When a switch receives a frame it examines the target MAC address to determine if the frame should be passed to a specific port or blocked. If it is a unicast address it will be switched to only the port on which that specified device resides. If it is a broadcast (ff ff ff ff ff ff) it will be forwarded to all ports. The most common way to "bound in" broadcast domains is through the use of routers or VLANS.
