2 theoretical questions about WDDM driver and directx

Hello

1. I tried to understand the difference between the video card driver and driver microsoft WDDM.  I know that WDDM driver is downloaded during the update, and video card driver is just video card driver is.   But what exactly is the difference between this 2 drivers? you need both to operate the computer corectly, is that each driver has a function for the satisfaction?

2. I know that x wil direct automatically updated with service packs and the new version of windows.  I also advise to upgrade for windows 8 or 7 who can tell you if your system is compatible or not.  but my question here is an old video card can support the new directx versions or the video card needs to be upgraded too to support directx 12 for example?

Thank you

Johan

WDDM is a architecture (some details in the link below), and I think that is what generates the weak base
Resolution Windows desktop when no graphcis driver is installed, but there is also a generic
Windows graphic driver.
While always a basic graphics driver, this driver allows to use the full resolution and run Windows
When no drivers are installed for your processor graphcis.
This driver installs with Windows and needs to be reinstalled automatically when you restart if you
uninstall the graphics drivers.
In this case, you would initially start in Windows mode low resolution and see a pop up
stating something to the effect that Windows installs graphics drivers.
Sometimes, people confuse it with drivers for their graphics processor.

http://en.Wikipedia.org/wiki/Windows_Display_Driver_Model

'Optional' Windows updates will offer to update the drivers for your graphics processor, but
It is not recommended, especially if you play games or do other graphics intensive.
If it is better to download graphics drivers from the mfg of the graphics card, if you use a laptop,.
the Mfg of the laptop.
Uninstall the drivers via programs and features and install the new drivers after reboot.

    Sorry but I don't understand what's your problem now. On the Toshiba support page you can find the driver NVIDIA V 43.36 for WXP (listed for Satellite 5200 903). Am I wrong? If you have installed this driver for the graphics card must be properly recognized and listed in the Device Manager.

    So now, I have to ask you once again: what exactly is the problem with display driver?

    Yes, according to iCloud Drive FAQ - Apple Support:

    You cannot use iCloud Drive on your devices until you update your iPhone, iPad and iPod touch to the latest version of iOSand your Mac to the latest version of Mac OS X. If you already upgraded and you need to use a device that does not support iCloud by car, you can still work on your documents locally, but they will not be aware of the documents on your devices up to date, or on iCloud.com.

    In addition, the system requirements for iCloud - Apple Support should be useful.

  • A question about the methods and parameters.

    Hey guys, this is my first post here. I am very new to Java and done a bit of C++ before Java. I had a question about the methods and parameters. I do not understand the methods; I know they can be repeated when it is called, but it's almost everything. I also know that a program should have a class that contains the main method. What I really, really understand on methods is what the parameters are. I know they are in parentheses and that is it. Could you explain what they are? I really appreciate it. Thanks to all in advance. Best regards, Michael

    Taking an example:
    Suppose you calculate area of the rectangle you need two inputs one is the length and the width. Area = l X b, where l = length, b = width

    If your method, say, calculateAreaOfRectangle (length int, int width) will be two parameters as arguments.

    System.out.println ("field of rectangle:" + calculateAreaOfRectangle (40,30);)

    public int calculateAreaOfRectangle (int length, int width) {}
    int area;
    Area = length * width;
    return of area;
    }

    So if you call this method then the output will be returned in 120.

    Parameters of a method are simply the input variables for the method of treatment for all calculations or something useful.

    And we cannot have methods inside the main method in Java. It is in the java syntax and if you do, it will throw a syntax error.

  • Question about the interruptions and priming

    Hello

    I had a few questions about the startup and interruptions in a virtualized environment

    Assuming that, plenty of virtualization (no material assistance to virtualization of memory ).

    1 initialization: in an ordinary PC, the boot process starts with the BIOS, to expansion ROM, back to the BIOS and MBR secondary boot record, then grub (is it) and finally the operating system. In a virtualized environment with VMM running directly on top of hardware (Native VMM), how is the initialization of the different process, as I understand it takes BIOS-> Expansion ROM - > BIOS-MBR-> other record secondary-> VMM-> OS--> applications >. Am I right on that?

    2 breaks: VMM examines the source interruptions prior to the interruption, so in a multicore environment, assuming a 2 processor core, how the VMM decides on the kernel for which the interruption in intended, prior to shipment of the interruption. Interruptions are tag ID, said core ID?

    Thanks in advance

Am I right on that?

    It is simplistic but essentially correct.  A metaphor would be a little better thinking that the hypervisor/vmm is an operating system, except that the process on this operating system are requests or comments OSes.  If the BIOS-> OPROM-> BIOS-> MBR-> hypervisor-> init process of the hypervisor-> reviews of fork () s operating systems.  This can become blurred by the design choices (for example Xen/Hyper-V init start a coded parent hard partition that makes hypercalls privileged to fork() guest OSes; ESXi init runs a very limited subset of applications directly on the hypervisor and ESX Classic is somewhere between these approaches).

