What is network switching?

Answer 1

It's when you switch networks..

if your talking about network switching subsystem;

Network switching subsystem(NSS) (or GSM core network) is the component of a GSM system that carries out call switching and mobility management functions for mobile phones roaming on the network of base stations. It is owned and deployed by mobile phone operators and allows mobile devices to communicate with each other and telephones in the wider Public Switched Telephone Network or (PSTN). The architecture contains specific features and functions which are needed because the phones are not fixed in one location.

Answer 2

A switch is multiple ethernet port, where connected more than one Pcs and get shareing data, application each other. it is called network switch.

Answer 4

A switch is a device which is used to connect computers together and/or to share the internet . A switch is generally more intelligent. Unlike hubs, network switches are capable of inspecting data packets as they are received, determining the source and destination device of each packet, and forwarding them appropriately. By delivering messages only to the connected device intended, a network switch conserves network bandwidth and offers generally better performance.

Answer 5

Network switching in the realm of computer networks is nothing more than connecting multiple computers, printers, and other devices into the network so that they can communicate. This is the modern version of a concentrator (commonly improperly called a hub).

To explain, when Ethernet was first born, all stations were connected to the network through a concentrator and all machines heard all the broadcasts on the network. While the number of computers (or other devices) involved were minimal and the amount of communication across the wire, this was manageable. However, as more devices were added to the network, things got hectic and spun way out of control. The reason being that the way that stations broadcast was by listening to the network cable to see if anyone else was broadcasting. If not, then the station would start its transmission. The problem is that the delay in whether to broadcast was determined by a randomly-set timer. If there were two stations that listened at the same time, heard nothing, and then started broadcasting at the same time, the concentrator would hear this collision and broadcast a jam signal which would cause all stations to reset their internal delay timers to random intervals and the process would start all over again. On small networks, the number of collisions was minimal but if there were more stations, the number of collisions escalated and communication speed took a nosedive.

To get around this, the network switch was created. Rather than everyone communicating with everyone else at the same time, the switch receives the data that is being broadcast from one station and reads the header information to determine to which port to send it to get to its destination. None of the stations on any of the other ports hear that communication. This allows multiple broadcasts to occur at the same time since there are "virtual private circuits" set up between sender and recipient. As such, networks run at near-full speed at all times. Another advantage is that a network can have a mix of slower and faster devices (such as printers that communicate only at Fast Ethernet speed (100Mbps) and computers that communicate at Gigabit Ethernet speed (1000Mbps, aka 1Gbps)) and no one on the network is affected since the switch slows down the data being sent to the slower device or speeds it up for a faster device as needed.

In the modern day, one uses switches in networks and only rarely does a network engineer run into something as antiquated as a concentrator.
