Intel 8086 introduced

Intel introduced the 8086 microprocessorA CPU on a single integrated circuit — the heart of personal computers and countless embedded devices. in June 1978 — a 16-bit CPUCentral processing unit — the primary chip that executes program instructions. that became the foundation of the x86Intel's dominant CPU architecture family — the instruction set behind most PCs and servers for decades. architecture.

Why it's here

The 8086 established the x86Intel's dominant CPU architecture family — the instruction set behind most PCs and servers for decades. instruction set that still underpins most desktop and server CPUs.

Why it mattered

IBMInternational Business Machines — a major computer and enterprise technology company since the early 20th century. chose the 8088 for the PCPersonal computer — a computer designed for individual use, especially desktop or laptop machines., making Intel's architecture the industry standard.

What it solved

8-bit CPUs could not address enough memory for growing business applications.
