The net is a network of computers from around the world. The network uses a common protocol, so that computers of whatever type may read each other s information.
People connect to the net via a university, their work or a service provider.
For example, there are legal mailing lists which provide updated legal material to people on the lists. Mailing lists may also be used by a group of people who want to talk to each other and discuss issues. File transfer may be conducted over the net. The procedure is the same as copying a floppy disk onto your hard drive. There are an extremely large number of these groups on the net.
