ISA Slot (Industry Standard Architecture ) (8, 16 Bit)

Industry Standard Architecture (ISA) is a metonym term for the 16-bit internal bus of IBM PC/AT and similar computers based on the Intel 80286 and its immediate successors during the 1980s. The bus was (largely) backward compatible with the 8-bit bus of the 8088-based IBM PC, including the IBM PC/XT as well as IBM PC compatibles.

EISA Slot (Extended Industry Standard Architecture ) (32 Bit)

 

The Extended Industry Standard Architecture (in practice almost always shortened to EISA and is a bus standard for IBM PC compatible computers. It was announced in September 1988 by a consortium of PC clone vendors (the “Gang of Nine”) as a counter to IBM’s use of its proprietary Micro Channel architecture (MCA) in its PS/2 series.

EISA extends the AT bus, which the Gang of Nine retroactively renamed to the ISA bus to avoid infringing IBM’s trademark on its PC/AT computer, to 32 bits and allows more than one CPU to share the bus.

VESA (32 Bit)

The VESA Local Bus (usually abbreviated to VL-Bus or VLB) was mostly used in personal computers. VESA (Video Electronics Standards Association) Local Bus worked alongside the ISA bus; it acted as a high-speed conduit for memory-mapped I/O and DMA, while the ISA bus handled interrupts and port-mapped I/O.

PCI (Peripheral Component Interconnect)

Conventional PCI, often shortened to PCI, is a local computer bus for attaching hardware devices in a computer. PCI is the initialism for Peripheral Component Interconnect and is part of the PCI Local Bus standard. The PCI bus supports the functions found on a processor busbut in a standardized format that is independent of any particular processor’s native bus. Devices connected to the PCI bus appear to a bus master to be connected directly to its own bus and are assigned addresses in the processor’s address space. It is a parallel bus, synchronous to a single bus clock.

AGP (Accelerated Graphics Port)

The Accelerated Graphics Port (often shortened to AGP) is a high-speed point-to-point channel for attaching a video card to a computer system, primarily to assist in the acceleration of 3D computer graphics. It was originally designed as a successor to PCI-type connections for video cards. Since 2004, AGP has been progressively phased out in favor of PCI Express (PCIe); by mid-2008, PCI Express cards dominated the market and only a few AGP models were available.

PCI Express

PCI Express (Peripheral Component Interconnect Express), officially abbreviated as PCIe, is a high-speed serial computer expansion busstandard designed to replace the older PCI, PCI-X, and AGP bus standards. PCIe has numerous improvements over the older standards, including higher maximum system bus throughput, lower I/O pin count and smaller physical footprint, better performance scaling for bus devices, a more detailed error detection and reporting mechanism (Advanced Error Reporting, AER[1]), and native hot-plug functionality. More recent revisions of the PCIe standard provide hardware support for I/O virtualization.
