Hardware such as routers, hubs, switches, servers, ports, cabling, client computers and phones is identified. Network system integrators begin to install the network operating systems (NOS). These may be vendor-specific solutions or include heterogeneous systems designed to work in tandem and communicate with each other. Once the hardware and software is in place, system integration activities are turned over to network administrators and managers. These individuals provide network management services that include implementation and maintenance. Using a variety of software applications, network system integrators who specialize in administering networks can monitor traffic, detect and prevent security leaks, tune network databases, and enhance network performance. Specifically, these activities include testing network connectivity, enabling file and printer sharing, implementing backup and storage solutions, monitoring external devices, centralizing control using server audits, load balancing and user control.
