Who is at home, set up a network would like to, is often faced with the choice between DLAN and Wi-Fi. Our comparison shows that, in what both of these methods differ from each other.

DLAN: Internet from the wall socket

DLAN Adapter to the power outlet DLAN Adapter to the power outlet When DLAN (abbreviation for direct LAN) is the power line to Transmit the data will be used. The connection with the computer through a socket adapter and a LAN cable.

Facilities: The DLAN set-up is relatively easy. For this you need at least two adapters, one of which is directly connected to the Router. The prices for two DLAN Adapter begin in the Online trading at around 30 Euro.
Range: The maximum DLAN range is 300 meters. It is significantly higher than the range of a wireless network. Theoretically, with the appropriate adapters, a transmission Speed of up to 600 Mbps. Disturbances in the power grid can speed up, however, significantly reduce.
Suitable for: DLAN is suitable especially for households, in which a Wi-Fi Signal by factors slowed or interrupted. In a DLAN falls in addition, no radiation.
Security: The DLAN Signal can be encrypted so that no one is Unauthorized your Internet use or spying. This is usually a 128-Bit AES encryption is used.

Wi-Fi: Wireless Internet

Wireless Router: Wireless Internet Wi-Fi Router: Wireless Internet on a wireless network is the network signal wirelessly transmitted to and from compatible devices receive.

Facilities: For setting up a wireless network you will need a suitable Router, you are in the Online trading already from around 15 Euro. The setup usually takes a little longer than the one DLANs, because the Router via a Software needs to be configured.
Range: The Wi-Fi range varies from device to device, but is usually within buildings between 30 and 50 meters. The maximum speed in the 2.4-GHz frequency range is 600 MBit/s.
Suitable for: The Wi-Fi radiation is controversial among experts and it is not final is investigating whether you have negative health effects. The expert opinions will continue to be apart. In a WLAN, you can not only with Laptops and Desktop PCs with the corresponding network card to dial, but also with mobile devices such as Smartphones and Tablets.
Security: Through the Router Software you can use your Wi-Fi encrypt to the security of the network.

Conclusion: DLAN or WLAN?

The establishment of a Wi-Fi network is usually cheaper, but requires a bit more time for the configuration. What is important in the choice between DLAN and Wi-Fi Internet, especially the spatial Situation: walls, walls and Ceilings can a wireless Signal to significantly weaken, so that a DLAN may make more sense would be. On the other hand, due to disturbances in the Transmission across the grid is almost never the complete speed in all the DLAN network connected devices. It is also a compromise between the two variants. Thus, there are about DLAN Adapter with integrated Wi-Fi, at the same time, a cable as well as a wireless connection.

This must, of course, an LTE connection with possible large volumes of data have booked and for the Router, about 150 euros.
Wireless & rechargeable battery: with The Wi-Fi Standard, the manufacturer mostly on 802.11g, so that you can achieve data rates of up to 54 MBit/s gross get - passable. Only a few mobile Hotspot Router such as the MF91D of ZTE already support 802.11n, but these remain with 72 MBit/s far below the Maximum capacity of 600 MBit/s (this saves for electricity). The battery performance is relatively weak and limited to a few hours.
Pay attention to the Gerätezahl: Depending on the performance of the mobile Wi-Fi Hotspots, you can use many devices at the same time surfing. When Huawei E5776 are up to ten devices; when, with about 50 euros cheaper Huawei E5331 at least eight devices. For comparison: The mobile USB dongle Huawei E355 serves five devices with its Internet connection for about 59 euros.
Differences in the operation: The most mobile Hotspots can be like a "normal" Router via the web interface on the PC set up and control.

If the PC is booting beeps, each error message is a meaning of its own. We will show you how to interpret the signals.

If the Computer beeps ...
...and not properly boots up, you can use the sounds to find where the Defect is found. When you Start checking the Bios (Basic Input / Output System), all built-in Hardware. The error messages are not uniform, each Bios has its own error Code. Therefore, we declare to you in this Tip, how to get the most Beep-beeps decrypt and what they mean. What Bios you have, you will see at the Start shortly displayed in the top left.

AMI-BIOS - acoustic error Codes
A long beep at startup, this means that at AMI BIOS that everything is in order and now the operating system can be started. A Dauerpiepen at the Start indicates an error on the power supply. However, before you buy a new one, turn off the Computer and try another Start.

