Answer:
1.<u>Support</u>
In most cases, the simpler the network design, the less technical support you'll require for both installation and maintenance. If you need a complex, high-speed network, consider the level of technical assistance available locally. Many small businesses can't justify the cost of full-time IT personnel. Designing a simple network that can be serviced quickly by local technicians should be a primary consideration. If your business demands a complex network beyond the capabilities of local service, design sufficient redundancy in critical network elements to ensure a minimum level of service until repairs can be made.
2.<u>Expansion</u>
Planning for growth in the initial stages can save future expenditures. The price difference, for example, between a 16-port switch and a 32-port switch can be negligible when compared to the cost of purchasing an new switch to replace one that is too small. Most network devices are designed to provide several years of service.
3.<u>Outside Access</u>
Internet access has become all but mandatory for most modern businesses. It's a good idea to consider the type of Internet connection required and the amount and type of support you will receive from your Internet service provider before designing the rest of your network. Some ISPs will provide support and advice on connection speed requirements and security concerns for commercial accounts before installation.
4.<u>Security</u>
Securing a network from outside intrusion or data theft is a primary concern for many companies. While it is possible to eliminate the expense of Ethernet cabling by opting for a wireless network solution, Wi-Fi networking is the least secure method of sharing data and connections. The encryption methods built into most commercial routers, Wireless Encryption Protocol (WEP), Wireless Protected Access (WPA) and the more recent WPA2, can be cracked by skilled hackers. Designing a network with hard-wired Ethernet connections eliminates the risk of intrusion to only those with physical access to the network.
5.<u>Cost</u>
Equipment and maintenance costs are often the first consideration in network design. Fortunately, the cost of hubs, routers and switches are relatively low when compared to the early days of networking.
