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

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

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.

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?

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.

Hardware considerations NIC (Network Interface Cards) Drivers Operating System interface Troubleshooting –Conflicts –Diagnostic lights –Network accessibility
