Switches and hubs are both networking devices that allow multiple devices to connect to a network, but they differ in how they transmit data to the devices.
A hub is a simple networking device that broadcasts data to all the devices connected to it. When a device sends data to the hub, the hub forwards the data to all the other devices on the network. This means that all devices receive all the data transmitted on the network, even if the data is intended for only one device. Hubs are less expensive than switches but are less efficient in transmitting data since they cannot differentiate between devices.
On the other hand, a switch is a more intelligent networking device that transmits data only to the device for which it is intended. When a device sends data to the switch, the switch determines which device is the intended recipient and transmits the data only to that device. This makes data transmission more efficient since it reduces the amount of unnecessary data transmitted on the network. Switches are more expensive than hubs but are more efficient and offer better network performance.
In summary, the main difference between a switch and a hub is how they transmit data to the devices on the network. A hub broadcasts data to all devices, while a switch transmits data only to the intended recipient device. Switches are more efficient but more expensive than hubs, which are less efficient but less expensive.
