A special browser or filtering program designed to reject websites not suited for children. Such programs may screen pages by word content, site rating or by URL, using an updated database of objectionable sites, or any combination of these techniques. Parental control software is also built into Windows and Mac computers, as well as smartphones and tablets. However, third-party apps are also available that can offer more flexibility. See PICS

For children who spend too much time on a Windows computer, parents can set up a separate account for each child and allow or block every hour of the week. If the computer is used when a blocked hour is reached, all access to that account is shut off.
