title: What are the most common CPU architectures and system platforms for personal computers?
body: <p>NodeJ has built-in methods for detecting the machine it is running on:</p>
  <p><code>process.arch</code> returns the operating system CPU architecture. Possible values:</p>
  <ul>
  <li><code>arm</code> - 32-bit  Advanced RISC Machine</li>
  <li><code>arm64</code> - 64-bit  Advanced RISC Machine</li>
  <li><code>ia32</code> - 32-bit Intel Architecture</li>
  <li><code>mips</code> - 32-bit Microprocessor</li>
  <li><code>mipsel</code> - 64-bit Microprocessor</li>
  <li><code>ppc</code> - PowerPC Architecture</li>
  <li><code>ppc64</code> - 64-bit PowerPC Architecture</li>
  <li><code>s390</code> - 31-bit The IBM System/390</li>
  <li><code>s390x</code> - 64-bit The IBM System/390</li>
  <li><code>x32</code> - 32-bit extended systems</li>
  <li><code>x64</code> - 64-bit extended systems

  </ul>
  <p><code>process.platform</code> returns the operating system platform. Possible values:</p>
  <ul>
  <li><code>aix</code> - IBM AIX platform</li>
  <li><code>darwin</code> - Darwin platform(MacOS, IOS etc)</li>
  <li><code>freebsd</code> - FreeBSD Platform</li>
  <li><code>linux</code> - Linux Platform</li>
  <li><code>openbsd</code> - OpenBSD platform</li>
  <li><code>sunos</code> - SunOS platform</li>
  <li><code>win32</code> - Windows platform
  <a href="https://nodejs.org/api/process.html#processplatform" rel="nofollow noreferrer">https://nodejs.org/api/process.html#processplatform</a></li>
  </ul>
  <p>When using both combinations of values there are: <code>11 architectures x 7 platforms = 77 possible combinations</code>. It's not realistic to build/test/support all of them.</p>
  <p>What are the most common CPU architectures and system platforms for personal computers?</p>
  <p>(Would be great if you have computer sales data, market share, website viewer statistics, e.g. <a href="https://gs.statcounter.com/os-market-share" rel="nofollow noreferrer">https://gs.statcounter.com/os-market-share</a>)</p>
