What are the functions that enable a switch to forward Ethernet frames in a lan?
A switch forwards Ethernet frames in a LAN primarily through two functions: MAC address learning and frame forwarding. It maintains a MAC address table by learning the source MAC addresses of incoming frames and associating them with the corresponding switch ports. When a frame is received, the switch looks up the destination MAC address in its table to determine the appropriate port to forward the frame, ensuring efficient data transmission within the network. If the destination MAC is unknown, the switch will broadcast the frame to all ports except the one it originated from.
Internet is a public lan?
All IPv4 IP addresses can be divided into two major groups: global, or public, or external - this group can also be called 'WAN addresses' — those that are used in the Internet, and private, or local, or internal addresses — those that are used in the local network (LAN).
What are two addresses required for communication in Internet?
logical and mac
What are two features of ARP?
Address Resolution Protocol (ARP) primarily features two key functionalities: it maps IP addresses to MAC addresses, enabling devices on a local network to communicate effectively. Additionally, ARP operates within a local area network (LAN) and utilizes broadcast messages to discover the MAC address corresponding to a specific IP address, facilitating the transmission of data packets between devices.
Why are no two MAC addresses the same?
the network could not work if they were the same.
What effect will it have on the network if two devices from two different manufacturers share the last 24 bits of their MAC addresses?
It should not cause any problems on the network since the first 24 bits of the MAC addresses are different.

It should not cause any problems on the network since the first 24 bits of the MAC addresses are different.
How come MAC addresses don't run out -- how do manufacturers know which ones they can reuse?
MAC addresses don't really run out, they get reused, and they distribute to different parts of the world so there is a smaller chance of two addresses being on the same network.
What is commonly used to restrict access to a network based on the physical hardware address of the clients network device?
You can enable MAC address (also know as Physical Address) filtering. MAC address filtering has two modes: 1. Allow access to listed MAC addresses 2. Deny access to listed MAC addresses.
How many ip addresses can be assign in one lan card for xp os?
we have assign two ip address in one lan card. first we put the lan card in DHCH mode Then highlight the alternative ip address block, give their manual ip address.
Is it true that the IPv6 addresses in Windows 7 computers use six byte hexadecimal sequences hard coded into each network interface adapter by the manufacturer?
I think you are mixing up two different protocols. IPv6 addresses are not hard coded into your adapter; MAC addresses are. It's totally different. IPv6 addresses are 16 bytes long and MAC addresses are 6 bytes long.
What is Mac address of the wireless adapter?
MAC addresses are a kind of serial number. They are supposed to be unique worldwide; that is, two different network equipments, even of the same kind, will have different MAC addresses. They are used for communication, to identify the individual pieces of equipment.MAC addresses are a kind of serial number.
