API stands for ‘Application Programming Interface’ and this allows people to create applications that can access the features or data of operating systems, apps or services. Google Maps API is supported on many platforms, operating systems and the web. This allows apps and websites to be able to use google maps in their system. A great example of this is that a business can use this to display a map with their business location to make it easier to find for customers.
To demonstrate, I have used my home from the NT and you are now able to view google maps.
