Help me clarify: Difference between Joining and Extending Wireless Network

I've eventually figured out how to get my AirPort Express to allow my Mac Pro access to the internet Via Ethernet cable by joining an existing wireless network. What's the difference between that and extending it? By extending it I loose my ability to use the ethernet to connect to internet on my Mac Pro. Odd thing is though when I initially used AirPort Utility to set up my AirPort Express, I went through all the options to get it configured to access my existing network and I checked option to allow internet access through ethernet. All is well, but then I still don't have access to the internet through the ethernet and I noticed that the setting is on Extended. Just curious why it would give me the option to use the ethernet, set it on extended and not even work.

When "joining a network," the AirPort Express Base Station (AX) acts just like any other wireless client (laptop, desktop, printer, etc.) You would want to configure the AX to join a network when you only want to use it to share a USB printer and/or stream iTunes.
When "extending a network," the AX can perform as either a main, relay, or remote base station in a Wireless Distribution System (WDS). A WDS is primarily used to extend a network wirelessly.
By extending it I loose my ability to use the ethernet to connect to internet on my Mac Pro.
If the AX is configured as either a relay/remote base station in a WDS, you actually can use it's Ethernet port for Internet access. Of course, this relay/remote must be connected to a main base station, that itself, has Internet access.

What's the difference between WDS and Extend Wireless Network?

Hi,
I have a situation where my main computer (Mac Pro) is wired to an Extreme (n), and I have an Express (n) in another room in the house to Bridge to other computers for better wireless reception.
The manuals say I should be connecting the wireless computer via WDS. The way I have it connected right now is as such.
Extreme:
Create a wireless network
Allow this network to be extended is checked
Express:
Extend a wireless network
Allow wireless clients is checked
Is the above method correct, or should I be setting the Extreme and Express via: Participate in a WDS network?
Any help would be appreciated.
Thanks!

I am not an expert on wireless networks but here is what they do in a nut shell:
WDS is a network composed by access points that work together to expand your network without the need of "wired" connectivity. so one of the bases will be wired, the rest are not , they just relay info to other computers... good for small to medium size business / homes
EWN is a network composed of wired & wireless networks/access points that work together to expand your network. pretty much you could have 5+ bases plugged in to a LAN / WAN covering different areas of your company / home (long range for medium / big business / Bill Gate's home, etc.).

Difference between "joining" and "extending"

Just added an airport express to my time capsule network. I realise that if I use the AEx to "extend" my network then the time capsule is relegated to 802.11b/g and not n.
Is the same true if I just "join" the AEx to the network and use it for iTunes and remote speakers?

Good news! That is not true. 802.11n offers the "extend" feature only between 802.11m base stations.
If you use WDS you get the same functionality but you are forced to 802.11g.
Is the same true if I just "join" the AEx to the network and use it for iTunes and remote speakers?
When the AirPort Express (AX) is configured to join a wireless network it simply acts as just another wireless client. Therefore if the network is using 802.11n the AX will communicate using 802.11n.

What is the difference between WDS and Extending a network?

What is the difference between the two? Why choose one over the other?

Both the WDS and "Extend a wireless network setting will add more coverage area to a wireless network.
WDS must be used if any device on the network is an older "g" device. The downsides to WDS are that it drops the overall wireless speed down to "g" levels (even if there are other newer "n" routers on the network) and cuts the bandwidth capability of the network in half for each "remote" device that is added to the network. That's a really severe loss in performance.
"Extend a wireless network" is a newer technology that can be used only if all of the routers on the network are newer "n" capable devices. It allows full "n" speeds and imposes only a small bandwidth penalty on the network. Obviously, this is the setup to use if your devices will support the technology.

JOIN is combining factor or two data sources.
Subquery is the resultant set of datasource(s) which can be joined/compared to other data source in your main query.

Difference between implements and extends

Hi all,
what is the difference between implements and extends. i am sorry to ask this silly question, but i am new to JAVA.
Thanks
Balaji

when you extend a class, your class that you are coding inherits every method and field from the extending class. For example:
public class CustomFrame extends JFrame {
//Your class's methods will be in here, but so will all of JFrame's methods.
}You can override (most) methods from extended classes if you want them to do different things than they normally do. The most commonly overriden methods when using swing are stuff like paint(Graphics g). It needs to be overriden to repaint all of the components.
When you imlpement something, you have to specify an interface. Interfaces have methods in them with no code. If you implement an interface, all methods in in must be defined. If not, the code will not compile. Some interfaces like ActionListener extend other classes to perform stuff. The actionPerformed(ActionEvent e) method will perform an action when a button is pressed, etc.

Difference between Implement and Extend

what is the difference between implements and extends and why do we use them
thanks,

classes extend one other class and implement as many
interfaces as they wish.
interfaces extend as many interfaces as they wish.But for all that, they both just mean "inherits."
There wouldn't even have to be two different words, since you never have a choice between X extends Y and X implements Y. For a given X and Y, only one of the two will be legal.

Whats the difference between implements and extends!??

Can an interface be extended or not??
If it can whats the difference between implements and extends??
Thank you!

Code Sample:
interface a implements aa{This is illegal. An interface cannot implement another interface. It can only extend another interface.
interface a extends aa{That's the way to do it. As already said above:
An interface can only extend another interface.
A class can extend another class.
A class can implement zero or more interfaces.
So, "implements" is only used for classes that implement interfaces. For the rest, "extends" is used.

What is the difference between Classic and Extended Withholding Tax

Hi,
Can some please tell me what is the difference between Classic Withholding and Extended Withholding Tax. How can I look at the Withholding Tax deducted from a particular invoice?

