This post covers the x86 architecture, a fundamental aspect of modern computing systems. In this article, you will find detailed explanations of x86 terminology, its variations, and its relevance in the computing landscape.
What is x86?
x86 is a family of instruction set architectures (ISAs) developed by Intel and later adopted by other manufacturers. It originated with the Intel 8086 microprocessor in 1978 and has since evolved through various iterations. The x86 architecture is prevalent in personal computers and servers, primarily running Windows and Linux operating systems.
The term “x86” refers to the original 16-bit architecture and its subsequent 32-bit versions (like the 80386 and 80486), but it has since expanded to encompass 64-bit processors as well, often referred to as x86-64 or AMD64. This architecture supports a wide range of applications and software, making it one of the most widely used architectures in personal computing.
What is the Difference Between x64 and x86?
The primary difference between x64 and x86 lies in their architecture and processing capabilities:
- x86: Refers to the 32-bit architecture. It can handle a maximum of 4 GB of RAM and utilizes 32-bit data buses. x86 systems can run 32-bit applications and operating systems.
- x64: Refers to the 64-bit architecture. It can address a significantly larger memory space, theoretically supporting up to 16 exabytes of RAM. x64 systems can run both 64-bit and 32-bit applications. The 64-bit architecture improves performance, particularly for applications requiring extensive memory or processing power.
What Does x86 Mean?
The term “x86” originally referred to the 16-bit Intel 8086 processor and its successors. It has since evolved to describe a family of processors that follow the same instruction set architecture. In a broader sense, “x86” encompasses both 32-bit and 64-bit versions, particularly in contexts where compatibility with older software is essential. The x86 instruction set allows for the execution of a wide range of applications, contributing to its enduring popularity in personal computing.

What is the Difference Between Program Files and Program Files (x86)?
On Windows operating systems, the “Program Files” and “Program Files (x86)” directories serve different purposes related to application architecture:
- Program Files: This directory is typically used for 64-bit applications. When a user installs a 64-bit application on a 64-bit version of Windows, it goes into this folder.
- Program Files (x86): This directory is designated for 32-bit applications. When a 32-bit application is installed on a 64-bit version of Windows, it is placed in this folder to maintain compatibility with the 32-bit architecture.
This separation helps prevent conflicts between 32-bit and 64-bit applications and ensures that the operating system can manage them effectively.
What is Linux x86_64?
Linux x86_64 refers to the 64-bit version of the Linux operating system that is designed to run on x86_64 architecture, also known as AMD64. This architecture was developed by AMD and extends the original x86 architecture to support 64-bit processing.
Linux x86_64 takes advantage of the increased memory capacity and enhanced performance offered by 64-bit processors. It allows for greater efficiency in executing applications that require significant resources, such as servers, scientific computing, and resource-intensive software development.
We believe this article helps you understand the significance of x86 architecture and its various applications in computing. Grasping these concepts is essential for navigating the world of modern operating systems and hardware.
