just purchased an Airport Extreme , what´s the difference between LAN and WAN

Check the Setup Guide for the AirPort Extreme to confirm that the WAN port accepts the signal from your modem or from another router on your network.
Other Ethernet devices on your network connect to the LAN <-> ports.

  • Why would i connect a external hardrive to the airport extreme and what is the difference between LAN and WAN gigabit ethernet?

    Hey just wanted to know what is the reason i would connect my external hardrive to the extreme and what is the difference between LAN and WAN ehternet. I know one is local and other is wide but can someone explain in simpler terms.

    Connecting a hard drive to the Airport Extreme makes it available to be shared across all the computers on your network.
    WAN (Wide Area Network) is your connection to the internet
    LAN (Local Area Network) is your internal (or local) ethernet connections (computers, printers, etc...)

  • What is the difference between express and extreme?

    I am wondering what is the difference between express and extreme and will there be any effect in performance if I am just using it at home?

    I am just looking for router that gives me reliable highspeed wi-fi for personal use within my home.
    Wireless performance is roughly equal between the two devices, with a slight edge to the Extreme since it uses a bit better antenna package.
    If I connect the the hard drive to the extreme, does that mean I can back up all my data wirelessly through the port into my external hard drive?
    Yes, if you backup manually, or use an application like Carbon Copy Cloner or SuperDuper. 
    No, if you were planning to use Apple's Time Machine application since Time Machine backups to a hard drive at the USB port of the AirPort Extreme are not officially supported by Apple.

  • What's the Difference Between OLAP and OLTP?

    HI,
    What's the difference between OLAP and OLTP ? and which one is Best?
    -Arun.M.D

    Hi,
       The big difference when designing for OLAP versus OLTP is rooted in the basics of how the tables are going to be used. I'll discuss OLTP versus OLAP in context to the design of dimensional data warehouses. However, keep in mind there are more architectural components that make up a mature, best practices data warehouse than just the dimensional data warehouse.
    Corporate Information Factory, 2nd Edition by W. H. Inmon, Claudia Imhoff, Ryan Sousa
    Building the Data Warehouse, 2nd Edition by W. H. Inmon
    With OLTP, the tables are designed to facilitate fast inserting, updating and deleting rows of information with each logical unit of work. The database design is highly normalized. Usually and at least to 3NF. Each logical unit of work in an online application will have a relatively small scope with regard to the number of tables that are referenced and/or updated. Also the online application itself handles the majority of the work for joining data to facilitate the screen functions. This means the user doesn't have to worry about traversing across large data relationship paths. A heavy dose of lookup/reference tables and much focus on referential integrity between foreign keys. The physical design of the database needs to take into considerations the need for inserting rows when deciding on physical space settings. A good book for getting a solid base understanding of modeling for OLTP is The Data Modeling Handbook: A Best-Practice Approach to Building Quality Data Models by Michael C. Reingruber, William W. Gregory.
    Example: Let's say we have a purchase oder management system. We need to be able to take orders for our customers, and we need to be able to sell many items on each order. We need to capture the store that sold the item, the customer that bought the item (and where we need to ship things and where to bill) and we need to make sure that we pull from the valid store_items to get the correct item number, description and price. Our OLTP data model will contain a CUSTOMER_MASTER, A CUSTOMER_ADDRESS_MASTER, A STORE_MASTER, AN ITEM_MASTER, AN ITEM_PRICE_MASTER, A PURCHASE_ORDER_MASTER AND A PURCHASE_ORDER_LINE_ITEM table. Then we might have a series of M:M relationships for example. An ITEM might have a different price for specific time periods for specific stores.
    With OLAP, the tables are designed to facilitate easy access to information. Today's OLAP tools make the job of developing a query very easy. However, you still want to minimize the extensiveness of the relational model in an OLAP application. Users don't have the wills and means to learn how to work through a complex maze of table relationships. So you'll design your tables with a high degree of denormalization. The most prevalent design scheme for OLAP is the Star-Schema, popularized by Ralph Kimball. The star schema has a FACT table that contains the elements of data that are used arithmatically (counting, summing, averaging, etc.) The FACT Table is surrounded by lookup tables called Dimensions. Each Dimension table provides a reference to those things that you want to analyze by. A good book to understand how to design OLAP solutions is The Data Warehouse Toolkit: Practical Techniques for Building Dimensional Data Warehouses by Ralph Kimball.
    Example: let's say we want to see some key measures about purchases. We want to know how many items and the sales amount that are purchased by what kind of customer across which stores. The FACT table will contain a column for Qty-purchased and Purchase Amount. The DIMENSION tables will include the ITEM_DESC (contains the item_id & Description), the CUSTOMER_TYPE, the STORE (Store_id & store name), and TIME (contains calendar information such as the date, the month_end_date, quarter_end_date, day_of_week, etc).

  • Looking for new laptop what are the differences between pro and air? Besides size. Does the air preform like the pro?

    Looking for new laptop what are the differences between pro and air? Besides size. Does the air preform like the pro?

