A slot may refer to any of the following:

1. When referring to an SD or other memory cards, a slot is the hole the card is placed into. See our card reader term for further information.

2. A slot is an opening for a CD-ROM, DVD, and other disc drive that does not use a tray. See our slot load disc drive definition for further information.

3. A slot is a computer processor connection designed to make upgrading the processor easier, where the user would only have to slide a processor into a slot. The original slot, or Slot 1 (pictured below), was first released by the Intel Corporation in 1997 as a successor to the Socket 8. Later, AMD released another slot processor known as the Slot A in 1999. 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 and are replaced by sockets.

4. A slot is another name for an expansion slot such as an ISA, PCI, AGP slot, or memory slots. See the motherboard definition for a visual example of all of these slots.
