Question$1$ : Computer component

You are writing a diagnostic utility to test the various components of a computer system to ensure that they will work with your big, expensive enterprise application. You want to write one class for each computer component you diagnose: CPUTest, MemoryTest, and DiskTest. However, your utility needs to be cross$-$platform, and each class contains some platform$-$specific code. So for each type of test, you will have several implementations, one for each platform: PCMemoryTest, MacMemoryTest, LinuxMemoryTest, etc. You$$d like your diagnostic utility to create and use the right test classes for the platform its running on$,$ without having to change a lot of code each time you add a new platform. You recall that there is a design pattern to solve this problem.

What design pattern would you use?

Draw a UML class diagram showing the relationships among participants in your design pattern.
