Subsequent upgrades, if any, may not have jumped your install up to 64-bit. More likely, you have an old system with an operating system you installed that only came as 32-bit. If you've bought a PC since the Pentium D chip came out in 2005, it's unlikely you'd have only a 32-bit instruction set inside. Intel started making 32-bit processors in the 80386 range way back in 1985 it was selling 64-bit processors by 2001. Why would you install a 32-bit OS on a PC? The big reason is because you have a 32-bit processor, which requires a 32-bit OS. In fact, as of the latest version (10.14 Catalina) 32-bit applications on a Mac aren't even technically supported, but we have a guide for running 32-Bit apps in MacOS Catalina. Mac users don't have to worry about this, as MacOS has been 64-bit only for a long time. Under the Device specifications heading, you'll see it at System type: "64-bit operating system, 圆4-based processor" means you're covered. In Windows 10, go to Settings > System > About or type About in the Windows 10 search box. If you are running Windows on a computer less than 10 years old, your chip is almost guaranteed to be 64-bit, but you may have installed a 32-bit version of the OS.
How do you even tell which one you have? Identify a 64-Bit OS Windows 7, 8, 8.1, and 10 all came in 32-bit or 64-bit versions, for example. These days, you are most likely already running 64-bit chips with 64-bit operating systems, which in turn run 64-bit apps (for mobile) or programs (on the desktop, to settle on some nomenclature). You might know 32-bit as x86, a term that originally referred to any OS with the instruction set to work on Intel chips like the 8086 through 80486. It's pretty obvious: 64-bit, sometimes styled as 圆4, is capable of doing more than 32-bit. The first smartphone with a 64-bit chip (Apple A7) was the iPhone 5s in 2014.

Apple made Mac OS X Snow Leopard entirely 64-bit in 2009.AMD shipped the first 64-bit desktop chip in 2003.In 1992, Windows 3.1 was the first 16-bit desktop version of Windows.The Intel 8080 chip in the 1970s supported 8-bit computing.That's because every few years, the chips inside the computers (even smartphones) and the software running on those chips make leaps forward in supporting a new number. That's a lot of bits, and the numbers show just how much more powerful a chip that supports higher-bit computing can be. Each one is a considered a "bit." That means for 1-bit computing, you get two possible values 2-bit means four values then at 3 bits you double that to eight (2 to the third power, aka 2 cubed). There are a lot of ways to count, but when it comes to computers there is only binary: 0 and 1.
