In microbiology, the minimum inhibitory concentration (MIC) is the lowest concentration of a chemical which prevents visible growth of a bacterium. This is in difference to the minimum bactericidal concentration (MBC) which is the concentration resulting in microbial death as defined by the inability to re-culture bacteria.
What is iTunes Home Sharing? iTunes home sharing is a new way of conveniently sharing content on your gadget between five computers around. It enables you to stream photos, music, and videos among different computers.
If they are using your ID, any photos they take will end up on your device too. With their own IDs, this will not happen unless you specifically set it up to do so. If you all sync to different computers iTunes Home Sharing can be used to keep purchased content in sync. Just authorize each computer using your AppleID. One caveat: Make sure that neither your wife or son use their own AppleID for purchases, or only they will be able to see the app.