    The NEW macbook Pro and Air are EXTREMELY close in form factor
    The newest macbook Pro is essentially a larger macbook Air with Retina display and options for speed in increasing prices up to an independent graphics and quad core processor.
    both Air and new Pro now have PCIe SSD and permanent RAM.
    The Air is the lightweight portable form factor, fast to boot and shut down, but with longer battery life than any of the macbook pro in 13"
    Now the new macbook Pro and macbook Air are extremely close in form factor and nature.
    both have 802ac wifi
    both have permanent RAM, no superdrive
    both are slim profiles and SSD
    The only real differences now are (in the most expensive Pros) faster processors and quadcore processors and top end model autonomous graphics.
    ....and of course the retina display
    both are now "very good for travel"
    Other than features the form factor of the Air and Pro are VERY close now,....so now its merely a matter of features and price more than anything.
    You need an external HD regardless of what you get for backups etc.   Drop into an Apple store and handle both and make your choice based on features, such as Retina or non-retina, .... both at a distance now look like the same computer.
    The Pro weighs more, ....but nowhere near what it used to just a month ago on the older macbook Pros
    The NEW macbook Pro is a different creature entirely than the older macbook Pro, .....the new Pro is thicker than the Air, but id frankly call the NEWEST Pro a "macbook Air with Retina display" , or
    Maybe a “macbook Air PRO with Retina display” 
    Instead of Air VS Pro now,.....its really a smooth transition from Air to pro without comparing say, 2 different creatures, now its like contrasting a horse from a race horse.
    Either one in 8gig of RAM (preferably)... the 4gig upgrade costs very little,  the I7 you will notice only 15% faster on heavy applications over the I5, and NOTHING on most APPS.....I5 has longer battery life.
    As you see below, the non-Retina 13" AIR is 82% of the Macbook with Retina display in resolution
    there is no magical number of pixels per inch that automatically equates to Retina quality.
    http://www.cultofmac.com/168509/why-you-might-be-disappointed-by-the-resolution- of-those-new-retina-display-macs-feature/
    A huge internal SSD isnt a game changer for anything, you need an external HD anyway
    what you WONT READ on Apple.com etc. is that the larger SSD  are MUCH FASTER due to SSD density
    "The 512GB Samsung SSD found in our 13-inch model offers roughly a 400MB/s increase in write speeds over the 128GB SanDisk/Marvell SSD"

  • What is the difference between TO_CHAR and TO_DATE()?

    Hi everybody,
    i am facing a problem in my system.It is quite urgent, can you explain me "What is the difference between TO_CHAR and TO_DATE()?".
    According to user's requirement, they need to generate a code with format "YYMRRR".
    YY = year of current year
    M = month of current month (IF M >=10 'A' ,M >=11 'B' , M >=10 'C')
    RRR = sequence number
    Example: we have table USER(USER_ID , USER_NAME , USER_CODE)
    EX: SYSDATE = "05-29-2012" MM-DD-YYYY
    IF 10
    ROW USER_ID , USER_NAME , USER_CODE
    1- UID01 , AAAAA , 125001
    2- UID02 , AAAAA , 125002
    10- UID010 , AAAAA , 12A010
    This is the original Script code. But This script runs very well at my Local. Right format. But it just happens wrong format on production.
    12A010 (Right) => 11C010 (Wrong).
    SELECT TO_CHAR(SYSDATE, 'YY') || DECODE( TO_CHAR(SYSDATE, 'MM'),'01','1', '02','2', '03','3', '04','4', '05','5', '06','6', '07','7', '08','8','09','9', '10','A', '11','B', '12','C') ||     NVL(SUBSTR(MAX(USER_CODE), 4, 3), '000') USER_CODE FROM TVC_VSL_SCH                                                       
         WHERE TO_CHAR(SYSDATE,'YY') = SUBSTR(USER_CODE,0,2)                         
         AND TO_CHAR(SYSDATE,'MM') = DECODE(SUBSTR(USER_CODE,3,1),'1','01',          
              '2','02', '3','03', '4','04', '5','05',          
              '6','06', '7','07', '8','08', '9','09',          
              'A','10', 'B','11', 'C','12')                    
    I want to know "What is the difference between TO_CHAR and TO_DATE()?".

    try to use following select
    with t as
    (select TO_CHAR(SYSDATE, 'YY') ||
             DECODE(TO_CHAR(SYSDATE, 'MM'),
                    '01', '1',

  • What's the difference between SNC and SRM?

    we will sell SNC in Q2.But i don't know what is the difference between SNC and SRM.
    i've heard SNC suit Direct procurement better than SRM...
    Pls give me the advice and information.
    good regards kenji

    Hi Kenji,
    SRM is more of Supplier Identification and SNC work of building
    relationship with Supplier starts after this Supplier identification.
    SNC is very Good tool to handover Inventory replenishemnt
    to Suppliers and it gives Visibility of inventory information over Web UI.
    SNC has many processes like PO Collaboration, SMI, DR,DCM, SNI,
    Invoice Collaboration,Release process...to accomplish above mentioned task.
    SNC is designed for direct materials procurement.
    SRM has contract negotiations,bids,auctions for sourcing to identify suppliers
    SRM is good for basic purchasing fuctionality and suitable for indirect materials.
    In addition to all these SNC has Customer Collaboration functionality also.
    Regards,
    Vasu

  • What's the difference between 2nd and 3rd generation

    PLEASE HELP! New Apple user and looking to purchase a used 2nd or 3rd generation ipod touch.
    what's the difference between 2nd and 3rd generation?
    apparently I am told that the 2nd gen does not have the capabilities of listening without headphone? and the 3rd gen does??

