Why is it necessary to synchronize mutiplexer and demultiplexer in time division multiplexing?
It is necessary to synchronize the mutiplexer and demultiplexer in time division multiplexing because the multiplexor is encoding data onto the carrier at certain points in time. (This is why its called Time Division Multiplexing) The demultiplexor most know when the data of interest are present in the carrier, hence the need for synchronization. Note that there usually is a transmission delay between the multiplexor and demultiplexor. As a result, while the demultiplexor is in sync with the multiplexor, it is not necessarily in phase. The crucial point is that the data and clock be in sync and in phase at the demultiplexor.
Can I use a Netgear router to get the best performance out of my home network?
Yes. Netgear is a very popular and easy router to use at home, they have a good website for information if you need also any help also.
Can you put an internet filter on your router?
Unless your router has a mirroring port.
So you can connect an internet filtering product (eg: WFilter) to the mirroring port in your router to do monitoring and filtering.
Where can one make their network private?
One can set up their private network using many different methods. One method is to place a WEP on one's network, to at least prevent casual users from entering.
Are CNC router's any good for home use?
CNC router's are good for home use and even good to use for a small business. Depending on what type and how much material you would be cutting it might be a very good choice to put one in your house.
Yes, you can. It's "Bridge".
PS: Not many routers support "Bridge". And it's a little bit tricky to set up.
Where is lead most commonly found in older buildings throughout the region?
Usually in between the walls. Lead restricts some signal and radio waves from passing through.
Example: On one side of the wall I have a router, and in the other room on the other side I have my laptop. For some reason the signal isn't getting through very strongly, so I suspect that there is lead in between the wall. I positioned it near a plastered wall and it worked fine.
How do you set up wifi on a pandigital novel?
Depends on type of WIFI I think. Mine's always on, broadband, with the box by Motorola. Enable the wifi and the Pandigital should find the signal. You then should just have to input the password that should have been supplied with the box. On the Motorolas, that number is about a dozen digits and it will be somewhere on the box.
You may have to set it up manually. Then you'll need the SSID. Mine, Motorola based, is 2WIRE541. You then need to input type of security - if you don't know, try the 3rd, WPA2, then again you need the password. Good luck
Will ad-hoc networks contain access points?
An ad-hoc network does not require an access point. Typically, if an access point is involved then it is not strictly an ad-hoc network, but would be an infrastructure network.
Sensor network comprises of scattered sensor nodes with limited computational capabilities and battery power. The existing security solutions for traditional wireless networks can not be used because of the constraints associated with sensor network. We present secure sink node architecture as two-tiered scheme for sensor network security. The architecture protects the sink node from unauthorized access by surrounding it with two protection layers. Sink nodes listen to only inner layer nodes and inner nodes are allowed to communicate with only outer layer nodes. These protection layers are formed in an intelligent manner without violating constraints specific to sensor network. In order to enhance security, protection layers are re-adjusted in case of an attack. We present statistical analysis to elucidate the performance of proposed architecture.
Try moving your WiFi router. The signal could be too weak or there could be thick walls, thick floors, or other things in the way.
What does the T mean in 10Base-T?
It stands for 'twisted pair'. 10BaseT or Ethernet cable consists of two pairs of wires twisted around each other inside an external sheath.
How do you determine if a website uses IPv4 or IPv6?
You can use this to try and parse it: IPAddress.TryParse
Then check AddressFamily which
Returns System.Net.Sockets.AddressFamily.InterNetwork for IPv4 or System.Net.Sockets.AddressFamily.InterNetworkV6 for IPv6.
EDIT: some sample code. change as desired: string input = "your IP address goes here";
IPAddress address;
if (IPAddress.TryParse(input, out address))
{
switch (address.AddressFamily)
{
case System.Net.Sockets.AddressFamily.InterNetwork:
// we have IPv4
break;
case System.Net.Sockets.AddressFamily.InterNetworkV6:
// we have IPv6
break;
default:
// umm... yeah... I'm going to need to take your red packet and...
break;
}
}
Why can't I get any Internet on my laptop even though I am connected to my router?
Depending on your home network setup, there could be many different reasons why you can't access the internet. For a setup that you are describing, you would need a setup like the following to have your hardware correct to reach the internet.
Hardware:
cable/phone/satellite feed-->modem--->router--->device connected to router.
Assuming that you have that setup, you would then need to make sure that all the software (programs) for the various devices I just described are installed correctly and in working order. If you've done that, the final step would be to make sure that you have all the settings correct across those various devices so that you can connect to the net. Unless I know your specific setup, I really can't be more precise.
The setup above is correct, and I think all the settings are right, and my router works fine because I am able to connect other devices to it. I sometimes have a connection through my laptop but then it will sometimes it will go off and I am not sure why.
What is used to determine if the host is local or remote?
It could be said that the most "local" host is the machine you are typing on, but that realization is not always implicit in the design of the protocol you are using. Also, computers on the same physical network can be considered local, as can be considered computers within the same address space - it really depends on your definition of "local" and "remote".
If you're thinking about "geographical locality", IP address groups are assigned to countries, and then sometimes subdivided into states or cities, where applicable and possible, and there exist services on the World Wide Web that access this publicly available information in order to provide at least a rough approximation of the host's geographical localization.
However, the most common idea thought about when speaking of "local" and "remote" hosts, is the idea of logical network placing - ie. a computer will be considered "local" if it belongs to the same address space (in this case, the IP/mask calculation will be performed, and will include any specific routing information, to arrive at a conclusion).
Also, any computer you are connecting to can be considered the "remote host" - even your own! That is simply because the "other end" of a connection can be called "remote" just because it's on the other side of said connection (in this case, just the connection itself will differentiate the two sides of it). As I've pointed out above, it really depends on your definition of "local" and "remote".
It is also worth keeping in mind that from the perspective of the computer you're trying to contact, you are the remote host!
Describe a TCP connection sequence?
The connection establishment process actually accomplishes
several things as it creates a connection suitable for data
exchange:
o Contact and Communication: The client and server make
contact with each other and establish communication by
sending each other messages. The server usually doesn't even
know what client it will be talking to before this point, so
it discovers this during connection establishment.
o Sequence Number Synchronization: Each device lets the
other know what initial sequence number it wants to use for
its first transmission.
o Parameter Exchange: Certain parameters that control the
operation of the TCP connection are exchanged by the two
devices.
I need WiFi driver for Toshiba L40 laptop?
To download original, up-to-date drivers for the various hardware components of your computer, please visit your manufacturers website.
All name brand manufacturers websites have vast Support sections where detailed instructions are kept on how to update or reinstall drivers for any piece of hardware that initially came with your computer.
I Changed My front hub but my front end still wobbles?
you need an alignment, badly....or your bearing snapped. call a mechanic, and tell them your vehicles' symptoms. they'll tell ya the same thing i just did
What is the explanation for the types of Switching systems?
There are three type of switching system such as circuit switching ,packet switching , massage switching.
Which protocol used for routing?
A routing protocol is a protocol that routers use to tell each other about available routes. Some of the routing protocols include RIP, EIGRP, OSPF, IS-IS, BGP.
