ISA is a type of bus used in PCs for adding expansion cards. For example, an ISA slot may be used to add a video card, a network card, or an extra serial port. The original 8-bit version of PCI uses a 62 pin connection and supports clock speeds of 8 and 33 MHz. 16 …
ISA bus architecture. The 16-bit AT bus slot originally used two standard edge connector sockets in early IBM PC/AT machines. However, with the popularity of the AT-architecture and the 16-bit ISA bus, manufacturers introduced specialized 98-pin connectors that integrated the two sockets into one unit.

The function of expansion slots are exactly like their name. They are meant to hold extra devices. They “expand” your systems ability to have hardware. What is the main function of the isa slot? Same as any other slot, to allow the board to work with the card in the slot. Very outdated slot.
PC Magazine Tech Encyclopedia Index – Definitions on common technical and computer related terms. motherboards provided a mix of both 8-bit and 16-bit ISA slots. As PCI became popular

ISA (Industry Standard Architecture) is a standard bus (computer interconnection) architecture that is associated with the IBM AT motherboard. It allows 16 bits at a time to flow between the motherboard circuitry and an expansion slot card and its associated device(s). Download this free guide.
PCI Slot. Definition – What does PCI Slot mean? A Peripheral Component Interconnect (PCI) slot is a connecting apparatus for a 32-bit computer bus. These tools are built into the motherboards of computers and devices in order to allow for the addition of PCI devices like modems, network hardware or …
Below is a graphic of what an ISA expansion card may look like as well as the slot it connects into on the motherboard. How can I add an ISA card if I don’t have an ISA slot? To connect an ISA card to a computer the motherboard must have an ISA slot. As mentioned above, today’s computers no longer come with ISA expansion slots and most modern operating systems no longer support ISA.
An expansion slot is a socket on the motherboard that is used to insert an expansion card (or circuit board), which provides additional features to a computer such as video, sound, advanced graphics, Ethernet or memory. The expansion card has an edge connector that fits precisely into
History. The EISA bus slot is a two-level staggered pin system, with the upper part of the slot corresponding to the standard ISA bus pin layout. The additional features of the EISA bus are implemented on the lower part of the slot connector, using thin traces inserted into the insulating gap of the upper / ISA card card edge connector.
Superseded by: PCI (1993)
Generally, PCI Express refers to the actual expansion slots on the motherboard that accept PCIe-based expansion cards and to the types of expansion cards themselves. PCI Express has all but replaced AGP and PCI, both of which replaced the oldest widely-used connection type called ISA.
PCI-based AGP portsPCI & ISA Slot Computers by EVS ComputersIn isa slot definition and function computing, the expansion card, expansion board, adapter card or accessory card is a printed circuit board that can be inserted into an electrical connector, or expansion slot, on a computer motherboard, ..
• In this chapter, you will learn to – Identify the structure and function of the expansion bus and ISA slots are shown Cascaded 8259s The 8259 chips were designed to run in a cascade to provide more IRQs – Controlled only the functions specific to VL-bus devices…relying on the ISA slot
PCI (Peripheral Component Interconnect) is an interconnection system between a microprocessor and attached devices in which expansion slots are spaced closely for high speed operation. Using PCI, a computer can support both new PCI cards while continuing to support Industry Standard Architecture ( ISA ) expansion cards, an older standard.
This article will discuss the function and assignment of IRQs, DMAs and Base Addresses (IOPorts) used by IBM compatible computers. It is a “tap on the shoulder” to the CPU by a peripheral card plugged in an ISA slot to tell the CPU that the peripheral has something to say (also used by EISA and MCA slots).
