ISA is the precursor to PCI. Standing for "Industry Standard Architecture" It was common from the early 1980s to the mid 1990s. ISA was a typically inelegant solution for the time, and required one to know exactly what one was doing- PnP was rare, even for so called "ISA PnP" peripherals. In the end, the combination of flexibility, ease of use, and greater capability allowed PCI to supersede ISA.
An ISA slot is an early type of expansion slot used to connect peripheral cards to a computer's motherboard. ISA stands for Industry Standard Architecture. The original ISA bus slot was 8-bit to coincide with the 8-bit data width of the Intel 8088 processor. In 1984, when the 80286 was introduced, the bus width was doubled to 16 bit. When 32 bit buses were required, the ISA slot was superseded by the PCI slot.
ISA expansion slots are 8-bit and 16-bit bus slots found in older computers. They were first introduced in the original IBM PC (8-bit only) in 1981. 16-bit ones were introduced in the IBM PC AT in 1984. Because of the PC 99 standard introduced by Intel and Microsoft, computers introduced after January 1, 2000 cannot have ISA slots and be certified to run Windows at the same time, so they are only found in older or special-purpose hardware these days.
An ISA card is an expansion card that connects to a computer via an ISA expansion slot. They were introduced on the original IBM PC in 1981, and phased out of most desktop systems entirely by 2000.
The ISA slot started as 8-bit, and then evolved to 16-bits.
The original IBM compatible parts used an 8-bit ISA slot. After that, they moved to a 16-bit ISA slot. There were other things like a VESA slot that didn't last for long. Then there were PCI slots (not express), and AGP was a faster video card slot standard. Then PCI-express replaced both PCI and AGP.

An ISA slot may be used to add a video card, a network card, or an extra serial port. By the end of the twentieth century, ISA ports were beginning to be replaced by faster PCI and AGP slots. Now, most computers only support PCI and AGP expansion cards.

The now obsolete AGP slot was used solely for video. The current slots used for video, the large x16 PCIe connectors, can also be used for general PCIe expansion cards. Sitting in shelf above my head, I still have some PCI and ISA slot video cards: using a general-purpose expansion slot for video is the standard way, and a dedicated graphics expansion slot was a short-term abberation.
To play 3 or 4 players on Hydro Thunder you need a Expansion Pak in your expansion slot.
Same as any other slot, to allow the board to work with the card in the slot. Very outdated slot.
