Designing and Installing a Network

1
Designing and Installing a Network

• Peer to Peer or Server
• Number of workstations vs. Cost
• Administration, distributed or centralized
• Security considerations
• Expansion requirements
• Amount of network traffic

2
Planning for the installation

• Take inventory
• Hardware
• Make, model, RAM, disks, monitor, video, bus
• Software requirements
• Program name, system requirements
• Networking requirements
• Modems, distances, numbers of users, media,
  security

3
Build a Map

• Locate all computers/workstations
• Show what is attached to each
• Calculate cable lengths
• Locate wiring closet possibilities
• Predetermine labor requirements for cable
  installation.

4
Client/Server Computing

• Do we need a centralized service?
• Do we have a database application?
• Do we need to share files?
• What about Calendaring/Scheduling?
• Can we afford the server?
• Can we not afford using a server?

5
Advantages to Server installation

• Administration is centralized
• Maintenance is centralized
• Security is enhanced by the centralization of
  authentication.
• The users take advantage of a more powerful
  computer acting as the server.
• Server systems can be set up to be
  fault-tolerant.

6
Hardware considerations

• NIC (Network Interface Cards)
• Drivers
• Operating System interface
• Troubleshooting
• Conflicts
• Diagnostic lights
• Network accessibility
