You just turned on a four port Ethernet switch (it hasn’t learned any addresses yet) and connected a host to each port. You send
packet #1 from 00:11:22:33:44:55 to 66:77:88:99:00:11 which arrives at port 1 of your switch. Next, packet #2 is sent from 22:33:44:55:66 to 00:11:22:33:44:55 which arrives at port 3 of your switch. Which of the following are true? 1. Packet #1 is broadcast on all ports
2. After the first packet is received, the switch associates 66:77:88:99:00:11 with port 1
3. Packet #2 is only sent out on port 1
4. Packet #2 is sent out on ports 1, 2, 4
When the user recently switched over that port Ethernet device, which is, no addresses have yet been acquired as well as a client has been linked on each port. He sends #1 packet from 00:11:22:33:44:55 to 66:77:88:99:00:11 arriving at the device's port 1. Next packet #2 is transmitted between 22:33:44:55:66 to 00:11:22:33:44:55 that appears at the switch's port 3.
So that the Package # 2 will be sent only through port 1 by the user who switched over the network.
Search engines are evaluated on the basis of the variables which are used by the search engines to determine where the URL appears in the list of the search results.There are certain algorithms are also implemented using these variables like panda algorithm.So we conclude that the answer is True.
