32bit
No. The Pentium M is an older, 32-bit only processor. The Pentium Dual-Core is faster and supports 64-bit operation.
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.
Q6600 is a 64 bit processor, but it can execute in 16 and 32 bit modes.
Depends on the model, all Pentium 4's running on Northwood are 32 bit, however some of the higher end Prescott and newer chips are 64 bit (Pentium 4 5xx and 6xx series). To find out if your pentium 4 is 64bit search for CPUz on google and that will tell you everything you need to know about your CPU
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.
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.
Yes, as long as you have a 64-bit capable processor. A Core 2 Duo, Pentium 4 (Cedar Mill Core), or a Pentium Dual-Core would be capable. An Intel Core Duo is 32-bit only.
Both. The Intel Core Duo was a 32-bit dual-core processor. The Intel Core 2 Duo is a 64-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.
64 GB when using PAE mode; 4 GB in pure 32-bit mode.
No.
Intel has released processor with a variety of bus / memory widths. The 386SX had a 16-bit data width, the 386DX and 486 had a 32-bit bus width, and the Pentium had a 64-bit data bus.
