Network segment

From Free net encyclopedia

A network segment is a portion of a computer network separated by a computer networking device, including:

• Repeater or Ethernet hub (both OSI layer 1 devices)

• Router (OSI layer 3 device)

A bridge separates collision domains while a router separates both collision domains and broadcast domains.Template:Compu-network-stub
