 32-bit - Wikipedia, the free encyclopedia
In computer architecture, 32-bit is an adjective used to describe integers, memory addresses or other data units that are at most 32 bits (4 octets) wide, or to describe CPU and ALU architectures based on registers, address buses, or data buses of that size.
The range of integer values that can be stored in 32 bits is 0 through 4294967295, or -2147483648 through 2147483647 using two's complement encoding.
The external address and data buses are often wider than 32 bits but both of these are stored and manipulated internally in the processor as 32-bit quantities.

 Interoperability of 32- and 64-bit applications on 64-bit HP-UX - HP Dev Resource Central
For 32-bit applications running on 64-bit HP-UX to communicate correctly with the operating system and with 64-bit applications, it is necessary to create an environment where both types of applications can exchange information with no loss of data or accuracy, and share resources in a way that optimizes the performance of each application.
When a 64-bit application shares a memory segment with a 32-bit application, and if the 64-bit application created the shared memory segment, the application must tell the system to use 32-bit addressing to map that shared memory segment.
Therefore, if a 64-bit application is used to create a memory-mapped file with the intention of sharing it with 32-bit applications, it must inform the system so that the system uses 32-bit virtual addressing.

 Use of dl_setuio() in 32 Bit OS/2 Applications
When you write a 32 bit application and re-define the read, write, and seek functions, you are providing a 16 bit driver and dll with a pointer to 32 bit code to execute.
Even though you can "thunk" the application pointers to the functions so that the driver can address them, the driver cannot execute the 32 bit code being pointed to because it is a 16 bit driver.
This is why when dl_stuio() is used with a 32 bit application, the driver will cause operating system errors when records and plays of files are performed.

 How To Use a 32-Bit Application to Determine When a Shelled Process Ends
In a 32-bit application, you need to create an addressable process.
A 16-bit application would use a completely different technique to accomplish the same effect.
However, if your Visual Basic application needs to wait for the shelled process to terminate, you could use the Windows API to poll the status of the application, but this is not a very efficient technique.

 32-Bit Computing - What's It All About?
If you have two computers whose clock (processing) speed is identical, and one processes 32 bits at a time while the other processes 16, the 32-bit computer will be about twice as fast.
All other things being equal, the more bits your computer can process at the same time, the faster it is. Most desktop computers manipulate bits in groups of 16 or 32.
With cooperative multitasking, the operating system gives control to an application and it is the application's responsibility to release control.

However, it is possible for 64-bit applications to launch 32-bit processes, and vice-versa, and to share handles to named objects (such as semaphores and file handles) and to individual windows.
This allows a 32-bit application to see a system image and resources that make it believe that it's running on a standard 32-bit version of Windows; obviously a 32-bit app wouldn't understand the hardware changes in a 64-bit system.
If you're writing a 64-bit application that needs to be aware of what's going on with the 32-bit infrastructure, Microsoft has provided some special functions that can assist you.

 Intel to boost 32-bit application handling by Itanium 2 - Computerworld
In addition to running 64-bit applications, users of the new Opteron CPUs will be able to run older 32-bit applications at speeds comparable to their performance on older x86 32-bit hardware or faster, according to the company.
The software code is expected to allow 32-bit applications running on Itanium 2 to have performance on par with an Intel 32-bit Xeon 1.5-GHz MP processor, he said.
Instead, the chips are engineered to work best with the new generation of 64-bit applications that are beginning to make their way onto the market.

 Notes on 64-bit Drivers and STREAMS: A White Paper
To enable a 64-bit driver and a 32-bit application to share memory, the binary layout generated by the 64-bit driver must be the same as consumed by the 32-bit application.
Otherwise, the driver needs to be aware of the different structure shapes for ILP32 and LP64 and determine whether there is a model mismatch between the application and the kernel.
However, some pseudo-devices that export mappings to the user address space might want to export different data structures to ILP32 or LP64 applications.

This would permit the developer to build one application and distribute it as a demonstrative (demo) copy and, at the same time, as a full version copy that only needs to be branded to be converted from its demo state.
Constant values can be branded to an application to change the outcome of computations or to customize generated reports; encryption keys can be "burned" into executables for heightened security; email addresses and web site addresses can be secretly embedded into internet applications to intercept information from the end-user's computer.
