In computing, Machine Check Architecture (MCA) is an Intel and AMD mechanism in which the CPU reports hardware errors to the operating system.. Intel's P6 and Pentium 4 family processors, AMD's K7 and K8 family processors, as well as the Itanium architecture implement a machine check architecture that provides a mechanism for detecting and reporting hardware (machine) errors, such as: system ...
Two, 16 bit MCA slots (top and middle). At the bottom is an MCA slot for an IBM 8514 card. Micro Channel architecture, or the Micro Channel bus, is a proprietary 16-or 32-bit parallel computer bus publicly introduced by IBM in 1987 which was used on PS/2 and other computers until the mid-1990s. Its name is commonly abbreviated as "MCA ...
MCA allows wireless clients to choose which access points (APs) to communicate with for access to the network, in contrast to single-channel architecture, which gives more control to the centralized network devices such as the wireless LAN controller.
[3] [4] [5] Despite expensive research and development costs on the part of third-party manufacturers of Micro Channel computers—in part due to the expensive licensing fees incurred by IBM in order to allow legal use of their technology—by 1990 most MCA clones were not fully compatible with the Micro Channel architecture or expansion cards ...

Methyl cyanoacrylate (MCA; also sometimes referred to as α-cyanoacrylate or alpha-cyanoacrylate) [3] is an organic compound that contains several functional groups: a methyl ester, a nitrile, and an alkene. It is a colorless liquid with low viscosity. Its chief use is as the main component of cyanoacrylate glues.
The Pioneer PR-7820 was the first mass-produced industrial LaserDisc player, sold originally as the MCA DiscoVision PR-7820. This unit was used in many General Motors dealerships as a source of training videos and presentation of GM's new line of cars and trucks in the late 1970s and early 1980s.
In statistics, multiple correspondence analysis (MCA) is a data analysis technique for nominal categorical data, used to detect and represent underlying structures in a data set. It does this by representing data as points in a low-dimensional Euclidean space .