1 x short: your Computer Beeps at boot with an AMI BIOS once, sits a RAM either not right in his Bank, modules in pairs do not match, or a RAM is defective. As a first step, you should verify that the RAM firmly into the Slot is locked so is seated properly.
2 x short or 3 x just means a Parity Error in the first 64kB of memory, i.e. one of the Hardwaretestroutinen is flawed. Check the RAM.
4 x brief likewise points to a failure in the first 64 kB of memory. Either the battery is defective or you need a new Mainboard. Check in but also the RAM settings.
5 x brief: this is a Defect with the processor. This can be insufficient cooling, or the processor is to be highly synchronised.
6 x brief: This Sequence is referred to a Gate A2O error. Usually this is a broken keyboard is the cause for the error message. < Try a different keyboard to the Computer.
7 x brief: The message tells you that the processor is a Ausnahmeinterrupt produced. Either is a Kontaktproblem with the Socket or the processor is overclocked.
8 x brief: This error Code indicates that the Bios of the video card not found. Either she will not sit properly in the Slot, or it is defective. This error message is the same procedure as the RAM: Check the proper seat of the video card, and if they are fixed in the Slot is fully engaged.
9 x briefly points to a ROM Bios checksum-error. The BIOS can be corrupted or not properly updated.
10 x short: CMOS can not be read. The motherboard is defective, it remains only to the exchange.
11 x brief: the Computer at startup, as many notes in a row, he wants you to say that a checksum Error has occurred. That sounds worse than it is. It means that the CMOS battery is empty. In the CMOS memory are all customized settings to Start stored. The battery is empty, you must either awkward at every Start of the settings in the Bios, by Hand, make selections, or simply the CMOS battery switch.
3 x short, 3 x long, 3 x briefly: It is only the exchange of memory - it is defective.
1 x long, 1 short: This error message indicates a serious error on the server Board. This can, for example, an incorrect clock speed of the CPU.
1 x long, 2 short: The PC will find the graphics card is not.

Phoenix BIOS and its Beep-beeps
The Phoenix Bios brings his messages, not as a combination of short and long tones, but only as a brief, broken intervals. 1-1-3: means a CMOS read/Write errors. To fix, you should use the BIOS Setup to run.

1-1-4: a BIOS checksum-error, you can select the BIOS replacing or updating.
1-2-1, 1-2-2, 1-2-3: If one of these strings, the DMA controller or the Systemtimer defective. You need a new Board.
1-3-3, 1-3-4, 1-4-1, 1-4-2: Check to see if the RAM is correctly seated and Slot are engaged.
3-1-1, 3-1-2, 3-1-3, 3-1-4: These beeps have you all as Defects in different registers interpret. All you have only a new Motherboard installed.
3-2-4: the keyboard controller registers a Defect. Here, too, you may need the Board to replace.
3-3-4, 3-4-1, 3-4-2: These sequences have with the video card to do. Either there is a damage to the card or on the memory before or you have the cable is not connected properly.
4-2-1, 4-2-2, 4-2-3, 4-2-4: There are problems with the Timer Interrupt, the Shutdown function, an error Gate A20 or an unexpected Interrupt in Protected Mode. Also here is the exchange of the Board as a solution of the problem.
4-3-1: The PC reports DRAM error. Check the proper seat of the DRAM.
4-3-2, 4-3-4: Now it's either the Timer is defective, or there is a Problem when Testing the real-time clock. Definitely would like them to the PC in order to say that a new Board need.
4-4-1: A serial interface has failed the Test. You can use in the BIOS, turn off and an interface card install 4-4-2: A parallel interface is the Test failed. Also in this case, you have the switch-Off in the BIOS and the installation of an interface card.
4-4-3: This error means the failed Test of a Co-processor. Replace him, if he socketed.

Award BIOS and its error messages
You have an Award BIOS, it should Start one short beep. Then you can relax and sit back, it's all right. A continuous tone or a short, repeated tone means a failure in the power supply to the motherboard. Mostly it's the memory or on the graphic.

2 x short: A video error. As you with this message, proceed, you will be displayed on the screen.
1 x long, 1 short: The RAM is faulty or not properly seated in the Socket.
1 x long, 2 short: This String tells you that the graphics card is broken, or maybe just not seated properly.
1 x long, 3 x short or 3 x length: here is something wrong with the keyboard not. Is a Defect or is not connected properly?

How many pixels you have to endure, there is a Pixelfehlerklasse price. The industry has the Pixelfehlerklasse II to a Standard. Most of TFT-monitors conform to this.

In this class, you need per 1 Million pixels total of 2 continuously lit pixels, 2 black pixels and up to 5 defect Subpixel to accept.

A shockingly high value, because they usually already have a Pixel extremely noticeable and distracting. In fact, however, you need 4 defective pixels and 5 defective Subpixel accept, before you have options.

