IBM's proprietary icro hannel rchitecture is the data bus of their PS/2 line of microcomputers. This is the data bus of the computer that controls the flow of data between processors and to and from such peripheral devices as the keyboard, monitor, and printer. The Micro Channel has three main aspects: a 32-bit bandwidth, the I/O processors, and the multimaster control, which acts like a data traffic cop to allow multiprocessors to work simultaneously. Boards that plug into the MCA bus are not interchangeable those of standard PCs.
This is a 32-bit standard developed by IBM for expansion cards. The standard offered improvements over 16-bit ISA, but never caught on outside of IBM computers. The industry chose to go with EISA, which was only found in servers and workstations for the most part, and was eventually replaced by PCI.
Stands for "Micro Channel Architecture." It is an expansion bus created by IBM ...

Micro Channel Architecture. IBM's bus architecture developed for the Personal System/2 computer.
Developed by IBM for its line of PS/2 desktop computers, Micro Channel Architecture is an interface between a computer (or multiple computers) and its expansion cards and their associated devices.
Micro Channel Architecture. The MCA bus was introduced in the mid-80s by IBM to replace the ISA bus. Clearly superior to ISA, it was 32-bits wide, supported bus-mastering and provided for "jumper-less" configuration (early Plug and Play). It eventually failed, however, because IBM choose to make the MCA bus incompatible with ISA, which had a large install base.
Micro Computer Architecture, an alternate slot design used in early computers to provide 32 bit access, also the bus associated with such slots.
MicroChannel Architecture
A16/32bit expansion medium designed by IBM
An acronym for Micro Channel Architecture. Developed by IBM for the PS/2 line of computers and introduced in 1987. Features a 16 or 32 bit bus width and multiple master control. By allowing several processors to arbitrate for resources on a single bus, the MCA was optimized for multitasking, multiprocessor systems.
Micro Channel architecture. The basis for the IBM Micro Channel bus, used in high-end models of IBM's PS/2 series of personal computers. See also EISA
Micro-Channel Architecture MCA is a motherboard communication interface used by IBM in some IBM PS/2 computers. It is technically superior to the standard ISA architecture for most uses, but it was poorly marketed, and is quickly disappearing.
An MCA (Micro Channel Architecture) bus slot is a 32-bit expansion slot which was developed by IBM, but was never accepted as an industry standard.

micro channel architecture. Bus interface commonly used in PCs and some UNIX workstations and servers.
Abbreviation for Micro Channel Architecture. A 32-bit proprietary expansion bus first introduced by IBM in 1987 for the IBM PS/2 range of computers and also used in the RS/6000 series. MCA is inco ... more
