How do you see the configurations of all the network cards using the ifconfig?
Start->Run->cmd->ipconfig.
You will see information about your network adapters.
What class of network is reserved for special purposes?
A class D network is reserved for multi-casting.
The class E series of network addresses are reserved for experimental purposes. 240 - 255 are reserved for class E addresses.
How many bits would you borrow to subnet 172.16.100.0 to have at least 500 hosts?
we need to borrow 7 bits to subnet 172.16.100.0 to have at least 500 hosts and the subnet mask will be 255.255.254.0
What is a valid reason for a switch to deny port access to new devices when port security is?
The denied MAC address are statically configured on the port
What is Crossbar Switches and Multistage switch in Space Division Switch?
2.TIME DIVISION
SPACE DIVISION has two parts i:e crossbar and multistage switches.crossbar switch-A crossbar switch connects n inputs to m outputs in a grid,using electronic micro switches(transistors) at each crosspoint.To connect n inputs to m outputs using a crossbar switch requires n*m crosspoints.The major limitation of this design is the no of crosspoints required.for example:To connect 1000 inputs to 1000 outputs requires a switch with 1.000,000 crosspoints.A crossbar switch with this no of crossspoints is impractical.such a switch is also inefficient because statistics show that,in practice,fewer than 25% of the crosspoints are in use at any given time. The rest are idle.multistage switch-The solution to limitation of the crossbar switch is the multistage switch,which combines crossbar switches in several(normally three)stages.In a single crossbar switch,only one row and one coloumn is active for any connection.so we need n*n crosspoints.If we can allow multiple paths inside the switch ,we can decrease the no of crosspoints.Each crosspoints in the middle stage can be accessed by multiple crosspoints in the first or third stage.The multistage switch has one drawback-blocking during periods of heavy traffic.The whole idea of multistage switching is to share the crosspoints in the middle stage crossbars.What is the purpose of twisting wires closely together as in twisted-pair cable?
To minimize crosstalk
The only way that could work is if the DHCP service and the HTTP service were configured and running on the same physical machine. Otherwise they could not use the same IP address.
DHCP and HTTP do not have to be on separate machines (but it is a good idea to separate them in a network).
A better question might be why the two services *require* the same IP address.
The state of directly connected links
Depends on what your doing, most common use today is for POE (power over ethernet)
- cables are ethernet cables that you can use to create a network between two computers?
Crossover cables are used to connect like-hardware devices or to connect anything other than a hub or switch to a computer. The crossover cable connects the four pins that are used to communicate traffic over the cable together between the two devices.
Most network adapters manufactured recently can automatically sense a straight-through cable and auto-switch accordingly. All gigabit NICs are capable of this.
How do you disassemble gateway e 4000?
First of all: If you don't know what you are doing, be very careful about taking things apart. Note which parts have come from where, especially power cable. When taking a computer apart, make sure you know what your aim is, and only take out the parts necessary. For example if you are replacing a fan, only remove the fan and any parts that are in the way of removing the fan. To take apart any computer the first thing to do is remove the covers, usually held on at the back with 4 screws. Once removed you will be able to slide of the side panels and see all the components. At this stage I would recommend anyone who is confused by what they are looking at to stop and do some research on the components that make up a computer. Remove the parts that you need to, noting directions of clips, where cables are connected etc. Remember always remove static from your body by touching something that is earthed. You might be lucky the first few times, but when you screw up a $200 component, you will wish you had bothered earthing. Take care and play safe
What is the full expression of the abbreviation HUB switch?
Hub is not an abbreviation. A hub is the center of a wheel; that's where the name of the networking hub is derived from.

A home folder is a place where you can store all of the things that you use the most on a computer. You can use the home folder to access the internet, store your photos, or keep music files.
Does this printer have wireless capability?
You don't give a model number. Most recent (last year or so) computers would have wireless abilities.
You should be able to go to the manufacturer's website and look up the model number.
Why multilayer reference model preferred over single layers structure?
multi layered reference model is preferred over single layered model because each layer has to take care of a limited number of objectives.hence the design an implementation can be streamlined and made very robust because the number of abnormal conditions to be handled is limited.
every layer is assumed to be autonomous.this means that a portion of a stack from one user to manufacturer can easily inter-operate with a portion of the stack from another manufacturer.the user thus gets the advantage of competition among stack vendors at every layer.
What is the relationship between a neutral network and a local area network?
The only relationship I can come up with is that they are both networks - a series of nodes connected with links.
A neural network, like the one in your brain, has brain cells as the nodes, and synapses as the links. An artificial neural network, which is a tiny crude simulation of how your brain works that runs on a computer, emulates that structure in software.
A local area network has computers and routers as the nodes, and various kinds of data transmission lines (such as Ethernet cables) as links.
Yet another kind of network is a fishing net - it has knots as nodes, and strings as links.
Perhaps a better answer would be:
The relationship between a neural network and local area network is the same thing as the relationship between a local area network and a fishing net.

What will happen if you enable both wireless and lan connection?
They will both work. I would imagine the interrupt levels will determine which one will intercept the traffic from a request first. i.e browser, explorer, ping Any request made through one adapter will receive back to the same adapter. That is to say - if you make a browser request to the internet and it goes out on the wired adapter, it will come back to that same adapter. The end-to-end addressing is in the message traffic, and whatever adapter address (MAC address) is passed outbound will be in the addressing in the incoming message, and consequently go to that (MAC) address. I would think if the wired adapter is busy and you made a request, the request would be honored by the wireless adapter, and the answer would come back to that adapter. I believe it would also look to be simultaneous, even though that is a tricky concept, considering it's all serial to and through the modem/gateway.
What happens if duplicate addresses exists on a lan?
Any attempt to use an already existing address on a LAN will be rejected, and the second or succeeding system will have their address set to 0.0.0.0.
Duplicate addresses are not allowed in a LAN; the addresses must be unique.
