WHAT IS 802.1 MEANING? HOW CAN I CHOOSE ABOUT OPTION INSIDE BETWEEN 802.1WEP OR WPA ENTERPRISE? WHAT'S DIFFERENT?

802.11 refers to a document that specifies how wireless networking works. It goes into detail about the radio signals, frequencies, signal strengths, encoding of data, etc. From a practical standpoint, the typical person really only care about a couple of things: speed and encryption.
802.11b - describes networks that transmit 11 mbps using a 2.4 GHz radio frequency
802.11g - describes networks that transmit 54 mbps using a 2.4 GHz radio frequency
802.11n - describes networks that transmit up to 600 mbps using 2.4 GHz and 5 GHz frequencies
n is faster than g which is faster than b. The speed of a network connection is limited to the slowest part (so, if you have an 'n' router, but your laptop only supports 'g', you get the 'g' speed).
WEP, WPA, and WPA2 refer to data encryption schemes specified in parts of the 802.11 document. With Wi-Fi, you are broadcasting your network activity over a radio, and it's pretty obvious that anyone could eavesdrop on the transmission. By using cryptography, you can scramble the data being passed back and forth so that the sender and receiver still understand the messages sent, but an eavesdropper cannot.
WEP is a very simple encryption scheme, one that the methods to decrypt the data is pretty straight-forward. It's not effective against someone that wants to intentionally eavesdrop on your activities (or access your computer) because they can use software to determine the password simply enough.
WPA and WPA2 are improvements over WEP that make cracking the password even more difficult (WPA2 being better than WPA).
The "enterprise" version of WPA2 refers to a variation on WPA2 that requires special security servers, security certificates, and other complicated systems most likely only applicable to a corporate or military environment. It's impractical for a home or small office.
To connect to a wireless network, you generally don't have to worry about the encryption used since the computer will receive a notice from the wireless network about how it is setup and use the appropriate method. It's probably good for you to pay attention whether the network you are connecting to is secure or not.
If you are setting up a network at home using a cable modem or broadband router, or even just a Wi-Fi access point, you want to set it up to use WPA2 unless you have some very old computers that only support WPA. You should avoid using WEP.

  • HT5731 How can I choose an option to buy movies with captions for the hearing impaired?

    Captions for the hearing impaired. Are they available when buying from iTunes ?

    They are available, but it's the film studio that has to include them on a particular film.
    Those that have closed captioning on them have CC against them on their description pages in the store e.g.
    Whether a film has subtitles available on it should also be listed on its descrition page e.g. (from a different film to the above CC film) :

  • How can I change view options for ALL playlists?

    How can I change view options for ALL playlists? With one single click or trick?
    I have a lot playlists and don't want to change every single one of them separatly.
    Thanks for your help. (I use Windows 7)

    There's no FAST way I know of, which is what I think you mean.
    Only the painful SLOW way of one-by-one.
    You could make a new playlist from the main library after you've set the columns up as you like.
    Go to an existing playlist that doesn't have the columns you want, and select all.
    RIght-click > Add to Playlist and send them to the new playlist.
    That's still one-by-one and only works with static playlists, not smart ones.

  • How can I make a server differ between two or more clients?

    How can I make a server differ between two or more clients?
    The clients can connect and talk to the server fine, but how can I make the server talk to one, two or all clients? i.e. what would be a good way to implement this?
    Currently, the server listens for connections like this:
    while (listening) {
    try {
    new ServerThread(this, serverSocket.accept()).start();
    I guess one way would be to add the ServerThreads to a Hashtable with the client ID as key, and then get the ServerThread with the proper client ID, but this seems unnecessary complicated. Any ideas?

    Complicated was perhaps the wrong word, I should have
    written something like it doesn't "feel" right. Or is
    this a common and good way to solve communication
    between a server and multiple clients?Thats pretty much how I do it. I normally use an array or ArrayList of Sockets instead of HashTable, with [0] being the first player etc.... Then you can communicate with exactly who you want. If you want to send bytes to all of them, just send the same thing to each socket individually (or is there a better way to do this?).

  • I just recently purchased a mini iPad for my child. It was set up in the Apple store with my Apple id. I now want to create an Apple id for my child and switch it over, how can I go about that. I already downloaded some of the games from my account.

    With a new account, you'll need to rebuy the games.
    Each user should have their own icloud account, otherwise they end up getting the same emails, contacts, calendars, notes, reminders, etc. - usually not what you want.  But if all have been sharing the same itunes ID, keep it that way, you can have different IDs for itunes and icloud.
    If you already have another icloud account, and want to set it up on a device, then go to Settings>icloud, scroll to bottom of screen and tap Delete Account.  This only disconnects the device from that account, no data is lost on icloud.  Then enter the account ID that you want to use.

  • How can I share a static field between 2 class loaders?

