what is difference between router bridge and switch?

The key difference between hubs, switches and bridges is that hubs operate at Layer 1 of the OSI model, while bridges and switches work with MAC addresses at Layer 2. Hubs broadcast incoming traffic on all ports, whereas bridges and switches only route traffic towards their addressed destinations.

What Is the Difference? A hub works on the physical layer (Layer 1) of OSI model while Switch works on the data link layer (Layer 2). Switch is more efficient than the hub. A switch can join multiple computers within one LAN, and a hub just connects multiple Ethernet devices together as a single segment.

Switches in general do not perform routing. This is usually done by routers, and the datagrams sent by the router use the link layer address (MAC address in ethernet networks) to send the packet to the next hop.

A router is used to choose the smallest path for a packet to reach its destination. ... The basic difference between a router and a switch is that a router connects different networks together whereas, a switch connect multiple devices together to create a network.

Gateway – A gateway, as the name suggests, is a passage to connect two networks together that may work upon different networking models. ... Gateways are generally more complex than switch or router. 7. Brouter – It is also known as bridging router is a device which combines features of both bridge and router.

The main difference between Layer 2 and Layer 3 is the routing function. ... That means, a Layer 3 switch has both MAC address table and IP routing table, and handles intra-VLAN communication and packets routing between different VLANs as well. A switch that adds only static routing is known as a Layer 2+ or Layer 3 Lite.

Since the BID starts with the Bridge Priority field, essentially, the switch with the lowest Bridge Priority field becomes the Root Bridge. If there is a tie between two switches having the same priority value, then the switch with the lowest MAC address becomes the Root Bridge.

Simply put, a layer 3 switch can forward packets between different networks like a router while layer 2 switches forward packets to different segments/or within a given network. Layer 2 is generally hardware i.e. mac address "routing" or mac tables. Layer 3 has to do with ip's.

KEY DIFFERENCES A Hub is a networking device that allows you to connect multiple PCs to a single network, whereas a Switch connects various devices together on a single computer network. A Hub operates on the physical layer, whereas Switch operates on the data link layer.

A Layer 2 switch only works with MAC addresses and doesn't interact with any higher layer addresses, such as an IP. A Layer 3 switch, on the other hand, can also do static routing and dynamic routing, which includes IP and virtual local area network (VLAN) communications.

Switch is a layer 2 device which works on the basis of MAC address (physical address) of a device. Switch mainly performs these functions: ... (a) Unicast: The switch unicast the frame to the destination only when it has an entry for destination MAC address in its MAC address table.

Router. ... In simpler terms, the Ethernet switch creates networks and the router allows for connections between networks. The majority of routers have a single LAN port and single WAN port, while a switch will have multiple ports for different devices to communicate within the LAN such as PCs and printers.

The main difference between the two devices is that a modem lets you connect to the internet, while a router distributes that connection to different devices. ... For one, modem usually has fewer Ethernet ports than a router. A modem also has a public IP address, which can be accessed over the internet.

What is the fundamental distinction between a Layer 2 switch and a router? Answer: A Layer 2 switch belongs only to its local network, and a router belongs to two or more networks.

Generally speaking, a layer 3 switch connects hosts to form local area networks (LANs) while routers connect multiple LANs into wide area networks (WANs).

A network switch (also called switching hub, bridging hub, and by the IEEE MAC bridge) is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device.

3 Answers. If you mean should you use a router to connect two separate switches to each other at Layer 2 then probably not no. ... Switches are designed to switch within VLANs, and routers route between networks (VLANs). Cisco routers can bridge, but that is an expensive way to switch.
