Slot

1. A type of computer processor connection designed to make upgrading the processor much easier, where the user would only have to slide a processor into a slot. The original slot, or slot 1, was first released by the Intel Corporation. Later, AMD released another type of slot known as the Slot A. Both slots look similar but are not compatible.  Later, Intel released the slot 2, which was a bigger slot used with the later versions of the Pentium II processors. Today, slot processors are no longer found in new computers.
