Switches are data link layer devices that, like bridges, enable multiple physical LAN segments to be interconnected into a single larger network. Similar to bridges, switches forward and flood traffic based on MAC addresses. Any network device will create some latency. Switches can use different forwarding techniques-two of these are store-and-forward switching and cut-through switching. In store-and-forward switching, an entire frame must be received before it is forwarded. This means that the latency through the switch is relative to the frame size-the larger the frame size, the longer the delay through the switch. Cut-through switching allows the switch to begin forwarding the frame when enough of the frame is received to make a forwarding decision. This reduces the latency through the switch. Store-and-forward switching gives the switch the opportunity to evaluate the frame for errors before forwarding it. This capability to not forward frames containing errors is one of the advantages of switches over hubs. Cut-through switching does not offer this advantage, so the switch might forward frames containing errors. Many types of switches exist, including ATM switches, LAN switches, and various types of WAN switches. Asynchronous Transfer Mode (ATM) switches provide high-speed switching and scalable bandwidths in the workgroup, the enterprise network backbone, and the wide area. ATM switches support voice, video, and data applications, and are designed to switch fixed-size information units called cells, which are used in ATM communications. Figure 4-3 illustrates an enterprise network comprised of multiple LANs interconnected across an ATM backbone. Figure 4-3 Multi-LAN Networks Can Use an ATM-Based Backbone When Switching Cells
LAN switches are used to interconnect multiple LAN segments. LAN switching provides dedicated, collision-free communication between network devices, with support for multiple simultaneous conversations. LAN switches are designed to switch data frames at high speeds. Figure 4-4 illustrates a simple network in which a LAN switch interconnects a 10-Mbps and a 100-Mbps Ethernet LAN.

The difference among different types of switching devices is in the features and the functions that they have. The two main types are packet switching and circuit switching devices.
Facebook, LinkedIn, MySpace, and pintrest are some good networking devices. Less traditional networking devices include parties, job fairs, professional meetings, etc. The goal of networking can help determine what the best networking idea is.
No, there is not any difference between the switching action of a relay and a contactor. Both of these devices are operated by an electro magnetic coil.
added device called networking
Yes, they are devices that operate at different layers of the OSI model for networking.
Internetworking devices which means its efficient and performance is up to the mark. But in networking devices there is a lot of problems when we are sending the packets from one computer to another computer.So its difficult to work with networking devices compare to interconnecting devices. Cost is moderately high in this..
Transistors are used for switching devices! What gave you the idea they aren't?
Defects in networking devices are malware-infected computer,broadcast storms....
How networking media devices and software work together to provide data networking services?
The difference can be quite different or quite similar depending on the context by which both are used. If your speaking IT then theres some bit of similarity but a bit of difference also as they both fall under each other. Networks are multiple computers or devices that interconnectable and capable of speaking with each other in a general area. The term networking describes more the act or occupation of assembling, configuring and troubleshooting a network of devices or computer so as they are able to speak with eacother.
