Media Interface Connector (MIC)
Media Interface Connector (MIC). A type of head on a fiber-optic cable that has locking
wings on the sides.
megabyte (MB). A unit of measurement equal to 1,048,576 bytes (1024 kilobytes). See also
gigabyte (GB)
, kilobyte (KB), and terabyte (TB).
member. In a structured programming language, an addressable entry within a data
structure. A member can be a simple field or a data structure.
memory-exact point. A potential breakpoint location within an accelerated object file at
which the values in memory (but not necessarily the values in registers) are the same
as they would be if the object file were running in TNS interpreted mode or on a TNS
system. Most source statement boundaries are memory-exact points. Complex
statements might contain several such points: at each function call, privileged
instruction, and embedded assignment. Contrast with register-exact point
and
nonexact point
.
memory manager. An HP NonStop™ operating system process that implements the paging
scheme for virtual memory. This process services requests generated by different
interrupt handlers as well as by other system processes.
memory page. A unit of virtual storage. In TNS systems, a memory page contains 2048
bytes. In TNS/R systems, the page size is determined by the memory manager and
can vary, depending on the processor type.
memory slot. A physical, labeled space for a memory unit or a dual inline memory module
(DIMM). Memory slots are located on the processor board of an HP NonStop™
S-series processor multifunction (PMF) customer-replaceable unit (CRU).
memory unit. A unit consisting of a dual inline memory module (DIMM) or a single inline
memory module (SIMM) that is installed in groups of four on the processor and
memory board (PMB) of the processor multifunction (PMF) customer-replaceable unit
(CRU) in an HP NonStop™ S-series server. Memory units constitute the processor
memory. The memory units in certain models of PMF CRU are not replaceable by
customers or in the field.
message monitor process (MSGMON). A helper process for the ServerNet cluster monitor
process (SNETMON) that runs in each processor on every node of a ServerNet
cluster. MSGMON is started by the persistence manager process, $ZPM. It performs
duties for SNETMON in those instances where SNETMON needs an agent in each
system processor. In addition, MSGMON monitors the connections within the
processor and reports changes back to SNETMON when required.
method. An object-oriented term for a function, procedure, or routine.
MFIOB. See multifunction I/O board (MFIOB).
MIC. See Media Interface Connector (MIC).
