Welcome to the world of networking with 3Com

®

. In the modern

business environment, communication and sharing information is crucial.

Computer networks have proved to be one of the fastest modes of

communication but, until recently, only large businesses could afford the

networking advantage. The OfficeConnect

®

product range from 3Com

has changed all this, bringing networks to the small office.

The products that compose the OfficeConnect range give you, the small

office user, the same power, flexibility, and protection that has been

available only to large corporations. Now, you can network the

computers in your office, connect them all to a single Internet outlet, and

harness the combined power of all of your computers.

Router

The OfficeConnect Wireless 54Mbps/108Mbps 11g cable/DSL Router is

designed to provide a cost-effective means of sharing a single broadband

Internet connection amongst several wired and wireless computers. The

Router also provides protection in the form of an electronic “firewall”,

preventing anyone outside of your network from seeing your files or

damaging your computers. The Router can also prevent your users from

accessing Web sites which you find unsuitable.

Figure 1

shows an example network without a Router. In this network,

only one computer is connected to the Internet. This computer must

always be powered on for the other computers on the network to access

the Internet.

When you use the Router in your network (

Figure 2

), it becomes your

connection to the Internet. Connections can be made directly to the

Router, or to an OfficeConnect Switch or Hub, expanding the number of

computers you can have in your network.