Does this not a guarantee?

Many manufacturers close pixel errors aware of the warranty, since few defective pixels due to the production of which is not unusual.

You can get only from a certain amount of defective pixels with their claims to enforce. With a single defective pixels, however, they have no real Chance. Try here a fair solution.

Tips and facts:

A Monitor with a resolution of 1920 x 1080 has over 2 million pixels, the defect can be.
Hot pixels are called defective pixels, the permanent colour display.
Stuck Pixels are called defective pixels, which is always a false color view.
A Dead Pixel is the name for a black and thus dead pixels.
Dead pixels can usually not repair.

When buying on the class of the monitor. The smaller the class, the less defective pixels are allowed. Standard class II.

Macbook-Air-or-Pro-the-most-important-differences

Macbook Air or Pro - the difference between the two Apple notebook is not only the name. Read in this comparison, what are the similarities and differences of the two laptops and for whom which model is.

The Display
Macbooks with Retina-Screen Macbooks with Retina-Screen Both the Macbook Air as well as the Macbook Pro are available in multiple sizes and Processor timings available. With a screen size of 11.6" is the Macbook Air ultramobil and easily in your briefcase, messenger bag or backpack store, while the Macbook Pro with a screen size 15.4" as Desktop replacement serve; Apple offers even a model with a 17-inch screen size, but also with hefty 3000 Euro effect. The 13 - or. 15-inch-Per-Macbooks are available in a cheaper variant with "normal" Display as well as in (which is also expensive) High-End configuration with ultrascharfem retinal Display (resolution: 2.880 x 1800 pixels).

A display size, they share Macbooks: 13,3". This size provides a good compromise between mobility and Desktop replacement.
To date (spring 2013), there's the extremely high resolution of the Retina Display only in Macbook - who value on super-sharp-in media player or Apple device to image and video processing needs, the Retina Macbook is not over. However, rumor has it that Apple is the Retina Display in future also in the Air-models build.

Dimensions and weight
Light and flat: Macbook Air, light and flat: Macbook Air During the Macbook Pro performance is designed to convince the Macbook Air is quite clear in terms of mobility. This is reflected in dimensions and weight again: 13,3"variant is the Macbook Air to 300 grams lighter and 1.6 mm thinner than a Macbook Pro with the same screen size.

Due to its compact form, the Macbook Air SSD (flash memory technology). Compared to the conventional (mechanical) hard drives offers the benefits of this technology: it has lower power consumption, is little more vulnerable in case of Fall, and provides faster Write and read rates. Compromise, however, you must storage capacity: The Macbook Air has a maximum of 512 GB, while the Macbook Pro with 750 GB can purchase. The lower capacity makes the Macbook Air, however, the faster and newer flash memory technology up for that.

The Processor
In two Macbooks are dual-core processors are installed. These are, however, when your Macbook Pro is higher clocked and thus offer more performance. The Macbook Pro 15,4" is a Quad-core CPU. The dual-core processors in the Macbook Air are adequate for many applications, for intensive applications such as photo editing, or Video Rendering are the processors in the Macbook Pro, but better suited.

The Graphics Performance
The Macbook Air, you need to have a powerful graphics do without. The graphics performance is sufficient for common applications, large Leistungswunder but are not to be expected. The graphics card on the Macbook Pro is more powerful and provides better conditions for graphics-intensive applications such as Video Rendering or CAD.

No internal drive on the Macbook Air
The Macbook Air, you must click on an internal (DVD)drive altogether. However, you have the option, an external drive connected.

Macbook Air or Per - conclusion
For which Macbook you decide, ultimately depend on their area of application. If you travel a lot, emphasis on mobility and performance rather plays a minor role, are you using the Macbook Air is very good advice. For leistungsintensivere applications such as Rendering, photo editing or CAD, you are on the Macbook better off. A good compromise between mobility and performance, the new Macbook Pro 13,3".

Macbook Air or Pro - the difference between the two Apple notebook is not only the name. Read in this comparison, what are the similaritie...

PC or console? Often the decision, especially when Gaming, especially on the control. Who is the Controller of the PS3 is used, this can, however, also on the PC. With the proper drivers is the Controller set up quickly, so that you also on your PC Games with the Controller can control.

Classic console games, there are often also for the PC. Sometimes it is simple ports. However, regardless miss a console player on the PC, especially a: the professional Controller to a video game. This is a Problem, which, at least in the case of the PS3 controller must not be, because with the right drivers can the PS3 Controller via USB cable easy to connect to the PC and also in the Games on the PC - provided they support a control via a Controller.

