Definitions beginning with M

A film of dimensionally stable plastic, to which are adhered carefully graded abrasive or polishing powders, i.e., particles, having dimensions in the micrometer or submicrometer range. Note: Microfinishing films resemble sandpaper, but have much smaller abrasive or polishing particles. They are used commercially to shape and/or polish machined parts. They are also used to finish the endfaces of certain types of optical connectors. [After FAA]

A small base of code running at the highest hardware privilege level. A microkernel is responsible for sharing CPU and memory (and sometimes other devices) between less privileged tasks running on the system. This is similar to a VMM, particularly a <##paravirtualization>paravirtualising VMM but typically addressing a different problem space and providing different kind of interface.

A physical or logical connection established between a remote microprocessor and mainframe host computer for the express purpose of uploading, downloading, or viewing interactive data and databases on-line in real time. Note: A micro-mainframe link usually requires terminal emulation software on the microcomputer.
