So you've just bought your children a computer with all the fancy attachments, and you are excited because now they have a real learning tool in the house, besides the "tube." Your children will be able to access the Internet to look up answers to homework questions, or research for school papers.

But unfortunately, like television, there are things on the Internet that may not be appropriate for the eyes of youngsters.

So what do you do to prevent your child from looking at sites beyond their years? Parents can take two approaches to this matter: buy blocking software or supervise your child along the online roadway.

Option One

Several companies have created filtering software, programs that come with pre-site blocks related mainly to sex, sexuality and drug use along with other items deemed offensive -- such as hate and cruel speech. Basically, once you plug in the software, your child can't visit these sites.

Parents beware, though: This blocking software has potential drawbacks. Objectionable Web sites pop up every day that haven't been run through the filter. Also, this software doesn't prevent children from entering adult-oriented discussion areas, commonly referred to as "chat rooms."

Critics say that this software also blocks out useful and appropriate information, for instance a news-oriented Web site with a report on breast cancer may be deemed inappropriate, and therefore, inaccessible.

The largest filtering software is available for download from the Web on a trial basis, with purchase required after a certain number of days. You can also buy it at most computer stores.

Here are four popular 'Net filters available online:

• Net-nanny
• CYBERsitter
• Surfwatch
• Cyberpatrol

Option Two

Go surfing with your children. Show kids good surfing habits, like you would with your television set. Software or hardware cannot replace the watchful eye of a parent or guardian. Here are a few good places where you can start.
