Various Types of RAID
RAID stands for Redundant Array of Independent Disks and is widely used in commerical sectors. Using a RAID storage subsystem has the following advantages:
- Provides disk spanning by weaving all connected drives into one single volume;
- Increases disk access speed by breaking data into several blocks when reading / writing to several drives in parallel operations. With RAID, storage speed increases as more drives are added;
- Provides fault-tolerance by mirroring or parity configuration.
Common terms that you will need to understand more include:
NRAID stands for Non-RAID. The controller treats each drive as a stand-alone disk, therefore each drive is an independent logical drive. NRAID does not provide data redundancy.
JBOD stands for Just a Bunch of Drives. The capacity of all the drives is combined to become one logical drive (no block striping). In other words, the capacity of the logical drive is the total capacity of the physical drives. JBOD does not provide data redundancy.
RAID 0 provides the highest performance but no redundancy. Data in the logical drive is striped and distributed across several physical drives on the same volume.
RAID 1 mirrors the data stored in one hard drive to another. RAID 1 can only be performed with two hard drives. If there are more than two hard drives, RAID (0+1) will be performed automatically.
RAID (0+1) Disk Striping with Mirroring. This configuration combines RAID 0 and RAID 1 - Mirroring and Striping. RAID (0+1) allows multiple drive failure because of the full redundancy of the hard drives. If there are more than two hard drives assigned to perform RAID 1, RAID (0+1) will be performed automatically.
RAID 3 Disk Striping with Dedicated Parity Disk. One drive member is dedicated to storing the parity data. When a drive member fails, the controller can recover / regenerate the lost data of the failed drive from the dedicated parity drive.
RAID 5 Striping with Interspersed Parity. RAID 5 is similar to RAID 3 but the parity data is not stored in one dedicated hard drive. Parity information is interspersed across the drive array. In the event of a failure, the controller can recover/regenerate the lost data of the failed drive from the other surviving drive.
Fully understanding the physical storage configurations is a must for better manage and control your data storage strategic and emergency planning.

Lawrence Krauss is an internationally known theoretical physicist and bestselling author, as well as being an acclaimed lecturer. He has also appeared regularly on radio and television, as well as in several feature films. His wide research interests have focused on the interface between elementary particle physics and cosmology, including the origin and evolution of the Universe and the fundamental structure of matter. Among his numerous important scientific contributions was the proposal, in 1995, that most of the energy of the Universe resided in empty space. The astronomers whose observations later demonstrated this were aware the Nobel Prize in Physics in 2011.

If you want to be aware of how to make some type of computer virus, you need to understand that https://kvbhel.org/ there are several many types. There are simple ways to choose a own contamination, and you need not know any kind of codes or perhaps special skills. In fact , you can create a contamination in only minutes. Keep reading to discover a few of the easiest ways to create a computer virus. You can even down load the instructions and download the computer onto your pc!
Many computer system viruses enter in a computer through email accessories or various other files. They will also be downloaded from the Internet and attached to free/trial software. Most viruses happen to be attached to executable data files, and they propagate only if you interact with them. For example , a virus may infect a whole computer system in case the user clears an email connection. Another way to unfold a strain is to download a vicious browser file format to the pc.
Those who build computer infections usually target Home windows machines, as they have a substantial installed bottom. However , they will also assail other products, including IoT gadgets. Infections can contaminate any pc that can operate code. There are two types of computer malware: resident and macro. The previous infect currently-executing programs, as the latter infects macro applications embedded in files. The purpose of both types is to trigger destruction.

