9. Business Applications Home Applications Mobile Users Social Issues
Networking
Point to point communication not usually practical
Devices are too far apart
Large set of devices would need impractical number of connections
Solution is a communications network
Wide Area Network (WAN)
Local Area Network (LAN)
A network with two clients and one server.
Home Network Applications
Access to remote information
Person-to-person communication
Interactive entertainment
Electronic commerce
Home Network Applications (2)
In peer-to-peer system there are no fixed clients and servers.
