Which connection type is best for you?

Your specific needs determine the best connection - serial, modem or network. Although trends favor networking, it has some disadvantages. Networking's biggest disadvantage is cost. Installing a network, especially a wide-area network (WAN), is costly and complex. Networking costs require that many companies install networks gradually. These companies end up with dual communication needs requiring dual solutions. Ongoing network maintenance is expensive and generally beyond the capability of most users. Networking may mean hiring a system administrator, contracting with one, or investing in additional training for your current administrator.