    Hi,
    I've been googling for 2 days and it now seems I'm not understanding something because nobody seems to have my problem. Please, somebody tell me if I'm crazy.
    The system's architecture:
    I've got a web application running in a SunOne server. The app uses Struts for the MVC part and Spring to deal with business services and DAOs.
    Beside the web app, beyond the application context, but in the same physical server, there are some processes, kind of batch processes that update tables and that kind of stuff, that run once a day. Theese processes are plain Java classes, with a main method, that are executed from ".sh" scripts with the "java" command.
    What do I need to do?
    "Simple". I need one of those Java processes to use one of the web app's service. This service has some DAOs injected by Spring. And the service itself is a bean defined in the Spring configuration file.
    The solution is made-up of 2 parts:
    1. I created a class, in the web app, with a static method that returns any bean defined in the Spring configuration file, or in other words, any bean in the application context. In my case, this method returns the service I need.
    public class SpringApplicationContext implements ApplicationContextAware {
         private static ApplicationContext appContext;
         public void setApplicationContext(ApplicationContext context) throws BeansException {
              appContext = context;
         public static Object getBean(String nombreBean) {
              return appContext.getBean(nombreBean);
    }The ApplicationContext is injected to the class by Spring through the setApplicationContext method. This is set in the Spring configuration file.
    Well, this works fine if I call the getBean method from any class in the web app. But that's not what I need. I need to get a bean from outside the web app. From the "Java batch process".
    2. Why doesn't it work from outside the web app? Because when I call getBean from the process outside the web app, a different class loader is executed to load the SpringApplicationContext class. Thus, the static field appContext is null. Am I right?
    So, the question I need you to please answer me, the question I didn't find in Google:
    How can I share the static field between the 2 class loaders?
    If I can't, how can I load the SpringApplicationContext class, from the "Java batch process", with the same class loader my web app was started?
    Or, do I need to load the SpringApplicationContext class again? Can't I use, from the process, the class already loaded by my web app?
    I' sorry about my so extensive post...
    Thank you very much!

    But maybe, if the web service stuff gets to complicated or it doesn't fulfill my needs, I'll set up a separate Spring context, that gets loaded everytime I run the "Java batch process". It'll have it's own Spring configuration files (these will be a fragment of the web app's config files), where I'll define only the beans I need to use, say the service and the 2 DAOs, and also the DB connection. Additionally, I'll set the classpath to use the beans classes of the web app. Thus, if the service and DAOs were modified in the app server, the process would load the modified classes in the following execution.You'll almost certainly have to do that even if you do use RMI, Web services etc. to connect.
    What I suggest is that you split your web project into two source trees, the stuff that relates strictly to the web front end and the code which will be shared with the batch. The latter can then be treated as a library used by both the batch and web projects. That can include splitting Spring configuration files into common and specific, the common beans file can be retrieved from the classpath with an include. I regularly split web projects this way anyway, it helps impose decoupling between View/Controller and Model layers.
    On the other hand, you might consider running these batch processes inside the web server on background threads.

  • How can I choose another name for Game Center? (not a nick)

    How can I choose another name for Game Center ? (not a nick)

    Hi XxCarrisxX,
    I apologize, I'm a bit unclear on exactly what you are asking. If you are talking about changing to or using a different Apple ID in Game Center, you may find the following article helpful:
    Sign in to your Game Center account using your Apple ID. If you don't have an Apple ID or another Apple account, tap or click Create New Account to create an account to use with Game Center.
    You can change the account you are signed into by:
    iOS: Tap Settings > Game Center.
    OS X: Click the Me tab in the Game Center app and click on your Account.
    Apple Support: Using Game Center
    http://support.apple.com/kb/ht4314
    However, make sure you are aware of the following:
    Note: Please note each Apple ID has its own associated scores, achievements, and friends.
    Apple IDs are also tied to your other Apple services, and therefore should not be created lightly.
    Regards,

  • How can I insert a vertical line  between two underlined unfilled with text lines.  I am trying to construct an invoice and I need a break.  If I try any of the shapes or inset functions it eliminates my underlined lines and shifts the whole document.

    I am trying to construct an invoice.  How can I install a vertical line between two or more underlined lines to create a break.  I have tried the insert, shapes and nothing works.  If I try any of the functions the whole document shifts to the right and I loose some of the lines.  Is there a work around, or is I work not able to do what I want?   
    Thanks
    Armand

    It sounds as though you may have "Object Causes Wrap" activated for the Line Shape. This will push other content away.
    See the Wrap Inspector.

    Hello there - how can I share my iTunes library between two users on the same computer? I put the library in a shared folder between both and have selected this library on both as well, but when I update iTunes with music etc it only appears on one?

    Thank you Joe - I tried this but it's only showing a teensy amount of music - the stuff on the second users account as opposed to the giagntic library on the 'main' account. I actually went to a Genius Bar and they said that apple doesn't really want you to share music between accounts - parents don't want to hear their kids music etc. Which seemed strange, but it might be the case sadly   Thanks anyway!

    Can any one suggest me how can I use relative path inside SSIS pacakge to access config file ? Please help me as its urgent.THanks for your help in advance.

    Hi Jay,
    SSIS can only recognize the absolute path of a XML Configuration file, the relative path is not supported. Furthermore, if the XML Configuration file is already generated, we can use the Environment variable package configuration type instead so that
    SSIS runtime automatically looks for the configuration file from the path defined in the environment variable. This is convenient when we need to deploy a package to different environment. We only need to define the environment variable for package configurations
    once on each server, and then the variable can be used by all the packages on this server.
