method for arranging communications between multiple computer programs or between multiple modules of a single program. Usually an API is either based on a standard file exchange method or a collection (library) of different functions.
(1.) A set of run-time routines or system calls that allows an application program to use a particular service provided by either the operating system or another licensed program. (2.) The formally defined programming language interface that is between a system control program or a licensed program and the user of the program.
A protocol boundary between an application program and a computer control program. The CallPath Services API consists of program calls that an application program can invoke in order to request functions be performed by the CallPath Services subsystem component of the computer or by a telephone switch. The API also consists of messages that the program can request be sent to it by the switch or by the CallPath Services subsystem.
An application program interface is an implementation of a Service Access Point (SAP) or collection of SAPs?. A set of standard software interrupts, calls, functions, and data formats that can be used by an application program to access network services, devices, or operating systems.
The interface (calling conventions) by which an application program accesses operating systems and other services. An API provides a means for developing custom user interfaces. The web API provides a programmable interface to the GeoConnections Discovery Portal.
an encapsulation of functionalities common to many applications into reusable modules. This encapsulation provides consistency among applications, as well as a reduction in complexity for access of data.
