`
`mark-to-space ratio Same as mark-space ratio.
`marker 1. Same as mark (I). 2. Same as mark (2). 3. That
`which serves to make a mark (1) or mark (2). 4. On the
`screen of an oscilloscope, a pip which serves to identify a
`reference frequency.
`marker beacon I. A beacon which radiates a specific pattern
`vertically, and which serves to provide positional informa-
`tion to aircraft. Used, for instance, in an instmment landing
`system. 2. A low-powered beacon which assists marine or
`aeronautical navigation.
`
`marker frequency A frequency which serves to distinguish,
`indicate, or identify. For example, that which indicates the
`upper end ofa frequency band.
`marker generator 1. A radio-frequency generator, such as an
`oscillator, which generates markers (4).
`2. A radio-
`frequency generator, such as an oscillator, which generates
`reference pulses, such as those of a specific frequency, dura-
`tion, or amplitude.
`
`Markov model A manner of representing the associations
`between data elements utilizing probability. Used exten-
`sively in voice recognition software.
`markup language A language, such as HTML or XML,
`utilized for transforming unfot-matted text
`into structured
`documents by inserting hyperlinks, tags, and other display
`and formatting instructions.
`
`marquee In computer graphics, a dotted line that frames a
`selected object, such as a picture. When the dots of said line
`move or flash, also called marching ants.
`Marx generator A device which charges tnttltiplc capacitors
`in parallel,
`then discharges them in series. usually using
`spark gaps. Each discharge produces a high—voltagc pulse.
`maser Abbreviation of microwave amplilication by stimu-
`lrttccl omission of radiation. A device whose operation is
`similar to that nfa laser, and which is utilized to amplify or
`generate coherent microwave radiation. Examples include
`gas and solid-state masers. Used, for instance, in communi-
`cations, radio astronomy, radars, and as time and frequency
`standards.
`
`mask 1. An object, stencil, or other device which is applied or
`placed upon a surface, so as to permit the selective passing
`ofpnnicles, beams, rays, substances, and so on, to fonn any
`desired patterns.
`2. The use of a mask (1) to selectively
`shield portions of semiconductor wafers, or other materials,
`during manuf'acturing. Used, for instance, in litltogrnplty. 3. In
`:1 picture tube with R ttrrce«color gun, a grill with round holes
`that is placed behind the screen to make sure that each color
`beam strikes the correct phosphor dot on said screen.
`It in-
`sures, for instance, that the electron beam intended for the
`red phosphor dots only hits those. Also called aperture
`mask, or shadow mask.
`4. To obscure a signal or sound
`with a stronger one. 5. A pattern of bits or characters which
`determines whether another set of bits or characters will be
`selected,
`transmitted, changed, or discarded.
`6. A frame
`which serves to conceal the edges of a CRT.
`mask bit A bit which determines if a conesponding bit will
`be selected, transmitted, changed, or discarded.
`masltnblc interrupt An intcrrttpt which can be disabled by
`another intcrntpt. Such an interrupt may occur. for instance,
`when it there is a serious problem, or if given task or pro-
`gram needs the undividecl attention of the CPU. A non-
`manner.
`mnsknble interrupt is one which can not be disabled in this
`
`masking 1. The use oft: mask. 2. The amount by which the
`threshold of hearing a sound is increased due to the presence
`of another, obscuring sound. The level of masking is usu-
`ally expressed in decibels. Also called masking el'l'ect (1),
`audio mnsltlng, or aural masking. 3. The manner in which
`a signal, property, or pl-tenotnenon is obscured by another.

`Also, the extent to which this occurs. Also called um

`effect (2).
`masking effect 1. Same as masking (2). 2. Same as “ms
`(3).
`masking sound An obscuring sound whose presence
`the threshold ofhearing ofanother, desired sound_ T
`of masking is usually expressed in decibels.

`Used, for instance, as a panel upon which electrical CD
`nents may be mounted.

`
`masquerade To attempt to deceive and/or harm by almmi
`as someone or something else. For example, to send emit .
`with thefrom field using the name of another person or
`tity, or the manner in which a Trojan horse can appear to b..
`a harmless program.

`mass conservation A law whichlstates that mass, or matter,
`cannot be cannot be created nor destroyed in an isolated sys.
`term. For instance, the mass remains constant when a sub.
`stance changes form a solid to a gas in an isolated system.
`This law does not always hold true when dealing with sub-.
`atomic particles. Also called ntnttcr eonscrvtttinn, conser-‘
`vation of mass, or law of nnrss conservation.
`mass-energy equation A fundamental formula for the inter.
`conversion of mass and energy.
`lt is E = me‘, where E .
`energy, m is mass, and c is the speed of light in a vacuum.
`Also called Einstein mass-energy relation.
`mass memory Same as mass storage (1).
`mass number The number of protons and neutrons in th
`nucleus of an atom. For example, the mass number of the
`most common isotope of carbon is 12, as it has 6 protons
`and 6 neutrons.
`Its symbol is A. Also called nucleon num '
`ber.

`mass spectrograph A mass spectrometer in which the :letee- -_i
`tor is a photographic plate. Also called mass spoctroscopc '

`
`mass spectrometer an instrument which idclltilies ions turned
`on their charge-to-mass ratio.
`In it, the sample to be ana-
`lyzed is vaporized. placed in El vacuurn, ionized by an cleo
`tron beam. accelerated by an electric field,
`then deflected -
`into a curved pail! by it rnagnctic Field. The amount ofde-
`'
`tlectioit ofany given ion will depend on its etrarge-to-mass
`ratio, so each diffcrettt species is separntcd according to H5
`mass. A detector records the distribution of each 0| 131°
