x86 is a widely used computer architecture for central processing units (CPUs). It has become the dominant architecture for personal computers and servers. The name "x86" is derived from the 8086, an early processor released by Intel®. x86 CPUs use a complex instruction set computer (CISC) design, allowing them to execute multiple instructions in a single cycle. Over the years, the x86 architecture has undergone significant advancements and improvements, making it highly compatible and capable of running a vast array of software applications, contributing to its widespread adoption in the computing industry.
