Question
2. (a) If an OS is “backwards compatible”, does this mean compatible with old hardware, old device controllers, or something else (what?) (b) Is backwards compatibility done because it is easier to implement in the OS Kernel (or another reason, what)?
3. While PCs and many other computers have a BIOS, Android tablets do not. Does that mean that Android OS is always running, or can it be booted? Can it have a file system?
4. If you run a system Virtual Machine (VM) such as Virtual Box on your computer, can you also run another VM such as the Java VM (JVM)? Why or why not?
Explanation / Answer
Answer)
If an OS is backward compatible then the old features are to be inherited by the newer features and added with some additional features with it. This is mostly meant for object code compatibility. The old executable code will not be changed on the newer products.
Backward compatibility is done as it is efficient to have the older version of the system to work with added features. It will be easy to code and manage the applications.