Difference Between 32 bit & 64 bit Operating Systems
The terms "x64" and "x86" refer to different computer architectures used in modern processors. They indicate whether the processor and the operating system are 64-bit or 32-bit, respectively. Understanding the difference between x64 and x86 is essential when installing software, choosing an operating system, or ensuring compatibility with hardware and applications. Let's explore the details of each architecture:
- x86 architecture, also known as 32-bit architecture, is the older and more traditional architecture used in processors and operating systems. It takes its name from the original Intel 8086 processor, which was a 16-bit processor.
- The x86 architecture supports a maximum of 4 gigabytes (GB) of RAM, which means that 32-bit operating systems and applications can access up to 4 GB of memory.
- In practical terms, due to memory limitations, a 32-bit operating system might not be able to utilize the full 4 GB of RAM, as some memory is reserved for system processes and hardware mappings.
- The memory addresses in x86 architecture are represented using 32 bits, allowing a theoretical maximum of 2^32 (4,294,967,296) memory locations to be addressed.
x64 (or x86-64 or AMD64)
- x64 architecture, also known as 64-bit architecture, is the newer and more advanced architecture used in modern processors and operating systems. It evolved from the x86 architecture to support 64-bit computing.
- The x64 architecture allows for significantly larger memory addressing, enabling access to much more RAM. A 64-bit operating system can theoretically address up to 16 exabytes (EB) of RAM (1 EB = 1,024 PB), which is a massive amount of memory compared to the 4 GB limit of x86 architecture.
- With the ability to access more RAM, 64-bit systems can handle more complex applications, perform better with memory-intensive tasks, and support advanced software, particularly in fields like graphics, video editing, and scientific computing.
- The memory addresses in x64 architecture are represented using 64 bits, providing a much larger address space than the 32-bit x86 architecture.
- Memory Addressing: x86 architecture uses 32-bit memory addressing, limiting the amount of RAM accessible to around 4 GB, while x64 architecture uses 64-bit memory addressing, enabling access to much larger amounts of RAM, up to several exabytes.
- Application Compatibility: 32-bit applications are designed to work on both x86 and x64 systems, but 64-bit applications are specifically optimized for x64 architecture. However, most modern systems are backward compatible and can run 32-bit applications on 64-bit operating systems.
- Performance: In general, 64-bit systems perform better in memory-intensive tasks due to their ability to access larger amounts of RAM and utilize more powerful instructions.
- Compatibility: Some older hardware and software may not be compatible with 64-bit systems, as they were designed for 32-bit environments. However, most modern hardware and software support 64-bit architecture.
Choosing Between x64 and x86
For most users and modern systems, using a 64-bit operating system (x64) is recommended, as it provides better performance, access to more RAM, and compatibility with the latest software. However, if you have older hardware or specific software requirements, you may need to use a 32-bit operating system (x86). Always check the system requirements of the software and ensure that your hardware supports the chosen architecture.
How to determine if Windows OS is 32-bit (x86) or 64-bit (x64)
Open the Power User menu. Press the Windows key + X to open this menu. Click on System.
There is ne another way you can understand that if your PC is running 64-bit Windows, you'll probably find a Program Files (x86) folder on your hard drive. This stores 32-bit applications, while the other 'Program Files' folder contains all the 64-bit apps you've installed.

First and most important thing to consider when buying your motherboard – what CPU or processor are you using? Motherboards are made differently, not all motherboards will support all CPUs. What CPU you select will determine the type of motherboard you get.
For example, if you want to use an Intel Pentium 4 CPU, the motherboard you select must be able to support that brand and model of CPU. The motherboards are also designed to support specific speeds for a CPU, so make sure it can support the speed of the processor as well nytuesday.
Choose Your Chipset
What is a chipset? Well, chipsets are the main controllers on the motherboard – they allow the CPU to interface with the various components and expansion cards installed.
When choosing your chipset, always bear in mind the type of memory supported by the motherboard. Make sure that the board supports the type and amount of RAM you need. Generally, choosing a chipset that supports high speed memory will allow your system to perform better.
Expansions Slots and Connectors
If you intend to various peripherals to the computer, then the number and type of expansion slots and connectors is important. By default, most motherboards these days have USB 2.0 ports incorporated into their design. If you do a lot of video capturing and editing, you’ll also want to have a Firewire (IEEE 1394) port. If you intend to buy expansion cards, make sure the board comes with an ample number of PCI slots.
Do You Need to Overclock?
If you want to overclock your CPU (though I don’t particularly encourage it) – you should ensure you get a motherboard that supports overclocking. You’ll want a motherboard that has a wide range of adjustments to CPU settings, including CPU voltage and bus speeds.
These days, most motherboards have a whole host of extra features loaded into them. These can include things such as on-board Ethernet, audio, a RAID controller or even graphics. I find such features very handy as they help you save money – you need not buy additional expansion cards.
In short, make sure you do your homework when purchasing a motherboard. Go to the motherboard manufacturer’s website and read about its products. Download the motherboard manual and see if its well documented.


