A router is a device that routes all traffic to and from your network. A router functions by forwarding packets of data between computer networks.
This device is called a ROUTER. Routers are by default configured to not pass the broadcast traffic to another networks to which it connects. But by some means it could be also a SWITCH - sometimes it can be configured to filter different type of network traffic.

In computer networking, a device on a LAN (local area network) is only supposed to (and expected to) receive and respond to packet messages directed to that devices address. In promiscuous mode, the device will receive and maybe process packets that were directed to other device addresses as well. Promiscuous mode can be used to study network traffic and monitor for unauthorized devices. In early networks, all traffic propagated to every device on the network and each device such as a computer or printer only paid attention to traffic intended for it and ignored the rest. This was a result of all devices attaching to different parts of the same cable (10Base2 for the technically aware) or because a device called a "hub" allowed each device to be on its own cable but distributed the same traffic to all the devices on individual cables. Later development produced a device called a "switch" which kept track of what devices were on which cable and only routed traffic to its intended destination. At that point, promiscuous mode was no longer meaningful, with a few exceptions, since none of the other traffic ever reached the device.
It is a device that analyzes and adjusts network traffic and speed to provide optimum performance for all users and applications.

Yes it can and the reason is because of redundancy provides for a backup route or network connection in case of a link failure. The core hardware is typically interconnected to all distribution network hardware and the objective is to ensure that the data traffic continues for the whole network even if a core networking device or link fails.
It depends how much traffic you have on your network, color vs. black and white does not make any difference. It is all based off traffic, video resolution, and what all programs are running on the network

To do that, an additional device is required, a network hub or a network switch, which all computers in the network segment should have to be connected to.
