Routers are also smart devices and know who is on both sides of a connection. Routers also provide network firewall security against hackers in that they are programmed with security protocols. I use an ISDN router now and will switch to a broadband router when the cable and DSL connections are completed. Routers will be standard on most home and small office networks in the future. Server capability Many home and small office networks contain file and print servers.
Servers are computers, whose function is to provide services to users on the network.
File storage containment, print services, remote access, security, and backup are just a few of the services that a server brings to the network. It will only get better in the future. I have had fun speculating about what is in the future. With more time and column space, I could go on about all the stuff to try out. The future looks really bright for computer communication.
