parameter
n 1: a constant in the equation of a curve that can be varied to
yield a family of similar curves [synonym: {parameter},
{parametric quantity}]
2: any factor that defines a system and determines (or limits)
its performance
3: (computer science) a reference or value that is passed to a
function, procedure, subroutine, command, or program [synonym:
{argument}, {parameter}]
4: a quantity (such as the mean or variance) that characterizes
a statistical population and that can be estimated by
calculations from sample data

Parameter \Pa*ram"e*ter\, n. [Pref. para- -meter: cf. F.
param[`e]tre.]
1. A constant number which is part of a theory, function, or
calculation, whose value is not determined by the form of
the theory or equation itself, and may in some cases be
arbitrary assigned.
[PJC]

2. Specifically:
(a) (Math.) A term applied to some characteristic
magnitude whose value, invariable as long as one and
the same function, curve, surface, etc., is
considered, serves to distinguish that function,
curve, surface, etc., from others of the same kind or
family. --Brande & C.
(b) (Conic Sections) (in the ellipse and hyperbola), a
third proportional to any diameter and its conjugate,
or in the parabola, to any abscissa and the
corresponding ordinate.
[1913 Webster]

Note: The parameter of the principal axis of a conic section
is called the latus rectum.
[1913 Webster]

3. (Science) Any constant number which is required to
calculate values of observed phenomena according to a
theory, but the value of which must be determined by
experiment, and cannot be calculated from the fundamental
assumptions of the theory. In general, a theory which has
a large number of parameters, though it may accurately
predict experimental results, is considered as having less
explanatory power and as being less esthetically pleasing
than a theory with fewer parameters.
[PJC]

4. (Crystallog.) The ratio of the three crystallographic axes
which determines the position of any plane; also, the
fundamental axial ratio for a given species.
[1913 Webster]

5. The limits, guidelines, or assumptions from within which
an activity is carried out; as, new arrivals need to learn
the parameters of the research in our department.
[PJC]

6. (Computers) A variable used in a calculation within a
computer program which must be assigned a value before the
calculation can be performed; as, let's plug in the
parameters and see what the result is.
[PJC]

7. A characteristic or element, especially one used as a
criterion for evaluation or judgment; as, a useful
parameter for determining efficiency.
[PJC]

  • How to pass variable as a parameter in Execute SQL Task SSIS?
    The examples would require parameters that have the following names: The EXCEL and OLED DB connection managers use the parameter names 0 and 1 The ODBC connection type uses 1 and 2 The ADO connection type could use any two parameter names, such as Param1 and Param2, but the parameters must be mapped by their ordinal position in the parameter
  • 编程中,parameter、argument翻译成什么中文最好? - 知乎
    但实际上 Argument 专用于 Actual Argument(实际参数,实参),Parameter 专用于 Formal Parameter(形式参数,形参)。 在上下文没有歧义的情况下,我个人的习惯会将这两个词均翻译为参数,在其他情况下使用实参和形参来对 Argument 和 Parameter 加以区分。
  • How are parameters sent in an HTTP POST request?
    parameter=value also=another When you use a file upload in the form, you use the multipart form-data encoding instead, which has a different format It's more complicated, but you usually don't need to care what it looks like, so I won't show an example, but it can be good to know that it exists
  • Why would one ever use the in parameter modifier in C#?
    why shouldn't I make every parameter an in? Well, suppose you made an int parameter instead an in int parameter What costs are imposed? the call site now requires a variable rather than a value; the variable cannot be enregistered The jitter's carefully-tuned register allocation scheme just got a wrench thrown into it
  • Difference between terms: option, argument, and parameter?
    A parameter is an argument that provides information to either the command or one of its options, e g in -o file, file is the parameter of the -o option Unlike options, whose possible values are hard coded in programs, parameters are usually not, so the user is free to use whatever string suits his her needs
  • Difference between parameter and localparam - Stack Overflow
    Any parameter declaration appearing in such a list between a localparam keyword and the next parameter keyword (or the end of the list, if there is no next parameter keyword) shall be a local parameter Any other parameter declaration in such a list shall be a nonlocal parameter that may be overridden
  • Using parameters in batch files at Windows command line
    %0 is the program name as it was called %1 is the first command line parameter %2 is the second command line parameter and so on till %9 parameters passed in on the commandline must be alphanumeric characters and delimited by spaces Since %0 is the program name as it was called, in DOS %0 will be empty for AUTOEXEC BAT if started at boot time