    There is a subtle distinction between "hypervisor" and "www."  The "hypervisor" is the operating system of single root (e.g. ESX) who interacts directly with the hardware and has access to everything; a hypervisor is not to be used to run virtual machines.  When we talk about a "hypervisor", the tendency is to describe something which is a BONE (although usually a minimal OS designed only to run virtual machines).  The "www" is the layer that allows a virtual machine run: it provides the interposition, virtualization and emulation services and can be plural (for example a vmm by guest operating system).  Architecture of VMware deal with these two separate components, while most other virtualization platforms merge the two.

    Strictly speaking, the interruption is not transmitted to a guest operating system - receives the hypervisor (or rather the VMM it transmits to the hypervisor), the hypervisor drivers interpret the interruption (for example reading package of NIC, I/O process of HBA, the timer tick completion), then after a new appropriate break in the guest OS.

  • Satellite A60-131: Question about upgrade RAM and HARD drive

    I have a Toshiba Satellite A60 S-131, bought 2 years ago.
    I want to know is it possible for me to upgrade (internal) for a superior ability to HDD 40 GB HARD drive and update my RAM to 512 MB on the rise.

    Also I already inserted a 256 MB DDR RAM in the empty memory slot almost 1 year ago.

    Help will be appreciated.

    Hi Pranjal,

    You can definitley upgrade your hard drive for a larger version. You should find that a 80 or 100 GB will work fine. You should make sure that you get you a new disc with the same physical characteristics as you existing. The following link will help you remove the hard drive.
    http://irisvista.com/tech/laptops/ToshibaA65/satA65_1.htm

    You can also get a new hard drive with a more rapid rotation speed (5400 RPM or 7200 RPM).

    I think that the maximum RAM for the A60 is 1.25 GB which includes 1 X fixed module (I presume yours is 256 MB, which means that you can install an additional module with a capacity up to 1 GB. Available in capacities of 256 MB, 512 MB and 1 GB of RAM modules.

    Kind regards

  • Question about hard drive storage on Satellite Pro L40

    I have a Satellite Pro L40. Memory hard drive seems to be divided into two (about 35 GB each) under Vista C and e of data.
    Vista C is almost full. How can I use/access the E-data memory?

    Hi Bart

    Please don't get me wrong, but your question is really strange. I mean after reading your post, I'm really interested in your PC knowledge and how long you use your laptop.

    You want to know is basic stuff and must be learned first when you start using computers.
    When you have the time to try to get some book on WXP or Vista and all know about operating systems and how to use them.

    Open Windows Explorer, and you will have direct access to the second partition. You can move files from C to D, or save all data directly on the D partition.

    Google a bit. You can find many Web pages on basic stuff to the use of operating system.

  • Question about hard drive Partitions

    My Satellite C650 bought recently has two equal size partitions - C (called Windows) and D (known as data). However, my "Users" folder and so all my data is stored on the C drive (with all programs) while the D drive and has only the HDD Recovery inside folder. This means that I have access to half of my total disk space.

    How to move my file 'Users' the D drive - and if I do - it somehow it is interfering with the HARD drive folder?
    This can be as simple as move the users folder - but I'm not sure if the installation of 'Libraries' or all Office programs will always seek on the C drive for data.

    I would like some advice before as I did try.

    >... While the D drive has only the HDD Recovery inside folder. This means that I have access to half of my total disk space.
    That s not the truth. You can use the free space on the second partition. HDDrecovery is just a folder where recovery image is saved. You can enter the folder properties and set it as invisible and you will see it.

    This recovery is important for two things:
    -for the creation of recovery DVDs
    -for HARD drive recovery procedure.

    Generally speaking, if you have created recovery DVD (highly recommended) you can delete this folder, but after doing this, you will not be able to create recovery DVDs or of the installation of recovery disk (F8 at startup).

    You have to understand how it works?
    If you have any other questions please let me know.

  • Question about Dell backup and recovery Premium

    Always looking for a conventional way to save the Tablet (5130) and have the ability to start in an environment of recovery and restore from a backup. Did anyone tried B & R Premium? Supposedly will do exactly that... Anyone can shed some light? Thank you

    Personally, I wouldn't. I'm sure it works fine, but Vista and Windows 7 recovery options are always in Windows 8.1.

    You can perform a recovery USB flash drive to reset your device to factory (out of the box) standard in Windows. (A 8 GB flash drive works.)

