DOES EVERYTHING IN UNIVERSE WE SEE IS REAL??

-->Is it true that the stars or other we see may not exist practically now but we still see them     on the sky?

-->Does stars ,moon etc we see in the universe are at not real with respect to time?

-->Is it true that the stars we see may be already dead?

Answer is yes..

Reality as  we sense it, is not quite real. The stars we see in the night sky, for instance, are not really there. They may have moved or even died by the time we get to see them. This unreality is due to the time it takes for light from the distant stars and galaxies to reach us. We know of this delay.It is explained below 

 For example a star  approximately 500 light years(light year is the distance travelled by the light in one year)  away from earth, so when we look at that star,light from the corresponding star travels 500 years and reaches to earth and then on our eye,so what we're actually seeing is what that star looked like 500 years ago!.That means we are seeing the light of star which is emitted 500 years ago!!.so the star may or may not exist or present at that point but its image of 500 years back.

 

Even the sun that we know so well is already eight minutes old by the time we see it.

So everything in universe we see is not in real time and its delayed with some time as light takes some time to travel.(Basic point is we can see an object only if light is projected on that object or emmitted from that object).

DIFFERENCE BETWEEN X64 AND X86

x86 refers to any processor that is instruction-compatible with the Intel 8086 and higher. This includes the Pentium, Pentium II, Celeron, Pentium III, Pentium 4, Pentium D, Core Duo, Core 2 Duo, Core i7, Atom, AMD Athlon, Sempron, Athlon 64, Phenom, and Geode. In summary 32 bit type processors

x64 is often used to refer to any x86 processor that has 64-bit extensions (x86-64). These include the AMD Athlon 64, late models of the Pentium 4, Pentium D, Core 2 Duo, Phenom, and certain Geode processors. In summary 64 bit type processors


x32 is a retcon of the x64 term to apply to either 32-bit only processors or programs.

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 – 8 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.

HOW TO CHOOSE A GRAPHIC OR VIDEO CARD?

WHAT IS A VIDEO CARD?
A video card or graphic card is a device that allows for the visualization of images on your computer monitor. Without the card you would not be able to view images, play games or see colors. If you are anything less than a graphics card expect, the shopping process for a video card can be grueling. With a bit of knowledge it should make the trip easier and you may just come home with the correct video card. There are currently more than sixty types of video cards that range in price and specifications. In order to decide which card is right for you there are a few things that you must understand first. Keep in mind the type of computer, purpose and uses of the computer, as well as the expectations for rendered image. After that is all decided you must remember your budget when shopping for the video card.
The type of computer that you have is one of the most important issues when deciding on a video card. You must ensure the compatibility of the card with your PC or it could be a waste of money. To ensure compatibility you will need to know what type of card slot the computers mother board has for the video card. There are three types of card slots that we will discuss further.

PCI Slot : the PCI slot is short for Peripheral Component Interconnect and is not exclusive with any one processor type. PCI was the first expansion slot made by computer manufacturers. The PCI has limited performance, but there are several value cards that offer acceptable performance.

AGP Slot :the AGP slot is short for Accelerated Graphics Port. AGP has many versions and was first designed for 3D gaming abilities. Today the AGP 2.0 and 3.0 are sold, but the 1.0 is no longer in use.

PCI Express:this is the latest card slot and is up to four times faster than the PCI slot or AGP slot. 
The PCI Express was made with the intention of replacing the PCI and AGP slots for the extended performance ability. Note PCI and PCI Express are not compatible and are very different products, not to be confused with one another.
Along with knowing the card slot type you must also know the requirements and specifications of the CPU. When we refer to requirements and specifications we mean the CPU type and speed. If you are purchasing a video card for regular viewing the 500 MHz will suffice, but for optimal use the 800 MHz is suggested. When viewing images it is important to have a higher MHz or your system may become overloaded. The 1600 MHz range is suggested for limited 3D gaming and running other applications such as business applications or graphics. For optimal 3D gaming the minimum CPU would be 2.4 GHz. Much of the CPU speed depends on computer use and personal budget. The faster the CPU the better and more realistic the special effects are. Cost rises as CPU speed rises!

Speed up Windows 7 Performance

Basic Nine Tips to Speed up Windows 7 Performance

The new Microsoft operating system - Windows 7 is awarded with the word "impressive" by the masses, but it still gets complaints from early adopters on the web. Having spent couples of days in forums and communities full of discussion about Windows 7, I find that Windows 7 can easily slow down due to various issues just as its predecessors, Windows XP or Vista.

Well, there is no rose without a thorn. For enjoying the non-compromised features of Windows 7 and keeping its freshness as long as possible, you can take the following top 9 tips to speed up Windows 7 performance, and save your time, money as well as get full control of your PC!

Tip 1 to speed up Windows 7 performance: Cleanup Hard Disk Windows temporary files, internet cache, cookies, invalid shortcuts and unused files and programs can take up much room on your hard disks. Even you have just upgraded to Windows 7, those junk files can soon accumulate and eat up hard disk space. So regular disk cleanup should be part of your daily work to keep Windows 7 running fast.

Windows 7, as its predecessors, has a built-in Disk Cleanup program, you can find it in Start>Accessaries>System Tools>Disk Cleanup. But this built-in tool takes quite a long time to scan your hard disk and is able to clean very limited junk files. So a third-party disk cleaner is recommended to use to save your time and perform a more complete disk cleaning job.
