What Does Single Edge Contact Cartridge (SECC) Mean?

A Single Edge Contact Cartridge (SECC) is a central processing unit (CPU) component designed to hold certain Intel microprocessors such as Pentium II and Pentium III, Pentium Pro and Celeron. The SECC is also known as Slot 1 because it is inserted into Slot 1 on the motherboard.

Slot 1 is in reference to the electrical and physical specifications of the connector for both single- and dual-processor configurations of the various Intel microprocessors. It was designed to remove L2 cache memory off the motherboard onto the CPU for better efficiency and scalability. The card was easily inserted into Slot 1 and eliminated the chance of pins being broken or bent as with older socket versions.
