EISA Bus
The Extended Industry Standard Architecture (frequently known by the acronym EISA and pronounced "eee-suh") is a bus standard for IBM PC compatible computers. It was announced in September 1988 by a consortium of IBM PC compatible, PC clone vendors (the Gang of Nine) as an alternative to IBM's Proprietary hardware, proprietary Micro Channel architecture (MCA) in its IBM PS/2, PS/2 series.Compaq Leads 'Gang of Nine' In Offering Alternative to MCA, ''InfoWorld'', Sep 19, 1988. In comparison with the AT bus, which the Gang of Nine Retronym, retroactively renamed to the Industry Standard Architecture, ISA bus to avoid infringing IBM's trademark on its IBM Personal Computer AT, PC/AT computer, EISA is extended to 32-bit computing, 32 bits and allows more than one Central processing unit, CPU to share the bus. The bus mastering support is also enhanced to provide access to 4 gigabyte, GB of memory. Unlike MCA, EISA can accept older ISA cards — the lines and slots for EIS ...

Peripheral Component Interconnect
Peripheral Component Interconnect (PCI) is a local computer bus for attaching hardware devices in a computer and is part of the PCI Local Bus standard. The PCI bus supports the functions found on a processor bus but in a standardized format that is independent of any given 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. Attached devices can take either the form of an integrated circuit fitted onto the motherboard (called a ''planar device'' in the PCI specification) or an expansion card that fits into a slot. The PCI Local Bus was first implemented in IBM PC compatibles, where it displaced the combination of several slow Industry Standard Architecture (ISA) slots and one fast VESA Local Bus (VLB) slot as the bus configuration. It has subsequently been adopted for other computer types ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
