    7. 7. Hub and Switches Device General Characteristics General Use Hub All ports share single signal Home - Obsolete Switch Each port has its own signaling Home/small network Layer 2 Switch Switch, Plus simple management tagging Where you need network separation Vlans – I.E. Accounting, staff Layer 3 Switch Layer 2 Switch, Plus Routing Where you need communication between Vlans – IE VoIP, Security
