MMCs

MMCs is an acronym with multiple meanings across fields. The most common are Metal Matrix Composites, Microsoft Management Console, and Multimedia Card; the intended meaning depends on context.

Metal Matrix Composites are composite materials featuring a metal matrix reinforced with ceramic particles or fibers. They offer higher strength and stiffness with lower weight, and often improved wear and high-temperature performance. Common matrices include aluminum, magnesium, and titanium; reinforcements include silicon carbide, alumina, and carbon fibers. Processing can be challenging and costly, and machinability may be reduced. Typical manufacturing methods are powder metallurgy, casting with reinforcements, and diffusion bonding.

Microsoft Management Console is a Windows framework that hosts administrative tools in modular snap-ins. It provides a single interface for managing local and remote computers, services, policies, and devices. Administrators customize consoles by adding or removing snap-ins such as Event Viewer, Device Manager, and Group Policy Editor. The MMC architecture supports scripting and remote management, and it has been part of Windows since Windows 2000.

Multimedia Card is a memory card standard developed by SanDisk and Siemens in the 1990s. It served as a common removable storage medium for mobile devices before SD cards became dominant. MMCs are older and largely superseded by SD and microSD formats, though the term can still appear in embedded systems and legacy devices.
