The term "386" often refers to the Intel 80386, a microprocessor introduced by Intel in 1985. It was a significant advancement in computer technology, being the first 32-bit processor in the x86 architecture. The 386 allowed computers to handle more memory and perform more complex calculations than its predecessors, leading to improved performance in personal computers. The Intel 80386 supported multitasking, enabling multiple applications to run simultaneously. This capability made it popular for both personal and business use during the late 1980s and early 1990s. The 386 architecture laid the groundwork for future processors, influencing the design of subsequent models in the x86 family.
