1. Memory Management Activity

2. Windows Memory Microsoft Windows on a desktop uses virtual memory
The system is designed to run many large programs
Programs can be terminated when they are done

3. Android Memory Android does not use virtual memory
The entire program is loaded before execution starts
Android strictly limits the maximum size and amount of CPU time an app can use
When you are done using an app, it remains in memory available if you want to use it again

4. Visible Differences
The different systems behave differently when presented with a heavy load
Windows will always run the programs even if the system bogs down
Android will not allow programs to monopolize the CPU
If Android runs low on memory, it will kill low activity apps

5. Hands-On Activity
Go to williams.comp.ncat.edu/ MobileOS/MemActivity.html
Download and uncompress the Zip file
Run the MemTest program
Look in memDataMemoryResults.txt to see the results of the experiment
What does it all mean?
