Differentiate Between a MAC and an IP Address?

A unique number is issued to all networks across devices, which is known as the MAC or Machine Access Control address. This address might be a web-based personal mailbox. It is identified by the network router. The quantity can be changed at any moment. All devices are assigned a unique information processing address, allowing them to be readily located on a laptop and network. Anyone who knows your unique information processing address will contact you via it.
