IP Addressing and MAC Addressing

What is IP Addressing

Internet Protocol (IP) addresses are unique numeric identifiers that are needed by every device that connects to the Internet. computers use the unique identifier to send data to specific computers on a network. The IP address acts as a locator for one IP device (anything connected to the internet) to find another and interact with it. An IP address is not always a unique identifier. All computers on the internet use TCP/IP protocol as the standard for how to communicate on the network. In the TCP/IP protocol, the unique identifier for a computer is called its IP address.

MAC Addressing

Mac Addressing is short for Media Access Control address, a hardware address that uniquely identifies each node of a network. MAC addressing is only used in a LAN and it is an identifier assigned to network interfaces for communication. A MAC Address is a piece of information coded into a NIC (Network Information card) in 48 bit binary that allows users to send info between computers in a LAN (local area network).
