what is the ip address

How does IP address and MAC address work in parallel?
the internet works in the same way as postal services. instead of sending mail, the device sends 'data packets', and the ip address or mac address determines where the packets will come.
How IP addresses work
any device connected to a network such as a computer, tablet, camera, etc., will need a unique identifier for other devices to know how to access it. in the tcp / ip protocol, that identifier is called an internet protocol address or ip (internet protocol - ip) address.
