The internet is a great place for all ages to learn just about anything. A simple search can take you to places you have never been before. This is the excitement of the internet, but many fear that protection is needed for children. Many software and ISP solutions have been available, but Apple has finally offered something that works.
Most software based filters reside on the individual computer.
Depending on the age the filter is for, these may be counteracted by simple measures such as turning off the filtering extensions or running an uninstall of the program. Also, many filters merely block certain sites or block sites based on a keywords. Neither of these filters are totally effective as blocking some sites leaves many others open. Blocking sites based on keywords is a better way to block sites, in theory, but in practice, this too fails as even using keywords can let some sites through. Another filtering method is based on the ISP that you use to connect to the internet.
