explain modem and switch in details atleast 20 lines. No spamming or google answers.

Switch
An Ethernet/LAN switch creates a virtual network between two networked devices for the duration of the data transfer. This is unlike a hub which forwards all received data to all connected devices, even though the data may be destined for just one of those devices. A switch learns the association between the MAC addresses of connected devices and its switched ports. By sending data only to where it needs to go, a switch reduces the amount of data on the network, thereby increasing the overall performance of the connected devices. A switch also improves security, since data is not broadcast to every connected device, but only to the device for which it is destined, it cannot be monitored by other connected devices
Modem
A modem is a hardware device that converts data into a format suitable for a transmission medium so that it can be transmitted from computer to computer. A modem modulates one or more carrier wave signals to encode digital information for transmission and demodulates signals to decode the transmitted information
Hope it's help uh
