Firewalls are usually placed between the users of a LAN and the Internet (some ISPs also use firewalls) which can be set to screen for incoming viruses and only allow access to certain resources on the Internet as a security measure. It can also accumulate previously visited sites to avoid excessive use of bandwidth.
