The function of a router is to switch and filter packets, and to route traffic between different networks, thereby reducing the size of "collision zones". Broadcast zones are basically all that define a network. Therefore, if a router were to forward broadcasts, it would actually be joining the two networks together into one larger network, which, aside from security implications, would create a giant collision zone and reduce network performance.
The broadcast will be received by all devices in the same network, but will not be forwarded outside the network (routers do not forward broadcast messages). So for the Internet, for example, you do not see broadcast packets.
Limited Broadcast - Sent to all NICs on the some network segment as the source NIC. It is represented with the 255.255.255.255 TCP/IP address. This broadcast is not forwarded by routers so will only appear on one network segment.Direct broadcast - Sent to all hosts on a network. Routers may be configured to forward directed broadcasts on large networks. For network 192.168.0.0, the broadcast is 192.168.255.255.
Generally speaking, routers will unicast-forward incoming packets which have a network broadcast address as destination, unless they are directly connected to that network/subnet and therefore know that the destination address is a broadcast address
On shared-media networks (i.e. hubs or pure ethernets), routers break up broadcast domains and bridges break up collision domains. Routers also break up collision domains. On switched networks, routers break up broadcast domains, and every switch port is its own separate collision domain.
Depending on the router, yes, a Mac and a PC can get internet on the same Wi-Fi. Some old routers can only broadcast to one unit. Newer routers these days can broadcast to 4 units.
AnswerYes. You can't split a broadcast domain without also splitting the collision domain. The only devices that can split a broadcast domain are routers and layer 3 switches. Switches, bridges, and routers can all be used to split the collision domain. Hubs and repeaters do not split the collision domain or the broadcast domain.
It's because of collision and broadcast domains. Routers allow to break both.
The exact method to disable the broadcast of your SSID will vary depending on your router. Most routers have an option directly within the settings which will allow you the option to mask the broadcast of your SSID.
Yes, routers can break up collision and broadcast domains.
No routers dont.
switch
SwitchDescription: Network Switch a device that seperates the Broadcast domain of a LAN segment from other segments.