    You can save an image of the entire system of external storage such as a USB 100 GB HDD or more.

    USB recovery installs a Windows recovery with multiple options environment. These include repair the disk image partition recovery on the Flash DRIVE itself or the hard disk recovery partition, if that partition has not been removed (to leave a space after creation of the USB flash drive - it's an option which is offered), or recreate the entire disk to a system image on an external hard drive attached.

    Boot from the work of USB flash drive made in the same way using a DVD or a CD bootable in previous versions of Windows. He gets the familiar environment of the recovery and begins asking for details on your keyboard.

    A few steps are required, and you must remember to MAKE backups (or schedule backups in Task Scheduler to make repetitive.)  Windows 8 will only create a backup on a small external hard drive (say 100 MB) and it will crush whenever a backup is performed. On a much larger hard drive, it will use up to 30% of the hard drive space and keep as much imaging system as possible, and then replaces the oldest with the most recent. In other words, you can keep multiple images on a 1 system external to you on a 100 GB external. (That would be about 300 MB of images of system on the 1 TB).

    If you want to try this (and why not, it's free, assuming you have already a flash drive and an external USB hard disk) at the start of this way.

    Create the key USB recovery flash. Charms blow and to search for the exact phrase "recovery disc". Select 'Create a recovery disk.' In the dialog box, check [] copy the recovery partition from the PC on the recovery disk"(if it is not grayed out, in other words).  Run through this process and you'll find yourself with a flash drive bootable USB able to mount a rescue environment.  (You may need to go into BIOS and set up the drive as your first boot device to test.)

    Create a system image for backup of the entire hard disk by hitting swipe in charms and by searching for the exact phrase "file history". Select "Save backup copies of your files with the historical file." This page takes a while to load. When loading, find "Backup of System Image" in the lower left corner.

    Are there disadvantages of this report to the use of the Dell premium service? There must be or they wouldn't charge it. I have not studied on this subject (because I'm old and stuck in my ways, and I stick to what works for me), but I imagine that it automates things a bit and has an element of cloud backup.  It can even happen transparently in the background. I do not know.

    In any case, Bob, I hope this helps.

  • questions about 2100 wlc and lwap connection

    Hello

    I have a few questions, I hope you can answer me.

    In fact, I have a controller connected to 3 Lwap 2100, and they are connected to the WCS. they have a static IP address.

    The distance between each point of access to more than 30 meters.

    1. the distance between the access points affect the accuracy or the stream. How can I calculate this

    2. because the APs use a static IP address, each customer should I connect to the network to add a static ip address? can I do the APs detect clients dynamically?

    I have lwapp reset guide, guide WCS configuration and configuration guide for WLC. If you have more documents or more pls share with me.

    BR

    Yamani

    Hello Ahmed,.

    Yes the distance between AP affect the wireless signal.

    to determine the best location of AP and the distance between them, as the site survey is necessary with the expert of the spectrum wireless or airmagnat...

    You can check the following links for design and RF management

    1) http://tools.cisco.com/squish/1Ea09

    2) http://tools.cisco.com/squish/51a58

    for other questions about DHCP, it is not a must that customer use static IP, you can always configure them with DHCP.

    as an extenal DHCP (like windows server), or on the WLC himself (to the title of controller-> > internal DHCP tab).

  • General question about the updates and version number

    I have a general question about versions and update.  I'm new on this and am in the deep end of learning I want.

    In vSphere web client, I see the following versions (these are exactly as the seller, he left a few months that I have screenshots in my documentation that match)

    Version - VMware ESXi, 5.1.0 1612806

    Profile - Dell (updated) ESXi - 5.1 - 799733 (A00)

    I am trying to familiarize themselves with the Update Manager and I noticed that there are a lot of patches and updates available.

    Lists of Update Manager 5 patches as "Missing" with Red x but directly above them are a list of patches with green tick indicating that "installed" - it is perhaps obvious, but im guessing 'installed' means really installed when displayed on the screen - there is an update installed, labeled "ESXI 5.1 all the update 2-' would be able to tell that it has been installed by the details of profile/version above?

    I don't think it's a big deal at this stage, but if I install all missing patches and then the details of the version/profile change in summary screen?

    I hope this makes sense.

  • Question about subjects, books and tables of contents

    I have a question about the subjects, books and tocs. I have a project that someone else created, and my task is to create a new topic and add it to the table of contents. I created the topic, but when I generate CHM project it does not appear in the table of contents. I tried to update the table of contents. What I think (I guess) could be the problem, is the 'links to the topics', when I see the links to the topics in other areas (old) they seem to have a link to the main book, but the new one is not mine. Could you help me? Thank you!!!

