A software server is a commercial software environment, which contains a set of applications and which can be deployed to a hardware server. A hardware server is a device that serves data or other support to network devices and which usually has higher specifications than client devices. A workstation is a client machine to which an application or a server can be deployed. A mobile device is a portable client used remotely to access the network. Network nodes represent other type of network objects (routers, switches, firewalls, modems, printers, faxes, etc).
