The Intel 80286, introduced in 1982, was a significant advancement in microprocessor technology. It was the first processor in the x86 architecture to support protected mode, allowing for better multitasking and memory management. This capability enabled operating systems to run multiple applications simultaneously without crashing, making it a popular choice for personal computers. The 80286 operated at clock speeds ranging from 6 to 25 MHz and could address up to 16 MB of RAM. It was widely used in early IBM PCs and compatible systems, paving the way for more powerful processors like the Intel 80386. Its impact on computing helped shape the future of personal and business computing.