What do I need to use the PS3 controller on the PC?

In the first line you need of course a PS3 Controller with the USB cable, because without this, nothing goes. In addition, you still need to have the appropriate drivers MotioninJoy. Make sure the correct driver for your System, download it. Depending on whether you have a 32 - Bit or 64-Bit operating system, you need different Treibervarianten.

What do I do with the drivers?

As soon as the driver file (this is a ZIP or RAR archive) have downloaded, extract it with WinRAR or an alternative Freeware and you can then launch the Setup file. Normally, install the Software in the path C:\Programme\MotioninJoy\ds3 - leave it in this directory.

Once the Installation is completed, connect your PS3 Controller via USB to your computer. Wait a moment until Windows is the Controller has detected. Regardless of which Controller is connected, Windows will try always a private driver. If you wait for a moment, this is also the case for you. The Windows driver is installed, the Controller is connected, however, with the wrong driver it will not work. That is completely normal, so please read more in our guide.

How do I activate the Controller with the right drivers?

Now click on the Start Button and select programs "MotioninJoy" and then "Install USB Driver Right". Click with the right mouse button on the latter Option and run the application as Administrator.

It takes a moment, to the application starts and the correct drivers installed. At the end of Installation, you should have a "SUCCESS" message. If it does not appear, the Installation of the driver failed.

ess the PS Button on your Controller from the sleep to Wake up. You go after it with a click on "Start" to the "devices and printers". As soon as the window is open, choose "Game Controllers".

Again, a window opens. This shows you the reactions, and as soon as a Button press. The biggest hurdles during the Installation, you now have already done.

How can I use the Controller to use now?

To conclude, you will only need the appropriate profile. To do this, click again on "Start" and select the programs in the directory "MotioninJoy" the point DS3 TOOL.

Here you can now from four available profiles, select and vibration settings. The Profiles that are provided are as follows:

Digital Gamepad
In the operation of this profile is similar to the PS1 Controller and is therefore especially suitable for football games.

Analog Gamepad1
This profile is most likely with the PS2 Controller comparable and is one of the most influential profiles available.

Analog Gamepad2
In this Profilvariante are similar to the settings of an XBOX 360 controller, especially when racing games is an advantage.

Analog Gamepad3
This is a barely used profile, similar to the Analog Gamepad2 and was to advanced motion sensor technology.

Other available settings include in conclusion, "Enable Vibrations" in which the vibration Feedback to the controller enable or disable.

Once you have your settings have chosen to confirm this. In connection to your gaming experience on the PS3 Controller is nothing in the way.

The Controller does not work?

You have the driver installed correctly, but the Controller refuses however, its function? At this point, it will be problematic, since there are a number of possible points of failure.

First thing you should do the simplest of problems exclude: do you Have the PS3 Controller is disconnected from the PC and to a different USB Port is infected? If this is the case, you need to add the driver to re-establish. As soon as Windows the new Controller detects the MotioninJoy driver immediately overwritten, which is also the no longer existing function of the controller explained.

Annoying is that when you restart the PC, the driver is to be installed. Do you have your PC so after a long Gaming Session is restarted, you need the driver also play again. However, since this relatively quickly, it is not a long stay.

The last major hurdle is, under certain circumstances, Windows itself. Here, it can happen that the Installation of an alternative driver is denied, since this is not signed. In the startup (booting press F8) you can use the signature to disable.

Take, above all, no one's own "Hardware" measures. What is meant is about the Opening of the hard disk with a screwdriver or the like. Not only will they be unable to resolve the Problem, rather, is that there is the risk that the hard drive has further damaged. A data recovery it is thus unlikely.

To whom can I contact?

Once a hard drive gave up the Ghost, the data only once unattainable. There are numerous companies that are in the read-out and Rescue of specialized data. Some of them even with damaged hard disks work and their data directly back up.

If the hard disk still works but you just accidentally deleted files, you can in many cases even restore. How this works can be found in our article "restore files" on a concrete example.

What is done here?

In the data rescue by experts will make your hard drive in a laboratory once studied and analyzed. This is usually already in the initial error is detected, as well as a rough Overview of the possible to saving the data. Following is a specific procedure to save the data planned. This can be, depending on the Situation be different. Sometimes the mechanical intervention in the hard disk required, which is only by true experts can be done.

As soon as the escape route is planned, this will be directly implemented. Due to the special laboratory equipment may the memory of the hard disk is queried and the lost or damaged files are saved. What is important here is to know that the success rates usually very high, but not 100 percent. Do you expect so, not all of the data to get.
