Suppose you have a class Ship, which was written by another programmer who used to work for your employer. Ship is used in several different applications. Ship contains a public method called getBearing() that consults gyroscopes and a compass to determine the direction in which the ship is moving and returns a Location object. You need to refactor the code to use a GPS receiver instead. You should

Research of the GPS features and the modules and packages needed by the programming language to implement and receive data from a GPS tracker.

Explanation:

The Ship class is a blueprint that holds a data structure of a ship's location in coordinates. The location variable can be changed using the getBearing method and an instance of the ship class can be made several times for different ships in the harbor. This class depicts the power of object-oriented programming.

Refactoring is a concept in software engineering where source codes are modified to achieve code efficiency and speed. All programming language source code should be refactored where needed with the right packages or modules.

answer; insolated i/o uses separate memory space,and on the other hand memory mapped i/o uses memory from the main

i think the answer is b. sql.
