Users could go into a Newsgroup, read other people's postings, reply, send e-mail or post something new and start a new thread (topic). To access these Newsgroups, you need a program called a Newsreader, From these beginnings the name UseNet News was coined.

You can use a firewall to enhance your site's security in a number of ways. The most straight- forward is to create an internal site that is accessible only to computers within your own network. From the standpoint of the security of your organization as a whole, the safest place to put it is completely outside the network.

The Class C address is a legal Intemet address, but the 400 addresses you've assigned are not. Will you have to reassign all the IP addresses on your network? No, you have two options; an IP-to-IP gateway of an IPX-to-IP gateway. The IP gateway network-address translation process transparenty remaps all source IP addresses in external outbound connections so a connection's IP address appears to be a legal IP address.
