A receptacle on a PC motherboard designed to hold Intel microprocessors beginning with the Pentium II Xeon and including the Pentium III microprocessor. Like Slot 1, Slot 2 is encased in Intel’s Single Edge Contact packaging, so it slides easily into the slot on the motherboard. It includes 330 electrical contact points and is slightly wider than Slot 1. It also supports communication between the CPU and the L2 cache at the full clock speed of the PC. See also L2 cache, motherboard, Pentium. Compare Slot 1.
