No, it is a 32-bit processor in the sense of using 32-bit virtual addresses and having 32-bit general purpose registers and ALU that operates on those 32-bit GPRs. It does feature "MMX Technology", which can process 64-bits of information at a time by reusing the FPU's registers, however, in the more common usage, it is not considered a 64-bit processor due to the lack of 64-bit virtual address space and 64-bit GPRs.
The i7 is a 64 bit processor.
64bit processors have most registers specially the integer registers as 64bit. It can handle 64bit wide internal and external data. All internal and external buses may or may not be 64bit wide. - Neeraj Sharma
Q6600 is a 64 bit processor, but it can execute in 16 and 32 bit modes.
A 32 bit processor has 32 bit wide data bus while a 64 bit has 64 bit wide data bus. Address bus may or may not be 32 bit or 64 bit wide in the respective processors. To fully utilise the 64 bit data bus the programs must be written in such a way that they can use 64 bit wide data bus. A 64 bit processor can also act as 32 bit.
To use 64-bit specific applications, you must purchase both a 64-bit processor and a 64-bit version of Windows. 64-bit applications will not run on 32-bit versions of Windows, even if a 64-bit capable processor is installed. You also cannot install a 64-bit version of Windows on a 32-bit only processor.
It is a processor that works with 64 bit values instead of 32 bit values. The advantages are that it is much faster for operations on large 64 bit values for which a 32 bit processor would need multiple operations. This means that a 64 bit processor with the same clock speed can do more work in the same time.
Both. The Intel Core Duo was a 32-bit dual-core processor. The Intel Core 2 Duo is a 64-bit processor.
One limitation of a 16 bit processor, compared to a 64 bit processor, is computing speed. A 16 bit process can process 2 bytes (8 bits = 1 byte) of information per clock cycle. While a 64 bit processor can process 8 bytes of information per clock cycle, making the 64 bit processor four times faster than a 16 bit processor.
Installing Linux on a 64-bit processor is no different than installing it on a 32-bit processor. Especially on systems that offer both a 32-bit and 64-bit version, the difference is totally transparent, and the install identical.
You can do this by identifying your processor brand and model. Many tools that can do this, such as CPU-Z, will also list the features of the processor for you, such as EM64T (on Intel processors) or x86-64 (on AMD processors). Note that it is quite possible to run a 32-bit operating system and programs on a 64-bit capable processor, so just because you are running one doesn't mean you can't run a 64-bit one.
8086 is a 16bit processor.