Dear Prem,
Withholding tax is the basically a tax withheld during the Vendor payment. So when making the payment to vendor the amount will be deduct (i.e withheld tax)
from the invoice and paid. The customer is actually the tax to tax authorities.

Any difference between new and old wireless Mighty Mouse?

Hello,
I got an "old" wireless Mighty Mouse (the one with the grey side buttons) from my father. Now I am wondering if there is any difference between this mouse and the new one, besides the color change of the side buttons. I checked my mouse against the tech specs on the Apple Mighty Mouse site, and they seem to be absolutely identical, but still, I would like to hear this from an expert, which I hope to find here . Also, does anyone know where to find the user’s guide for the wireless mouse online? I have been searching the whole Apple site, but found it nowhere.
Thanks in advance for your answers.

Hi,
This question is already discussed in sdn earlier.

SOLUTION TO Time Capsule and extend wireless network using AEBS, Printers..

Hello GUYS
I find the solution: at least I have extended wireless using TC and old AEBS.
: well everybody have same problems to initialize second AEBS, and set it up.
OK follow this steps:
put next to each other TC (time capsule) and AEBS (airport extreme) -> switch AEBS off
If you followed installation TC correctly it should work without any problem.
SETING UP TC PART 1
pres in finder Command + Shift + U =then click Airport utility
set your TC with manual.
On piece of paper record Airport ID:
Click on TIME CAPSULE
I recommend change name not to use deffault long name for TC. Simply call it TC if you want. Set password.
In wireless. Write a name of your Network, keep it simple TC627 what ever. Write it down on paper. security WPA2 personal and password.
Update. and close utility
End of part 1
Part 2:
AEBS setup.
Switch AEBS on: No need to switch off TC
Press reset button for more than 5 sec. so everything is restore to factory settings.
-> in the bar top click wireless and select AEBS. You have to do this otherwise Airport utility will not recognise AEBS.
When you are done. Command shift U
Click airport utility. and manual setup.
-> write down the Airport ID.
Set up your AEBS, name something simple so you know what it is. Password and security.
Here do yourself favor use the same passwords as on TC and security.
NOW ->
click Wireless.
*Wireless network has to be same as on TC.*( it is on the paper)
Select Participate in wireless network
Radio mode b,g compatible or only N it is up to you.
I setup WPA2Personal again with the same password( same on TC)
Click WDS
Select WDS remote
select Allow wireless clients
and now write the TC airport ID into WDS main: number (it is on your paper)
Update.
switch off utility.
no go to right top and change airport back to TC.
Go to manual
Click Wireless:
Select Participate in WDS Network
Click WDS: wds mode to Main
allow wireless clients: and write into WDS remotes AEBS ID, (it is on the paper).
and update.
both airports will restart.
and you are extended.
You made it. Go to Utility Cmd,shift, U and you should be able to see both airports.
Now what you have to do is to take AEBS to different place.
Put it somewhere in second room. Go back to your computer. Leave it for couple of minutes. 10 -15 is ok.
to make sure your TC can find AEBS. If not TC will indicate by flashing green and orange. = >AEBS has to be closer.
correct is that TC has still green light.
Before you start with time machine: read what files to include
hope it helps.

Could someone please help with two differences between CS and CS4?

Hello, I just moved from Photoshop CS to CS4 and have a couple of questions regarding some differences I'm seeing in the two versions.
(1) When opening files, I'm used to them opening in a smaller view as individual windows. CS4 opens all images in the expanded view. Is there a way to prevent this from happening? I create massive sports photo galleries (often more than 100 images) and usually open 25-30 images at a time, then minimize all images and work on them one at a time in chronological order. The was CS4 opens these images in full screen mode, it prevents me from doing this in a timely manner - PS never opens a group of photos up in a true chrono order. It misplaces the first image to the end.
(2) In CS, I used to be able to Right-Mouse-Click on the image's title bar to change Image and Canvas sizes. Any way to get this to work in CS4? CTL+ALT and either I or C is a three-key process and takes considerably longer than right clicking my mouse and choosing the correct option.
Thanks for any help you can provide. And apologies for being such a newbie to the latest and greatest Photoshop version. I've been living in CS for years
Mike

You are a life saver. Thanks! I looked in the INTERFACE area about three times and never understood that TABBED meant that it was opening them full screen.
Any idea how to deal with question #2? Cannot set up an ACTION for this as the action makes me have to choose an image size. I just want to have the Image or Canvas size windows open with one click, rather than holding down three keys.
Thanks again. You have been rewarded with a CORRECT ANSWER click
Mike

Difference between INSERT and EXTEND in OBPM Arrays

Hi all,
I wanted to know the diference between the EXTEND keyword and INSERT keyword while using OBPM arrays.
For e.g. if testArray is an Array then:-
What does testArray.insert mean?
And
What does testArray.extend mean?

Extend inserts at the end of the array. Insert allows you to specify an index into the array where you want to insert to.

Difference between 04W3844 and 04X6007 wireless cards for W540

I pulled these off the PDF linked here on supported cards. But I dont get which one to get. All I see is Indonesia SKU on one and Wake on the other, not sure what that means, cant find anything on this either.PDF - W540 Parts list 04W3844 1 Intel Wilkins Peak 2 7260 2*2 11ac+BT4.0 M.2 Card Indonesia SKU
04X6007 1 Intel Wilkins Peak 2 7260 2*2 11ac+BT4.0 M.2 Card Wake Does it matter which one to pick? I dont want to get the wrong one. I need dual band, my IT dept only ordered it with the single band. Id also like the AC as my home is setup for that as well. Dixit

Hello,
From looking at the descriptions in the SKUs, my best guess is that one card is specific to the Indonesian market (probably blocks some radio frequencies used by the government), while the other is for global use.
