x86 Architecture

A standard family of instruction set architectures for personal computers and servers.

x86 architecture is based on the Intel 8086 microprocessor. It follows a Complex Instruction Set Computing (CISC) design, meaning it has a large set of instructions that can perform complex tasks. It has evolved from 16-bit to 32-bit (x86) and 64-bit (x86-64). Major manufacturers like Intel and AMD produce x86-compatible processors. It dominates the desktop, laptop, and server markets due to its backward compatibility and vast software ecosystem.