Höchstauflösende NMR-Spektroskopie in Lösung und im Festkörper – 1 GHz AEON NMR Spektrometer (Gerätekategorie I):
The Bruker 1 GHZ AEON NMR spectrometer is one of the most powerful spectrometers in the world. In fact, it is the only instrument on the word that is independent of regular refills with liquid nitrogen and liquid helium for cooling purposes. Therefore, time limitations due to the cryogen refill-cycle are obsolete on this instrument. Due to its high magnetic field strength of 23,4 Telsa and the adjacent proton resonance frequency of 1000 MHz this instrument allows measurements at highest sensitivity and resolution. The instrument was granted to University of Bayreuth in 2011 in a competitive process by the “Wissenschaftsrat” and the „GWK (Gemeinsame Wissenschaftskonferenz) von Bund und Ländern“. Since 2016 it is in operation.
The 1 GHz NMR spectrometer can measure samples either in solid phase or in liquid phase (after change of probes).

Further information regarding research and publications can be found on the web-sites of the individual Chairs.
Regarding access to spectrometers members of the NBNC are requested to contact the person in charge for the relevant instrument as listed in the intranet.
Any other request shall be directed at the management of the NBNC.


The big screen, hand-gesture software depicted in the film ‘Minority Report’ is now becoming a reality. Scientist John Underkoffler has developed the interface to enable users to sift through masses of data. The system is intended to help facilitate workflow between multiple users. Kwin Kramer, chief executive of Oblong who developed the system observes that a business can have masses of data at its disposal, but it can be difficult to make use of this when it is hard to access and on different machines. This software changes that.
The gesture interface is called “g-speak” spatial operating environment and some systems use a glove rather than the hand alone. There have even been requests from the military for this interface. Unlike the onscreen version though, the software does not provide ‘pre-crime’ detection data, however it could be extended by law enforcement agencies, who could add their own analytics for this purpose.

How Solar Works
Powering your home with Sunlight
The Basics of
Home Solar Energy
Most people have basic knowledge of how solar panels work, but not as many people understand how they can benefit from them. Here’s a crash-course on home solar power, and how it can help you save thousands of dollars in energy costs.
Traditional Power and
Most of the power used in homes across the U.S. is delivered through a massive network of generators, wires, and stations. This network is called “the grid”. The grid is usually owned by large corporations, which are sometimes regulated by state and local governments. If you own a house, chances are these corporations send you a bill every month for the power you use.
Home Solar Systems
When a solar system is installed on your home, attractive, low-profile solar panels are attached to your roof. Your home becomes its own small-scale power generation plant, and you eliminate the need to buy most of your power from the power utility. Any extra power your system produces is put back onto the grid and sold to your neighbors, and you get energy credits applied to your account.
Net Energy Metering
A critical component to residential solar systems is the Net Energy Meter. A Net Energy Meter doesn’t look much different than the meter you have now, but it’s capable of running in both directions. You’re able to pull power from the grid, as well as put power back onto the grid. Your utility then credits your account for excess energy produced. These credits are then used by you at a later time. It’s all automatically monitored, so there’s nothing you need to figure out or do.
Pulling It All Together
As power is produced by your solar panels, it travels into a power inverter which converts the electricity into a usable form. Your own power needs are met first, and if excess electricity is available, it goes back onto the grid through your Net Energy Meter. This meter keeps track of how much energy the utility owes you in return. If your system is producing less power than what you need, you still have the connection to the grid to draw power as needed, and rather than paying the going rate for it, you use the credits you’ve built up first. This is particularly useful to avoid peak-time rates during those hot summer months.
Solar + NEM = a Better Way to Power Your Home
Solar panels produce the most power during the time of year when demand and rates are at their highest. People with solar homes enjoy lower energy rates year-round, and only buy power from their utility companies at the lowest rates, if they buy any at all.


One of the features of our new Sony FS700 is high-speed videography; it’s able to shoot video up to 960 frames per second. When these frames are played back at the standard rate of 30 fps, any movements that were recorded take place much more slowly. This technique is so appealing because it is able to reveal a secret nature of movement that is unappreciated by the naked eye.
A slow-motion camera is to time as a microscope is to space; just as a microscope expands distances to reveal the unseen, a slow-motion camera can expand time to reveal what otherwise would not be known. On the other hand, a time-lapse camera is to time as telescopy is to space—just as a telescope compresses distances and brings us closer to the stars, a time-lapse camera compresses time, and provides an otherwise unknowable experience.
A few days ago we decided to hook up with our buddy Kent Willard and do a little time microscopy, testing out this new camera by diving deep into microseconds to look at unseen elements of movement.
