Today 32-bit computers are currently being used commonly and the 32-Bit microprocessors are still in production widely across the globe. The common Windows XP Editions uses the 32-bit architecture, as well as Windows Vista/7 32-bit types. However the PCs and Servers running on 32-bit can only use up to 4 GB RAM maximum; most 32-bit PCs are x86 based which are descended from the Intel i386 family? The Intel processors are currently in direct competition with the AMD processors.

There are other 32-bit processors like the PowerPC that were used for the early Apple iMac machines until they switched to Intel in 2006. Most 32-bit processors are useful for laptops that consume less battery power and clock cycles, that provide a long battery life span. Other 32-bit machines can be found in game consoles and smartphones. The Windows 95 was Microsoft's market success to where it introduced the 32-bit architecture and applications, that had revolutionised the computing and office industry. Unlike the old Windows 3.1x, which is Windows 95 precedessor, the Windows 3.1x does not operate in 32-bit. Many 32-bit machines were introduced as home computers and game consoles near the mid-1990s' that made the old 16-bit machines obsolete and outdated.
