(ISA) The popular architecture for 1980s and early 1990s personal computer buses, such as the IBM PC,XT, & AT.
A personal computer bus architecture.
An expansion bus that was originally 8 bits wide running at a fixed 4.77 MHz. The width of this bus was expanded to 16 bits and the speed was increased to 8.33 MHz in 1984. The ISA bus has existed since the original IBM XT and can still be found in most modern PCs although there has been a concentrated effort to eliminate this "obsolete" bus for the last few years.
An interface standard for connecting hardware expansion cards to a computer. The typical ISA connection is a slot, or edge-card connector, on the computer’s motherboard allowing devices such as sound cards and telephone modems to be plugged in to the computer.
The data bus still used today by some systems for legacy support for older sound cards and modems.
The very first bus used on PC s, it is slowly being abandoned in favor of the PCI bus. ISA is still commonly found on SCSI cards supplied with scanners, CD writers and some other older hardware. ISDN
ISA) Computer card or the expansion slot that it goes into on a main board that enhances the computer by adding a component (e.g.: video card, sound card, etc). The ISA architecture allows 16 bits at a time to flow between the motherboard circuitry and the expansion slot card and its associated device. See also EISA.
A PC bus standard that allows processors and other circuit cards to communicate with each other. In use for PCs prior to plug-and-play PCI technology.
Industry Standard Architecture is a standard bus (computer interconnection) architecture that is associated with the IBM AT motherboard.
The Industry Standard Architecture (ISA) bus is used in computer systems that adhere to the ISA. The ISA bus supplies the signals for performing the following basic functions of the computer system: Memory I/O Direct memory access (DMA)
The very first bus used on PC s, it is slowly being abandoned in favor of the PCI bus. Some hardware manufacturers still use it, though. It is still very common that SCSI cards supplied with scanners, CD writers, ... are ISA . Too bad. ISDN
Expansion bus commonly used in PCs that controls peripheral components.
A computer system that is is built on the Industry Standard Architecture is one that adheres to the same design rules and constraints that the IBM PC/AT adhered to.
Industry Standard Architecture (in practice almost always shortened to ISA) was a computer bus standard for IBM compatible computers.
