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

Is an Intel Pentium Dual-Core processor equal to an Intel Pentium M?
No. The Pentium M is an older, 32-bit only processor. The Pentium Dual-Core is faster and supports 64-bit operation.
The Intel 64-bit architecture is a radical departure from the Intel 32-bit Pentium architecture?
Itanium
Is the Pentium 4 a 32 bit or 64 bit processor?
32bit
What is the Intel Pentium III?
The Intel Pentium III was a line of 32-bit processors first released by Intel in 1999. They introduced the SSE instruction set for better multimedia performance, and the controversial unique processor serial number (which was removed in the last revision).
Dual core technology uses 64 bit processor or 32 bit processor?
Both. The Intel Core Duo was a 32-bit dual-core processor. The Intel Core 2 Duo is a 64-bit processor.
The first 32-bit processor from Intel was?
Intel 386 processor, released in October 1985
What is the difference between the Intel 80286 and the Intel 80386?
Comparison between micro processor Intel and Motorola
What is the word size of the Intel 80386?
The Intel 80386 is a 32-bit processor.
What is the typical bus width of an Intel Pentium 4?
32 bit is the default.
What is the theoretical maximum addressable memory by the Intel Pentium III processor?
64 GB when using PAE mode; 4 GB in pure 32-bit mode.
Why Intel microprocessor has 8 bit memory width bt we have 16 bit or 32 or 64 data bus lines?
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.
What is the highest version of Windows you can get for an Intel Pentium III?
Windows 7 32-bit is the highest version compatible with the Pentium III processor. : the official requirement about processor is "a x86 CPU clocked at 1 Ghz or above" and some models of Pentium III meet that technical specification. Please note that only the 32-bit version of Windows 7 can run on Pentium III. Moreover, it is recommended to have at least 1 GB of RAM for Windows 7 32-bit, which is a huge amount for a computer of this era.
