"API calls" have no specific question; the term APIsimply means application programming interface, and to call an API simply means to invoke a function (or subroutine) from a computer program.
Each API call is different in how it is called (e.g. does it require any parameters, and of so, which), when (e.g. can it be called at any time and under all circumstances), what it does and what it returns to the caller.
API functions serving closely related purposes are often grouped together into an API.
Take this hypothetical example: One API provides services for rounding numbers: one function of this API rounds numbers to the nearest whole number, another function that belongs to the same API rounds numbers to the nearest hundredth.
The purpose of API is unlimited. Examples of API include API to allocate, manage and return memory from a heap, API to create, manage and delete files and folders on a hard disk, API to get and set the current time, API to draw lines and other geometric shapes, etc, etc.

Why use api's rather than system calls?
System calls are platform-dependent, while using abstracted APIs allows your programs to run on multiple platforms, which is a primary benefit of Java. You should minimize the use of system calls when possible, because those will not be portable across platforms.
Why you use API rather than System Calls?
System calls are much slower than APIs (library calls) since for each system call, a context switch has to occur to load the OS (which then serves the system call).

What is API?
API is an Application Programming Interface.It is an interface that defines the ways by which an application program may request services from libraries and/or operating systems.An API determines the vocabulary and calling conventions the programmer should employ to use the services. It may include specifications for routines, data structures, object classes, and protocols used to communicate between the requesting software and the library.An API itself is largely abstract in that it specifies an interface and controls the behavior of the objects specified in that interface. The software that provides the functionality described by an API is said to be an implementation of the API. An API is typically defined in terms of the programming language used to build the application.The API initialism may sometimes be used as a reference, not only to the full interface, but also to one function, or even a set of multiple APIs provided by an organization. Thus, the scope of meaning is usually determined by the person or document that communicates the information.
Why do you prefer using API over system call to execute services or routines of operating system?
simplicity & portability, especially if POSIX API is used as many totally different OSs support this API. using native OS calls would result in nonportable code.

How does rootkit running in user mode normally hide?
A+ pg. 1052: A rootkit running in user mode intercepts the API calls between the time when the API retrieves the data and when it is displayed in a window.
What is jdbc-odbc bridge?
jdbc-odbc bridge is a jdbc driver required to connect java application to the specified database. Using this driver the java calls are converted to the odbc calls and then are referred to the database. Since odbc driver are the implemetation of the API written in C language. As in the case of this driver the API is provided by Sun MicroSystem itself and the implementation of these API is done by the Database Vendors.
Why you use API rather than System Calls?

What do you mean by API in software testing?
API is an acronym for Application Programming Interface. API testing is a collection of application's methods and procedures, called API calls. Here, we send these API calls to get output and note down the system's response. These responses from these calls are used to validate any test scenario. In order to test an API, functional testing services perform API testing using any testing tool such as POSTMAN, SOAP UI, Parasoft and HP QTP.As Most applications are segregated in 3 distinct layers:1. Presentation layer2. Business layer3. Database layerAPI testing provides communication and data exchange between two distinct software systems. It communicates with the business and database layers to confirm the correctness of a test.Where as GUI testing is performed in the presentation layer. In API testing, we won't concentrate on the outlook and experience of an application.Types of APIs :1. SOAP: Simple Object Access ProtocolIt is language and platform independent. It supports built-in error handling feature. It uses XML file to provide messaging service.2. REST: Representational State TransferREST is easy to understand alternative to SOAP. With the help of REST, we can generate multiple formats, such as CSV, JSON or RSS, which are faster as compared to SOAP.Common commands for REST API are:* POST - used to create new records.* GET - used to read existing data..* PUT - used to update existing records.* DELETE - used to delete data.

How do I find my API key?
The API key is used for accessing the application program interface. There are various functions that can be performed using the API key. The key should be kept confidential and hence, it should be saved in a safe place. The API key can be found in the “Api Access” area of the control panel.
