Wikipedia says:
In computing, promiscuous mode is a configuration of a network card
that makes the card pass all traffic it receives to the central
processing unit rather than just packets addressed to it — a feature
normally used for packet sniffing.
Each packet includes the hardware (Media Access Control) address. When
a network card receives a packet, it checks if the address is its own.
If not, the card normally drops the packet. But in promiscuous mode,
the card doesn't drop the packet, thus allowing the computer to read
all packets.
Last 2 senteces are easiest description of promiscuous mode on network card.

Hello everybody,
I have a question concerning "Promiscuous Mode", I know what it is,
but I would like to know exactly what is happening behind the scenes
when I change my NIC to this mode
For example: what is the technicality in writing the command:
ifconfig eth0 promisc?
Your help is so much appreciated.
Best regards.
