What is a common characteristic of most computers developed in the last two decades in terms of architecture?

Most computers developed in the last two decades have been designed to run on a 64-bit processor architecture. This is a significant evolution from earlier 32-bit and 16-bit systems. The transition to 64-bit architecture allows computers to utilize more RAM, resulting in enhanced performance capabilities, especially in multitasking and processing large data sets.

While some systems might still support or utilize 32-bit architectures for compatibility reasons, the predominant trend over recent years has been the widespread adoption of 64-bit processors. This adoption enables systems to take full advantage of modern software applications and operating systems, which are designed to operate efficiently on 64-bit architecture.

Choosing 16-bit or 32-bit architecture would limit a computer's performance and capabilities, particularly with current software demands. Additionally, the idea that most computers only support mobile platforms is inaccurate, as many desktops and laptops are built with 64-bit architecture to maximize their functionality across diverse computing environments.
