Multi-core processing and it’s origins

Modern computers work using the parallel computing style, where a single task or process is broken down a bit before it’s worked on.  A process like explorer.exe is broken into instructions done in functional units.  Several partially completed instructions are worked on at a time, and merged in an assembly line fashion into a single data stream, aka a process.  Until the mid 2000’s this was only seen in supercomputers and business grade mainframe type machines, but the IBM Stretch in 1962 is when pipeline computing took parallel computing to the next level, and lead to chips from the intel Core 2 series in the mid 2000’s, to modern single die intel i9 with 18 cores and 36 threads.