    It seems that you have a manual table of contents page, rather than using the table of contents of CHM.

    The toc.htm topic that you see in your list of topics is probably where you will need to add your new topic.

    If the table of contents was already populated when you inherited the project, I suspect the previous author was using it just to keep track of the topics they had added manually to the topic toc.htm - added the CHM topic in summary you did mark the column of the table of contents in the list of topics like '' Yes. '' then add to the toc.htm manual is not. Hope that makes sense.

    P.S. Just guess that it is installing what I can see in the screenshot. It is quite unusual, so I hope I'm right.

  • Questions about Failver customer and rapid failover

    have some questions about customer and quick Faiolver of Oracle Database HA failover. Before asking these questions, I want to explain my environment. Here are the details.



    -We have two physical locations called "ABC" and "PQR".
    -ABC is the main site.
    -PQR is the backup site.
    -In ABC, we have the database to Oracle RAC (11.2.0.2) with two nodes.
    -In the PQR, we have only one stand-alone server (11.2.0.2) database with ASM. This isn't a RAC.
    -Data Guard has been configured between ABC and PQR and it works as expected.
    -Please note that we have a license for Active Data Guard.
    -We have products of Oracle Identity Management to ABC and PQR and they will use the RAC database as a primary database that is in the CBA.
    -We have not yet set up a Data Guard Broker.

    We want to achieve under objectives:


    Objective 1:
    -------

    Whenever primary CARS down completely, standby database becomes a primary database AUTOMATICALLY and it should allow the read/write operation.
    I guess it's called 'Fast Failover'. Please let me know if I'm wrong.

    Issues related to the:

    -To do this, I need to set up Data Guard Broker so that this standy database becomes primary when CARS go down completely with a power outage, planned or not.
    -Let's say that CARS falls does completely, how long take Data Guard Broker do standby db as primary.
    -What the client application / which is already connected to the CARS.
    -Let's DB standby became as primary and after some time if RAC comes back, keep data automatically becomes the primary role of RAC?


    Objective 2:
    --------

    As I explained above, all products Oracle IDM and applications to speak to the RAC database, what do know only on the RAC database, which is the main. They are not aware of the pending database.

    -Whenever a client session is underway with the primary database of CARS if CARS completely falls down, we would like to wait until the client session should get transferred datbase standby without losing session information. However before that happens, standby database should become primary because the client session can perform write operations.

    -Whenever a client attempts to connect to the primary CARS and assumes that the cab is completely down, we would like to expect from any client connections should are transferred pending database.
    However before that happens, standby database should become primary because the client session can perform write operations.

    According to my knowledge, above scenarios are called "client failver." Please let me know if I'm wrong.



    Issues related to the:
    ----------

    1. Please throw some light to reach above features.
    2. According to my understanding, before customer failover happens, fast failover expected has already occurred and ensure should get the switch for the main role. I guess that all this happens thanks to timeout settings. What are those.


    Could you please help?

    Thank you

    I didn't say that clients cannot reconnect automatically when primary fails: I meant that client sessions can generally reconnect and also keep any session state.

    Yes, they can reconnect but only to keep the session state for a SELECT statement. It is also possible with Data Guard, not only in the CARS I wrote: here's a demo with 10 g
    http://uhesse.WordPress.com/2009/08/19/connect-time-failover-transparent-application-failover-for-Data-Guard/.
    What is not possible is to maintain a session state: (INSERT/UPDATE/DELETE) pending transactions must be cancelled.

  • Questions about apex_web_service.make_request and collections

    Hello

    I began using with Apex Web services, and I have a few questions about the apex_web_service.make_request procedure. You can pass a name of the collection as a parameter. I'm a little confused on this parameter from the collection...

    This is perhaps a silly question, but the documentation is not very clear, so... This procedure always inserts just a line in the collection (with the XML returned by the web service call), or are there cases where several lines will be inserted?

    If there is still only a single row, what are the practical reasons to use a collection for her? I ask because in most cases interest you about the columns/rows to display in a form or a report in the Apex and I don't see the advantage to store in a collection of single-row, but I may be missing something...

    If the response contains several rows of data, it will be automatically extract the lines and insert them into the different lines of the collection? (posts...)

    What is the best approach then to extract several rows returned in the XML response and insert them into a collection? Currently I use XMLTABLE in a loop and call apex_collection.add_member for each row returned. is there a better way to do it?

    Thank you
    Luis

    Luis,

    the webservice returns only one row in the results collection.

    XMLTABLE using is a good idea, instead of using a loop, you can also use APEX_COLLECTION. CREATE_COLLECTION_FROM_QUERY or CREATE_COLLECTION_FROM_QUERY_B (B for bulk which may mean 'fast').

    brgds,
