A standard bus architecture associated with the IBM AT motherboards. It's a limited 8-bit and 16-bit bus, but widely compatible.
bus - ndustry tandard rchitecture bus. It is an unofficial designation for the bus design of the PCs and compatibles. This original bus design allows for various adapter cards (Printed Circuit Boards) to be plugged into expansion slots on the system board (motherboard). Originally introduced with an 8-bit data path on the IBM PCs and PC-XTs, the ISA bus was expanded in 1984 with the PC-AT computer and its 16-bit path, and is now commonly 32 bits.
Computers using the same bus structure and add-in cards as the IBM PC, XT, and AT. Also called classic bus. It comes in an 8-bit and 16-bit version. Most references to ISA mean the 16-bit version. Many machines claiming ISA compatibility will have both 8- and 16-bit connectors on the motherboard.

Instruction Set Architecture. The standard set of instructions which are used by a processor.
Instruction Set Architecture: the published specification of the instructions that a particular CPU implements. It is an important simplifying concept to distinguish between "architecture" (ISA) and "implementation" of a CPU. There are few of the former, many of the latter, and "few" is easier to keep track of. See Brooks and Blauuw for a full treatment of this subject.

( ndustry tandard rchitecture) - The bus architecture that was introduced as an 8-bit bus with the original IBM PC in 1981 and later expanded to 16-bit with the IBM PC/AT in 1984. ISA slots are still found in many PC systems today.
'Industry standard' slots inside your PC for connecting modems, soundcards and other add-ins. ISA slots have been superseded by higher-performance PCI slots, but all PCs include at least some for the sake of compatibility with older add-ins.
An older style of adapter card connection
Industrial Standard Architecture. A standard bus architecture associated with the IBM AT motherboard. ISA allows 16 bits at a time to flow between the motherboard circuitry, an expansion slot card and its associated device(s). ISA slots are no longer used in current computers as they have been replaced in motherboard designs by Peripheral Component Interconnect (PCI) slots.
A type of internal computer bus that allows the addition of card-based components like modems and network adapters. ISA has been replaced by PCI and is not very common anymore. close

Industry Standard Architecture. The data bus still used today by some systems for legacy support for older sound cards and modems.
The bus architecture used in the IBM PC/XT and PC/AT. It's often abbreviated as ISA (pronounced eye-sa) bus. The AT version of the bus is called the AT bus and has become a de facto industry standard. Since the late 80s, the industry has been searching for a successor to the ISA bus, which is not sufficient for modern devices and applications. It now appears that the successor will be the PCI local bus architecture. Most computers made today include both an AT bus for slower devices and a local bus for devices that need better bus performance.
abbreviation for "Industry Standard Architecture"] An older bus standard that is being replaced on newer machines by PCI, although at least one ISA slot is still found on even the newest motherboards to handle legacy cards and peripherals. This will likely changed by the end of 1999.

Industry Standard Architecture. It is a PC architecture based upon three key elements : an 8088 Intel microprocessor, MS-DOS operating system, and an 8 bit I/O bus.Historically, this "standard" has been defined by IBM in its famous PC (in 1981) ; IBM always denied to publish the specifications, and the competitors had to discover them (it was not tricky enough to resist to skill, patience and oscilloscopes) in order to be able to manufacture compatible PCBs, and lastly compatible PCs.
An acronym for Industry Standard Architecture. A well-established bus standard that originated with the IBM AT. See PCI and VESA Local Bus.
ISA is an older technology for connecting computer peripherals (stands for Industry Standard Architecture). Common current devices include modems and sound cards. ISA is much slower than PCI, so PCI devices are generally better if you have a choice. ISA is starting to fade and eventually will be removed entirely. Most motherboards still come with at least one or two ISA slots on them.

Acronym for Industry-Standard Architecture. A 16-bit expansion bus design. The expansion-card connectors in an ISA computer are also compatible with 8-bit ISA expansion cards.
Instruction Set Architecture. The attributes of a digital computer as seen by a machine (assembly) language programmer. ISA includes the processor and input/output instruction sets, their formats, operation codes, and addressing modes; memory management and partitioning if accessible to the machine language programmer; the speed of accessible clocks; interrupt structure; and the manner of use and format of all registers and memory locations that may be directly manipulated or tested by a machine language program. This definition excludes the time or speed of any operation, internal computer partitioning, electrical and physical organization, circuits and components of the computer, manufacturing technology, memory organization, memory cycle time, and memory bus widths.

Industry Standard Architecture. The ISA bus was the generally accepted standard before the introduction of the PCI bus. Older motherboard that have PCI systems do have some ISA buses still. The original ISA standard was used in older PC/XT computers and had an 8-bit databus, 64 kilobyte Input/Output address space, and a speed of 8.333 MHZ. This bus was upgraded to a 16-bit databus when the 286 was introduced. A lot of PCI and even AGP cards are used within the ISA I/O space. the configuration then can be done with the help of the PCI configuration space.
