Q. What is Differences and Advantages Between 32-bit (x86) VS 64-bit (x64) Windows Vista?
A. Each editions of Windows Vista operating system is available in both 32-bit and 64-bit versions (x86 anx x64 are terms used by Microsoft), making 64-bit OS option now a widely available choice. And with almost all CPU processor and motherboard nowadays is x64 based which capable of running 64-bit OS, it presents hard decision to consumers to decide and pick whether 32-bit or 64-bit versions of Windows Vista is suitable choice.
Microsoft publishes KB946765 which details the main differences between 32-bit and 64-bit Windows Vista, which mainly relate to memory accessibility, memory management, and enhanced security features, as listed in table below.
| Architecture |
Windows Vista, 32-bit versions |
Windows Vista, 64-bit versions |
| System requirements |
1-gigahertz (GHz) 32-bit (x86) processor or 64-bit (x64) processor,
512 MB of RAM |
1-GHz 64-bit (x64) processor, 1 GB of RAM (4 GB recommended) |
| Memory access |
A 32-bit version of Windows Vista can access up to 4 GB of RAM. |
A 64-bit version of Windows Vista can access from 1 GB of RAM to more than 128 GB of RAM. |
| Memory access per edition |
All 32-bit versions of Windows Vista can access up to 4 GB of RAM. |
Windows Vista Home Basic - 4 GB of RAM
Windows Vista Home Premium - 16 GB of RAM
Windows Vista Business - 128 GB of RAM or more
Windows Vista Enterprise - 128 GB of RAM or more
Windows Vista Ultimate - 128 GB of RAM or more |
| DEP |
32-bit versions of Windows Vista use a software-based version of DEP. |
64-bit versions of Windows Vista support hardware-backed DEP. |
| Kernel Patch Protection (PatchGuard) |
This feature is not available in 32-bit versions of Windows Vista. |
This feature is available in 64-bit versions of Windows Vista. Kernel Patch Protection helps prevent a malicious program from updating the Windows Vista kernel. This feature works by helping to prevent a kernel-mode driver from extending or replacing other kernel services. Also, this feature helps prevent third-party programs from updating (patching) any part of the kernel. |
| Driver signing |
Unsigned drivers may be used with 32-bit versions of Windows Vista. |
64-bit versions of Windows Vista require that all device drivers be digitally signed by the developer. |
| 32-bit driver support |
32-bit versions of Windows Vista support 32-bit drivers that are designed for Windows Vista. |
64-bit versions of Windows Vista do not support 32-bit device drivers. |
| 16-bit program support |
32-bit versions of Windows Vista support 16-bit programs, in part. |
64-bit versions of Windows Vista do not support 16-bit programs. |
If you value the benefits and advantages of switching and embracing 64-bit Windows Vista, here’s a few considerations to ponder before making the move to install x64 Windows Vista:
- 64-bit device drivers may not be available for one or more devices in the computer.
- Device drivers must be digitally signed.
- 32-bit device drivers are not supported.
- 32-bit programs may not be fully compatible with a 64-bit operating system.
- It may be difficult to locate programs that are written specifically for a 64-bit operating system.
- Not all hardware devices may be compatible with a 64-bit version of Windows Vista.
------------------------------------------------------------------------------------
32-bit vs. 64-bit computing?
64 bit computers process data in larger chunks than 32 bit computers. This means a number of things, but the big 2 are:
1) When programs are written to support 64-bit processors, those programs will generally perform faster than on a 32-bit processor of the same speed. This is partially because 32-bit computers must handle 64-bit numbers in two steps, whereas 64-bit computers only need to use one step.
2) 64-bit processors can address more memory than 32-bit processors. This means your server can have more RAM, and therefore can store more data in memory, making memory-intensive programs like databases faster.
As for databases, yes, there are versions of several major databases out there that support 64-bit processors. The one that I am most familiar with is SQL Server of course. SQL Server 2000 is available in a 64-bit version, and is intended to run on the 64-bit version of Windows 2003 Server. Unfortunately, without the underlying 64-bit server OS, I dont believe the 64-bit version of SQL Server will give you any benefit (if it even runs).
Q. What is Active X Control?
A. A control using ActiveX technologies. An ActiveX control can be automatically downloaded and executed by a Web browser. ActiveX is not a programming language, but rather a set of rules for how applications should share information. Programmers can develop ActiveX controls in a variety of languages, including C, C++, Visual Basic, and Java.
An ActiveX control is similar to a Java applet. Unlike Java applets, however, ActiveX controls have full access to the Windows operating system. This gives them much more power than Java applets, but with this power comes a certain risk that the applet may damage software or data on your machine. To control this risk, Microsoft developed a registration system so that browsers can identify and authenticate an ActiveX control before downloading it. Another difference between Java applets and ActiveX controls is that Java applets can be written to run on all platforms, whereas ActiveX controls are currently limited to Windows environments.

