Switches are Layer 2 devices only while Routers operate at Layer 3.
Switches by definition transfer data frames by readingFrame'sDestination MAC address & sendingitout throughtheport to which mac address (if found in table) is connected. While Routers perform data transfer by reading IP Addresses on Packets.
Switches connect devices within same network number while Routers can connect several networks & support different technologies for data transportation.
A layer 3 switch has routing capability like a router. However, it also has layer 2 switching capabilities like a switch. To fulfill both functions, layer 3 switches will generally have a greater number of ports than most routers.
both are the common inter networking devices(functionally) but the layer 3 switch has the functionality of both switch and router, layer 3 switch are most commonly used in frame relay networks, layer 3 switches are also capable of inter vlan routing
I believe it's a router. I have this question on a test the choices are. router, hub, layer 2 switch or firewall. I answered layer 2 switch. It was wrong.
Routers operate at layer 3 of the OSI model while switches operate at layer 2. The data transmission form of a router is called a packet while in a switch, it is called a frame. Routers are mainly used in wide area networks while switches are used in local area networks.
router operates on Layer 3 and can be used as a switch
The difference between a router and a switch has to do with the layers of the OSI model that they reside in. A switch is a layer 2 device, which means it relies on the MAC (physical) address for switching packets. A router is a layer 3 device, using the network (logical) address. A router also can forward packets to another network; a switch does not do that. In addition, a switch forwards all broadcast packets whereas a router does not forward broadcast packets.
a router or layer-3 switch.
A layer 3 switch or a router.
Depending on the IOS on the switch it will have either layer 3 functionality (EMI) or just layer 2 functionality (SMI).
firewall, router,layer 3 switches and i approve that answer ! NO! In general the firewall is a layer 4 device, it traffics filter incoming and outgoing ports. It uses the function of TCP and UCP. However a Firewall can also be a layer 3 device as in internal firewall in a router. Also a switch is a layer 2 device unless your talking about a Router switch.
Routers operate in layer 3 because they must use the logical network address to determine which network to route the packet to. Logical addressing is a feature of layer 3, therefore a router is a layer 3 device.
A router or a Layer-3 switch can connect 2 or more LANs together and control data flow between them.