    Hi maximumslowness - (great name),
    The 2nd gen Touch has one internal speaker, so you can listen to it, (both left and right channels) without headphones.
    However - it's a small single speaker and it is not very loud. It's not designed for quality listening (neither is the speaker on the 3rd gen as far as I know) and probably will not be adequate if there is a lot of background noise nearby.
    One option is to drop the iPod (not literally!) into an iPod Docking station so that the sound can play out through a self-contained mains-powered amplified speaker, which will also charge your iPod. There are many on the market. On the bottom of the iPod is the 30-pin dock connector which can be used to feed the audio to a docking station. Another option is simply to use a cable to connect from the headphone socket to the audio input on any amplifier.
    Yet another is to plug in a small fold-up style speakers, such as
    http://www.amazon.co.uk/Portable-Folding-Speakers-iPods-Players/dp/B000A1QKNU/re f=sr_1_84?ie=UTF8&qid=1332326622&sr=8-84
    or http://www.amazon.co.uk/Generation-Capsule-iPhone-Laptop-Speaker/dp/B002XNO7FQ/r ef=sr_1_6?ie=UTF8&qid=1332326656&sr=8-6
    I've no idea how good the sound is, you'll have to judge that for yourself. The links are both to a UK store, but most countries will have a similar option.
    I do not recieve any form of payment or compensatiion for the above links.

    One more thing, if you do not have the hard drive icon on the desktop you can get it there by:
    click on the desktop so the menu bar says Finder next to the apple logo, click Finder, then Preferences, General, Show These Items on desktop and check the hard disks:
    That makes life a lot easier when you want to find out information.

  • What's the difference between boxing and unboxing?

    What's the difference between boxing and unboxing, I'm a bit confused?
    Is autoboxing the same as boxing?
    This is what I know so far:
    -This is boxing, i think:
    int  []arrayset = {1,2,3};but I don't understand what unboxing is, can someone explain it to me.

    I did little research, but please correct me ifI'm
    wrong:
    Is this similiar to unboxing:
    System.out.println(intArray[0] + intArray[1] +
    intArray[2]);
    Only if intArray is declared asInteger[]
    intArray ...Then the Integers at intArray[0] etc are unboxedinto
    int primitives before adding.Did you try that before you posted it? Autoboxing is
    applied only to an individual primitive/wrapper.
    Arrays and collections aren't subject to
    autoboxing/unboxing. Basically, the compiler will
    fill in constructs such as Integer.valueOf() for you,
    it doesn't go as far as generating loops and new
    arrays for you
    OP, as Peter said, the difference between boxing and
    unboxing is merely one of direction. Autoboxing wraps
    a primitive up for you, auto-unboxing extracts the
    primitive from a wrapperAm fully aware of that, the OP's example contained references to array elements but it was not clear whether that array was declared as Integer[] or int[], hence my answer.
    And just for the recordInteger[] intArray = new Integer[] {1, 2, 3}; // autoboxing
    System.out.println(intArray[1] + intArray[2]); // autounboxing
    // while ...
    int[] intArray = new int[] {1, 2, 3}; // no boxing
    System.out.println(intArray[1] + intArray[2]); // no unboxingis what i meant.

  • What's the difference between "PreparedStatement" and "Statement"?

    What's the difference between "PreparedStatement" and "Statement"?
    Which is better??????

    Read the docs for the two classes. The differences are apparent there.
    Which one is better depends on your needs. I think that constructing and executing a PreparedStatement can be a bit less performant than just a Statement, if you're only executing the query one time. But I don't think that difference will normally be noticable in the context of a given application.
    Additionally, if you have to pass any dates or strings to the query, you'll want PreparedStatement's parameters, rather than trying to format and escape things in the query string.

  • What's the difference between setFollowRedirect() and setinstanceFollowRedi

    What's the difference between setFollowRedirect() and setInstanceFollowRedirect() ?????

    Hi there,
    setFollowRedirects and setInstanceFollowRedirects both set flags that indicate whether or not the HtppURLConnection should follow a redirect if it receives one from the server that it is connecting to. The difference is that setFollowRedirects() is a static method that changes the behaviour for all instances of the HttpURLConnection class (or more likely the implementation class, HttpURLConnection is abstract) and setInstanceFollowRedirects() just changes it for the instance on which you call it.
    BTW: The field set by setFollowRedirects is private (followRedirects) while the flag set by setInstanceFollowDirects is protected and is listed in the API docs (instanceFollowRedirects)
    Hope this helps
    Amanda
