Bill Gates puts restrictions on his daughter's computer time. That's right. Just because she is the daughter of Bill Gates does not mean that she gets all the time in the world to play on her computer. Yes, Gates and his wife Melinda sets a limit of 45 minutes a day on weekdays and an hour a day on weekends for games that their 10 year old daughter can play on the computer. Parental supervision is a must for all children using the computer. It is always advisable not to keep the computer in the children's room. It should be kept in an area where elders of the family have easy access. Furthermore, see to it that the computer monitor screen does not face the wall but it should face towards the inside of the room so that all can have an open view. In such a scenario it will be impossible for kids to hoodwink parents and visit unwanted sites. Windows Vista OS is a boon for parents as they can not only control the sites that their kids see but also has an audit log that shows the sites they have visited and whom they have been Instant Messaging.
