32-bit application

<architecture, operating system> IBM PC software that runs in a 32-bit flat address space. The term 32-bit application came about because MS-DOS and Microsoft Windows were originally written for the {Intel 8088} and 80286 microprocessors. These are 16 bit microprocessors with a segmented address space. Programs with more than 64 kilobytes of code and/or data therefore had to switch between segments quite frequently. As this operation is quite time consuming in comparison to other machine operations, the application's performance may suffer. Furthermore, programming with segments is more involved than programming in a flat address space, giving rise to some complications in programming languages like "memory models" in C and C++. The shift from 16-bit software to 32-bit software on IBM PC clones became possible with the introduction of the {Intel 80386} microprocessor. This microprocessor and its successors support a segmented address space with 16-bit and 32 bit segments (more precisely: segments with 16- or 32-bit address offset) or a linear 32-bit address space. For compatibility reasons, however, much of the software is nevertheless written in 16-bit models. Operating systems like Microsoft Windows or OS/2 provide the possibility to run 16-bit (segmented) programs as well as 32-bit programs. The former possibility exists for {backward compatibility} and the latter is usually meant to be used for new software development. See also Win32s. (1995-12-11)

32-bit disk access

32-bit Disk Access

32-bit Disk Access (also known as FastDisk) refers to a special disk access and caching mode available in older, MS-DOS-based Microsoft Windows operating systems. It was a set of protected mode device drivers that worked together to take advantage of advanced disk I/O features in the system BIOS.

32-bit file access

32-bit File Access

32-bit file access refers to the higher performance, protected mode disk caching method introduced in Windows for Workgroups 3.11, which replaced SmartDrive (Smartdrv).

32-bit computing

In computer architecture, 32-bit computing refers to computer systems with a processor, memory, and other major system components that operate on data in 32-bit units. Compared to smaller bit widths, 32-bit computers can perform large calculations more efficiently and process more data per clock cycle. Typical 32-bit personal computers also have a 32-bit address bus, permitting up to 4 GB of RAM to be accessed; far more than previous generations of system architecture allowed.

32-bit designs have been used since the earliest days of electronic computing, in experimental systems and then in large mainframe and minicomputer systems. The first hybrid 16/32-bit microprocessor, the Motorola 68000, was introduced in the late 1970s and used in systems such as the original Apple Macintosh. Fully 32-bit microprocessors such as the HP FOCUS, Motorola 68020 and Intel 80386 were launched in the early to mid 1980s and became dominant by the early 1990s. This generation of personal computers coincided with and enabled the first mass-adoption of the World Wide Web. While 32-bit architectures are still widely-used in specific applications, their dominance of the PC market ended in the early 2000s.

1. All the versions for consumers and businesses are available for both 32–bit or 64–bit computer systems.

2. Sixty–four–bit processors can crunch twice as many bits of information at one time as the more prevalent 32–bit processors.

3. Its development of chips capable of processing 64–bit at a time, or twice as much data as conventional 32–bit chips used in most PCs, has helped AMD to snatch back market share from Intel Corp, the market leader in PC microprocessors.

4. "Building on our positive momentum, we believe we once again gained dollar market share based on strong customer demand for AMD64 single and multi–core processors." The move to computing that addresses 64–bit instead of 32–bit memory and from single–core to dual–core processors has been driving sales for Intel and AMD, which share the market for the dominant "x86" family of microprocessors.

5. We tested the latter, which includes a processor near the top of Intel‘s Core 2 Duo line and movie–oriented ATI Mobility Radeon HD3650 graphics. (The midrange graphics card has some lesser specs than many gaming enthusiast cards, but it does incorporate AMD‘s Unified Video Decoder, which is designed to lighten the processing load on the CPU when displaying HD video.) Because the M70 ships with the 32–bit version of Windows Vista, it‘s only capable of accessing 3GB of its generous 4GB RAM allotment; it would have made more sense to ship with the 64–bit version of Windows so that last 1GB of RAM wasn‘t sitting dormant.