Most 64-bit computers can manage exponentially more data than 32-bit systems can. With Windows XP Professional x64 Edition you can design, develop, and interact with new applications, games, and tools that weren’t possible with older technologies. Windows XP Professional x64 Edition provides solutions for current and future use. It delivers more memory combined with the ease of use of the established Windows platform.
Greater flexibility
Windows XP Professional x64 Edition gives you a robust platform for the integration of 64-bit and 32-bit applications using the Windows on Windows 64 (WOW64) x86 emulation layer. You can move to 64-bit computing while still maintaining your existing investment in 32-bit software and Windows expertise.
Multiprocessing and multicore processor support
Windows XP Professional x64 Edition is designed to support up to two single or multicore x64 processors for maximum performance and scalability.
Advantages for specialized, technical applications
The performance of 64-bit computing offers advantages in fields such as automobile and airplane design by allowing engineers to create larger, more complex models. Engineers can use simulation software to analyze the effects of airflow, stress, and heat on the materials of a car or airplane, and then study the results to improve overall product design. Likewise, 64-bit computing benefits digital content creators, including three-dimensional (3-D) animators, digital artists, and game developers, who can significantly reduce the time they spend digitally rendering 3-D models. In the areas of scientific and high-performance computing, Windows XP Professional x64 Edition can aid in oil and gas exploration, seismic analysis, computational fluid dynamics, and scientific visualization, among other applications.
Single desktop for technical and business applications
Windows XP Professional x64 Edition provides a single PC for technical and business applications, so you don’t need to maintain one PC for business applications and a separate workstation for high-end technical applications. Most Windows-compatible 32-bit applications run "as is" in a subsystem of Windows XP Professional x64 Edition, with performance comparable to 32-bit Windows. You can take advantage of rich integration capabilities and productivity tools on the Windows platform. Designers can build a model and easily share it with others in your company, copying it into a Microsoft Office Word document for the finance group or adding it to a Microsoft Office PowerPoint slide deck for the marketing team.
Note: If you use only 32-bit applications and work with data sets that are no larger than 2 GB, you will find that 32-bit Windows XP Professional offers sufficient power for your applications.
Familiar programming model
Developers with 32-bit computing skills will be comfortable and productive in the 64-bit Windows environment, finding the development environments virtually identical. The 64-bit Windows development environment supports the same feature set as 32-bit Windows, including user interface and programming models, networking, security, graphics, multimedia, directory service, Plug and Play, and tools features. Many of the functions have been modified to reflect the computational precision of the platform on which an application is run. The result is programming simplicity and a short learning curve for the developer—writing code for 64-bit Windows is just like writing code for 32-bit Windows.

Q. What is WiFi?
A wireless network uses radio waves, just like cell phones, televisions and radios do. In fact, communication across a wireless network is a lot like two-way radio communication. Here's what happens:
- A computer's wireless adapter translates data into a radio signal and transmits it using an antenna.
- A wireless router receives the signal and decodes it. It sends the information to the Internet using a physical, wired Ethernet connection.
The process also works in reverse, with the router receiving information from the Internet, translating it into a radio signal and sending it to the computer's wireless adapter.
The radios used for WiFi communication are very similar to the radios used for walkie-talkies, cell phones and other devices. They can transmit and receive radio waves, and they can convert 1s and 0s into radio waves and convert the radio waves back into 1s and 0s. But WiFi radios have a few notable differences from other radios:

RAID 6 is designed for tolerating two simultaneous HDD failures by storing two sets of distributed parities. Apparently the complex mechanism is likely to compromise data rate in and out of the system. With direct support from Intel IOP, Enhance has enabled RAlD 6 in both DAS series and iSCSI series with minimal performance hit. RAlD 6 significantly enhances the reliability of the new EnhanceRAID family even both are built upon low-cost high capacity SATA drives.

RAID 5
|

In complex arrays (12-24 drives), RAID 6 applications would be a preferred choice due to the fact that Serial ATA drives used in the arrays have a lower duty cycle and may be more likely to fail in 24/7 or business-critical applications.
|
In small arrays (4-12 drives), RAID 5 applications can quickly repair a failed drive and restore lost data-without taking down the array. It's perhaps the most cost-effective, fault-tolerant data protection solution currently available for small storage devices.
