Single Edge Contact (SEC):-
Pentium- II\III chips are characterized by their single edge contact SEC cartridge design. The processor, along with several l2 cache chips, is maintained on a small circuit board (much like an oversized memory SIMM), which is than sealed in a metal and plastic cartridge. The cartridge is then plugged into the motherboard through an edge connector called slot, 1 that looks very to an adopter card slot.
