What information must be included within a unicast message for it to be delivered on an Ethernet network?
MAC and IP addresses that correspond to a destination host. Remember, Unicast is singular.
Does hub has Mac address?
No. Hubs simply repeat all the Ethernet frames on all ports and do not interfere with the source or destination MAC addresses and as such do not need their own MAC address.
What is the full form of ieee standard 802.3?
MAC addresses are formed according to the rules of one of three numbering name spaces managed by the Institute of Electrical and Electronics Engineers (IEEE)
Which protocol's header includes the source MAC address?
The Ethernet protocol's header includes the source MAC address.
What is a private MAC address?
A MAC address is unique to your ethernet card. MAC addresses are used within an Ethernet network to uniquely identify the source and destination of Ethernet frames. ARP (Address Resolution Protocol) is used on IP networks to map IP addresses to MAC addresses within an Ethernet network.

What type of address is used in an Ethernet frame header?
MAC addresses only
How many potential MAC address schemes are possible?
The original IEEE 802 MAC address comes from the original Xerox Ethernet addressing scheme. This 48-bit address space contains potentially 248 or 281,474,976,710,656 possible MAC addresses.
Which protocol is used to convert logical IP addresses to physical MAC addresses?
Address Resolution Protocol (ARP)ARP is primarily used to translate IP Addresses to Ethernet MAC Addresses.
Can there be more than one Ethernet adaptors that have the same Ethernet MAC address?
One computer must have unique MAC addresses for each Ethernet adapter (ideally each Ethernet adapter in existence has a unique MAC address but there are some that allow manual setting of the MAC, so duplicates can exist.) If you have not changed anything from the factory settings then each network card will have a unique address!
What if there are no mac addresses and all adapters use ip addresses?
Ethernet devices are identified by their MAC address, not an IP address. If their were no MAC address incorporated into the device then it is not following the rules define for the ethernet protocol. It would not be an ethernet network adapter or it would be a defective ethernet network adapter. As the LANs are designed for arbitrary network layer protocols, not just IP, so if the adapters are assigned with IP addresses rather than MAC addresses, than it will be difficult for adapters to support other network layers. Even if the adapters use entire network layer addressing schemes, they will need to be reconfigured every time they are powered up. So it is imperative to use neutral MAC address independent of network layer addressing schemes in order to ensure better performance of network.
What is the primary purpose of ARP?
The primary purpose of the Address Resolution Protocol (ARP) is to map an IP address to a MAC address in a local network. This allows devices on a network to communicate with each other using their unique MAC addresses. ARP is crucial for proper functioning of Ethernet-based networks.
How are data link layer Ethernet addresses normally written down?
Data link layer Ethernet addresses, also known as MAC (Media Access Control) addresses, are typically written in hexadecimal format, consisting of six pairs of two-digit numbers separated by colons or hyphens. For example, an Ethernet address might be represented as "00:1A:2B:3C:4D:5E" or "00-1A-2B-3C-4D-5E". Each pair corresponds to a byte (8 bits) of the address, with the entire MAC address being 48 bits long.
What is Ethernet addressing?
Ethernet addressing refers to the method used to identify devices on an Ethernet network through unique hardware addresses known as MAC (Media Access Control) addresses. Each device on the network is assigned a 48-bit MAC address, typically represented in hexadecimal format. This address ensures that data packets are delivered to the correct device within a local area network (LAN). Ethernet addressing is essential for facilitating communication between devices in a networked environment.
Where is a MAC address stored in a Switch?
Switches store the MAC addresses in an internal database called MAC Address Table. The entries in that table can be addresses learned by the switch or that can be entered manually by the switch administrator. This table is analogy to a router's routing table, only a switch operates at layer 2 whereas the router operate at Layer 3.
What information must be included within a unicast message for it to be delivered on an Ethernet network?
MAC and IP addresses that correspond to a destination host. Remember, Unicast is singular.
