What are the advantages of switch?
Switch is faster than HUB. If you are using managed switch you can create VLAN, you can secure ports and many other things.
A subnet created by moving the subnet boundary to the leftis called?
Moving a subnet to left to save bits is known as a supernet.
How is TCP connection-oriented but IP connectionless?
TCP is known as a connection-oriented protocol, which means that a connection is established and maintained until such time as the message or messages to be exchanged by the application programs at each end have been exchanged.that connection is virtual only...
Topology network formula and for example?
Only the formula required is for mesh topology. i.e.
The number of connections in a full mesh = n(n - 1) / 2.
What is the impact on Organisations for the loss of service?
The impact on organizations for the loss of service include possible complaints to the press and customer dissatisfaction. It will also result in a loss of earnings for the company and does not do anything positive for their reputation.
What is the logical topology for mesh topology?
topology is function of x..........then the family of x belong to topology
Why is a switch called as layer 2 device?
because one layer is the electrical part, and the other layer is the place where the switch is on.
there are three types of switching techniques
1) circuit switcching
2) Packet switching
3)Message switching
because the tcp is reliable
What does a invalid IP address mean?
invalid ip address means which password you who are not correct.
What is a fully peered network?
All peers must be at the very same level. There must not be a server or any peer neither indexing nor monitoring the network.
When considering security what is the major drawback of implementing physical tokens?
Mass distribution of such devices is costly.
The DHCP protocol is used for this purpose.
How many port numbers are there?
There isn't really a limit to the amount of ports, ive seen a port 9999 before,
I often use high number ports that arnt assigned to anything.

The layer enables two applications on the network to have an ongoing conversation or dialog?
Session layer
Is star topology the faster of all topology?
No, because there is a hub between star topology and every station connect to that central hub. hub cause broadcast and congession since packet loss is more likely to occur. I suggest that mesh topology is more faster as there is a dedicated link to each node.
If the logical destination address of the packet is corrupted what will happen to the packet?
The receiver acknowledges packets it has received, and if the sender doesn't get an acknowledgment, it will eventually re-send the doubtful packet
Describe how a switch learns addresses?
A switch examines the frame for the MAC address information and adds it to its internal switching table as each frame passes through the switch.
