ISA Slots

Above is a picture of three ISA slots. These are used for adding ISA expansion cards. ISA stands for Industry Standard Architecture. PCIe and PCI slots are newer and faster than ISA slots. They have replaced the older ISA standard. Below is an ISA card made by Promise called the I/O Max. It has an additional set of serial ports, an additional parallel port, and another IDE connector all on the same card.
