Monitoring Software
This software is mostly useful when you have children who will be using a computer to access the internet. The software works in one of four ways - white list (only those web sites listed can be accessed - useful for small children where you decide in advance what web sites that they can visit), blacklist (a list of web sites that can't be accessed - ineffective because there will be lots of similar sites that are not blocked), algorithmic (where the software determineds whether or not to allow access based on the content of the page - more effective than blacklist but will still let lots of sites that ought to be blocked thriugh as well as blocking access to legitimate sites), logging (record whe sites that are visited in a log - useful with older children as you can see what sites that they have visited).
