Everything About API You Should Know

Application Program Interface or simply known as API is a set of protocols, routines as well as tools required to build software applications. API specifies how the software components would interact to each and in addition, it’s used as well when programming components for GUIs or Graphical User Interface. Truth is, a good API makes it less challenging to make a program by providing the building blocks which are put together by the programmer.

There are different types of APIs and these are widely used nowadays for applications, websites or even operating systems. As an example, Windows makes use of different API sets that are being used by system applications as well as hardware and when copying and pasting text from one app to the other, basically it is the API that does the work.

A GUI makes it easier for people to use programs. Application programming interfaces make life simpler for developers to use some technologies to build applications. The API helps to reduce the cognitive load on the part of the programmer by exposing actions or objects that the developer needs and abstracting the underlying implementation.
A Quick Overlook of Software – Your Cheatsheet

While graphic interface for email client might provide users with a button that can perform all steps to highlight and fetch new emails, API for file input and output gives developers the function to copy a file from one place to another without having to understand the file system operation that occurs behind the scenes.
Doing Companies The Right Way

As what said earlier, APIs have different uses and purposes so it is not really surprising if there are APIs on frameworks and libraries, operating systems, web and in fact, there are API for SEO as well. Believe it or not, some of the more popular uses of APIs are in Google Maps and YouTube. In regards to Google Maps for example, the APIs make it possible for developers to embed Google Maps on the website by making use of Flash interface or JavaScript while in YouTube, it allows videos and functionality of the site to be integrated to apps or websites. This is basically one of the reason why it is possible for us to play and watch live stream YouTube videos even if we are not directly on the site because YouTube has live streaming API, YouTube Player API and many more.

In fact, the way the API is created has a big effect on its usability. With this being said, the design of API is trying to provide only the tools that a user expects from it. As a matter of fact, the design of programming interface is a vital part of any software architecture which is basically the organization of complex piece of software.
