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.
HUB in a collision Domain, Switch in Local Network.Broadcasting in network is done to locate devices in Network. Hub broadcasts through all its port whereas Network Switch Broadcast traffics within a Port & out of all ports only if new device is to be found.
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.
A hub does not aid in network segmentation. Unlike switches and routers, which can create separate broadcast domains and manage traffic between different network segments, a hub simply broadcasts data to all connected devices in a single segment. This lack of traffic control makes hubs unsuitable for improving network performance or security through segmentation.
Peer-to-peer
A network router handles and manages all network traffic by directing data packets between devices on a local network and external networks, such as the internet. It uses routing tables and protocols to determine the best paths for data transmission, ensuring efficient communication. Additionally, routers can implement security measures like firewalls and traffic monitoring to protect the network and optimize performance.
all VLANs
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.
master firewall that all traffic flows through
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
A network bridge is a device which connects two parts of a network together at the data link layer (layer 2 of the OSI model).Network bridges work similarly to network switches, but the traffic is managed differently. A bridge will only send traffic from one side to the other if it is going to a destination on the other side. This is different to a layer 1 switch which sends all traffic from either side. Sometimes network bridges are called layer 2 switches.Since they need to look at the contents of the traffic going into them, they are much more complicated than a hub or repeater
