There are various ways in which computers can be networked together. Some computer networks (such as computer labs) configure their workstations for '''static IP addresses for security and to provide other interesting features such as WOL''' (Wake Up on Lan) which allows a signal from a computer system to remotely start all or specified workstations within the lab. '''Hot-spots (such as cafes or airport lounges) offer the ability for users to connect to the Internet (via DHCP) from their mobile devices''' (such as notebooks, netbooks, tablets, or smart phones). Finally , there are '''hybrid solutions that may offer both fixed IP address (computer workstations) and allow for wireless connect connections (via DHCP) to a smart-phonemobile devices''' (like at your Seneca computer labs).
