What is L3 switch?
An L3 switch is sort of like a high powered router. These switches use hardware to route packets of information, as opposed to a regular router which uses software.
Defference between router and L3 switch?
A router can provide firewall protection, port forwarding, DSL login information and data encryption and a host of other features that a simple data switch cannot.
What is main difference between a Layer 3 switch and a router?
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.

What is the difference between the router and the hub?
A hub (or L2 switch) performs data bridging/switching/forwarding at the OSI Layer 2 level for data destined to another address on the same subnet. For data to be forwarded to another subnet, that data must be routed at the OSI Layer 3 level which is performed by a Router (or L3 Switch). Routers collect various information about other networks it can forward traffic to and from, what routing protocols are used and which path(s) to forward that data to.
Is gomphosis a joint between L2 and L3?
Gomphosis is a type of joint that connects teeth to the jawbone, not between vertebrae like L2 and L3. The joint between L2 and L3 is called an intervertebral joint or a symphysis joint, where the fibrocartilaginous disc sits between the two vertebrae.
What's the difference between a switch and a router?
brief: A router essentially determines which way is the shortest or fastest in a network, and routes packets accordingly. It works at layer 3 of the OSI model, moving packets from one port to another based on L3 addresses - ie. IP addresses, IPX addresses, etc. A bridge connects one point to another in a network permanently. It works at layer 1 and 2 of the OSI model.
What technology is use in L2 and L3 switches?
Basically a layer 2 switch operates utilizing Mac addresses in it's caching table to quickly pass information from port to port. A layer 3 switch utilizes IP addresses to do the same. While the previous explanation is the "What", for folks in networking the following "How" is far more interesting. Essentially, A layer 2 switch is essentially a multiport transparent bridge. A layer 2 switch will learn about MAC addresses connected to each port and passes frames marked for those ports. It also knows that if a frame is sent out a port but is looking for the MAC address of the port it is connected to and drop that frame. Whereas a single CPU Bridge runs in serial, todays hardware based switches run in parallel, translating to extremly fast switching. Layer 3 switching is a hybrid, as one can imagine, of a router and a switch. There are different types of layer 3 switching, route caching andtopology-based. In route caching the switch required both a Route Processor (RP) and a Switch Engine (SE). The RP must listen to the first packet to determine the destination. At that point the Switch Engine makes a shortcut entry in the caching table for the rest of the packets to follow. Due to advancement in processing power and drastic reductions in the cost of memory, today's higher end layer 3 switches implement a topology-based switching which builds a lookup table and and poputlates it with the entire network's topology. The database is held in hardware and is referenced there to maintain high throughput. It utilizes the longest address match as the layer 3 destination. Now when and why would one use a l2 vs l3 vs a router? Simply put, a router will generally sit at the gateway between a private and a public network. A router can perform NAT whereas an l3 switch cannot (imagine a switch that had the topology entries for the ENTIRE Internet!!). In a small very flat network (meaning only one private network range for the whole site) a L2 switch to connect all the servers and clients to the internet is probably going to suffice. Larger networks, or those with the need to contain broadcast traffic or those utilizing VOIP, a multi network approach utilizing VLANs is appropriate, and when one is utilizing VLANs, L3 switches are a natural fit. While a router on a stick scenario can work, it can quickly overtax a router if there is any significant intervlan traffic since the router must make complicated routing decisions for every packet that it recieves.
How do you know which leads are L1 L2 L3 on a 3 phase 2 speed motor?
You can identify the leads by using a multimeter to measure the resistance between each lead. The resistance between L1 and L2 should be higher than between L1 and L3 and L2 and L3. You can also consult the motor's wiring diagram for guidance.

What is the role of supervisor engine in routers or switches?
A router doesnt have a Supervisor Engine. whereas a switch requires a supervisor Engine. A Switch like 6500 and 4500 can't work without a Supervisor Engine. A Sup Engine works like a brain of the L3 chassis type switches. All the data forwarding decisions are take by the Sup Engine. suppose you have a service module based switch like 6500 and 4500 switch then by just upgrading the service module can help you enhance the switching capacity to 10G from 1G. If using Sup Engine 720.
