Network Diagram - Case 1

CASE 1

The company own just one printer, a moderately priced ink-jet printer that’s connected to Erin’s computer. The computers aren’t networked, so whenever Mark, Julie or Daniel need to print something, they must copy file to a diskette and give it to Erin, who then prints the document. The computer shared by Mark and Julie connected to the Internet via a residential DSL connection.

The company wants to install a network to support these three computers. Here are the primary goals of the network

• Provide shared access to the printer so that users don’t have to exchange diskettes to print their documents
• Provide shared access to the Internet connection so that users can access the Internet from any of the computers.
• Allow for the addition of another desktop computer, which the company expects to purchase within the next six months, and potentially another notebook computer. (If business is good, the company hopes to hire another engineer)
• The network should be intuitive to the users and should not require any extensive upkeep.

CSS’s networking needs be met with the simple peer-to-peer network diagrammed. Here’s what the network requires:

• A 10/100Mbos Ethernet adapter card for the gateway computer, which is the only computer that doesn’t currently have a network port.
• A combination of DSL router and four-port 10/100Mbps switch, such as the LinkSys BEFSR41W or the Belkin F5D5231-4. The company may outgrow this device when it adds an additional laptop, but if and when that happens, another 4-or 8-port 10/100Mbps switch can be added then.
• The firewall features of the DSL router will need to be enabled to protect the network form Internet hackers
• File and printer sharing will need to be activated on Erin’s computer and the printer will need to be shared.
