What is the difference between MAC and IP?

The primary use of a MAC address is to ensure the physical address of a given device/ computer. The IP address, on the other hand, defines a computer’s logical address. The MAC address primarily operates on the data link layer. The IP address primarily operates on the network layer.

What is a unique identifier assigned to a physical network interface card?

MAC Address (Media Access Control address): Also known as physical address, is the unique identifier of each host and is associated with the NIC (Network Interface Card).

What is a MAC address used for?

A media access control address (MAC address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth.

Is hardware address the same as MAC address?

The MAC (Media Access Control) address is a devices hardware address. Each device on a local area network must have a unique MAC address assigned. The MAC address is often referred to as the Ethernet Address on an Ethernet network. They are in fact the same thing.

What is ARP and RARP in computer networks?

ARP stands for Address Resolution Protocol. Whereas RARP stands for Reverse Address Resolution Protocol. 2. Through ARP, (32-bit) IP address mapped into (48-bit) MAC address. Whereas through RARP, (48-bit) MAC address of 48 bits mapped into (32-bit) IP address.

What is ARP protocol?

Address Resolution Protocol (ARP) is a protocol or procedure that connects an ever-changing Internet Protocol (IP) address to a fixed physical machine address, also known as a media access control (MAC) address, in a local-area network (LAN).

What is the meaning of NIC?

Network interface controller
NIC is an acronym for Network interface controller, but it can also be known as a network adapter or LAN network. It is a piece of computer hardware, used for connecting a computer to a network, either through cables or wirelessly.

What is an example of MAC address?

The MAC address is a 12 digit hexadecimal number that is most often displayed with a colon or hypen separating every two digits (an octet), making it easier to read. Example: A MAC address of 2c549188c9e3 is typically displayed as 2C:54:91:88:C9:E3 or 2c-54-91-88-c9-e3.

What is IP and MAC binding?

Mac-binding essentially means binding together the MAC and IP addresses, so that all requests from that IP address are served only by the computer having that particular MAC address. In effect, it means that if the IP address or the MAC address changes, the device can no longer access the Internet.

Why we need both MAC and IP address?

MAC Addresses handle the physical connection from computer to computer while IP Addresses handle the logical routeable connection from both computer to computer AND network to network.

Why IP address is called logical address?

An IP address is a logical address that is assigned by software residing in the router or server, and that logical address can change from time to time. For example, a laptop is likely to be assigned a new IP when it starts up in a different hotspot (see DHCP).

Can two devices have same MAC address?

If two devices have the same MAC Address (which occurs more often than network administrators would like), neither computer can communicate properly. On an Ethernet LAN, this will cause a high number of collisions. Duplicate MAC Addresses on the same LAN are a problem.
