`
`point, index - polymorphic
`
`fractional part of the number may be held
`within a given range, still permitting the
`expression of numbers of greater
`magnitude. (Contrast with point, fixed
`and with point, variable.)
`point, index- In punch-card machines con(cid:173)
`taining rotating machinery driven by a
`main shaft, one of the equally spaced
`rotational reference positions of the main
`shaft. The
`equally
`spaced
`reference
`positions are usually chosen to be those at
`which successive card rows or columns are
`at the sensing or punching station of the
`card reader or punch. Extra index points
`may be required · to allow for a gap
`between cards while they are traversing
`the card track. The index point may be
`labeled according to the row or column, if
`any, to which it corresponds.
`point, interchange- A location, usually in a
`data network, where interface signals are
`transmitted between equipment by means
`of planned electrical interconnection.
`point, load- A marked position on magnetic
`tape that is positioned under the recording
`head when the reel is mounted in a tape
`station. Reading and writing begin and
`end at this point. A metallic strip may be
`used to mark the load point, indicating to
`both the operator and the machine where
`to start or stop reading or writing.
`point, radix-Same as point, arithmetic.
`point, reentry-In a computer program, the
`instruction at which
`the program
`is
`reentered from another program, routine,
`or
`subroutine. The
`reentry point
`is
`usually designated by the address or the
`label of the instruction that is designated
`as the reentry point.
`point, rerun- A location or a point in a
`computer program at which
`all
`in formation
`required
`to
`repeat
`the
`program
`from
`the last rerun point is
`available either to the program itself or to
`a restart routine. This permits repeating
`the
`routine
`from
`the
`last
`rerun or
`checkpoint in the event of an error or a
`malfunction. The rerun points may be
`only thr~e to five minutes apart, so that
`instead of returning to the beginning of a
`program in the event of an error, it is only
`necessary to return to the last rerun point.
`All information pertinent to a rerun is
`available in stored or recorded form during
`the whole time from one rerun point to
`the next. One purpose of a checkpoint is
`to per mit the rerunning of the program
`from the checkpoint; thus, a checkpoin t
`may serve as a rerun point. In any case , a
`computer run may be reconstituted and
`rerun point or a
`run again
`from a
`(Synonymous with restart
`checkpoint.
`point, and with rescue point.)
`point, rescue- Same as point, rerun.
`point, restart-Same as point, rerun.
`point, variable - A radix numeration system in
`which each number is represented by a
`numeral ; that is, a set of digits, with the
`arithmetic point explicitly indicated by a
`character placed among the digits by the
`262
`
`writer according to the magnitude of the
`number desired
`to be expressed; for
`example, 85.96, 8.596, or 859P6. Usually
`the point is a dot or period, and its
`position separates the coefficients of the
`negative powers of the radix from the
`coefficients of the positive powers of the
`radix, being just to the right of the
`coefficient of the zero power of the radix;
`that is, just to the right of the units
`position. (Contrast with paint, floating
`and with point, fixed-)
`point, zero-level tran8mission reference-An
`arbitrarily chosen physical point in a
`circuit to which all transmission levels,
`such as current, voltage, and power levels,
`are referred or referenced, and so are
`measured from. The transmission level at
`the transmitting switchboard is frequently
`taken
`as
`the
`zero-level
`transmission
`reference level, and thus the transmitting
`switchboard becomes
`the
`zero-level
`transmission reference point.
`point-through-The
`transfer of a recorded
`signal from one layer of magnetic tape to
`adjacent layers when the tape is wound
`on a hub or reel.
`point-to-point connection-See connection,
`point-to-point.
`pointer-An identifier or indicator of the
`location of data; for example, an address,
`an algorithm for generating an address, a
`keyword, a code
`for generating an
`address, or a destination or
`source
`designator.
`pointer, stack-The address of the first one
`of a sequence of storage locations that
`are used for a pushdown storage. The
`address is usually held in a preassigned
`stack
`register.
`(Synonymous
`with
`indicator.)
`polarization diversity - See diversity,
`polarization.
`polarized dipole modulation recording- Same
`as recording, polarized return-to-zero.
`polarized
`return-to-zero
`recording- See
`recording, polarized return-to-zero.
`Polish notation-See notation, Po lish.
`poll- I: In switching networks, to request a
`station to send data. 2: In a computer
`operating
`system,
`to
`periodically
`interrogate a device to determine if an
`interaction is required between the device
`doing the polling and the device that is
`being polled. 3: To interrogate a set of
`devices
`sequentially;
`for example,
`to
`interrogate each of a set of terminals
`sharing
`a
`communication
`channel
`to determine if it requires
`periodically
`use of the channel.
`·
`a mode of
`polymorphic-Pertaining
`to
`comp u ting system organ i zation,
`configuration, or arrangement of major
`component parts in a manner such that all
`components at a given installation are held
`in a common pool, and, as each program to
`be executed is selected, a specific set of
`com ponents
`is chosen from
`the pool,
`electrically connec ted, used to execute the
`program, and, upon completion, returned
