  2. Standard streams - Wikipedia

    en.wikipedia.org/wiki/Standard_streams

    Another Unix breakthrough was to automatically associate input and output to terminal keyboard and terminal display, respectively, by default [citation needed] — the program (and programmer) did absolutely nothing to establish input and output for a typical input-process-output program (unless it chose a different paradigm).

  3. Python syntax and semantics - Wikipedia

    en.wikipedia.org/wiki/Python_syntax_and_semantics

    In Python 2 (and most other programming languages), unless explicitly requested, x / y performed integer division, returning a float only if either input was a float. However, because Python is a dynamically-typed language, it was not always possible to tell which operation was being performed, which often led to subtle bugs, thus prompting the ...

  4. IPO model - Wikipedia

    en.wikipedia.org/wiki/IPO_Model

    A computer program is useful for another sort of process using the input-process-output model receives inputs from a user or other source, does some computations on the inputs, and returns the results of the computations. [1] In essence the system separates itself from the environment, thus defining both inputs and outputs as one united ...

  5. Redirection (computing) - Wikipedia

    en.wikipedia.org/wiki/Redirection_(computing)

    command > file1 executes command, placing the output in file1, as opposed to displaying it at the terminal, which is the usual destination for standard output. This will clobber any existing data in file1. Using command < file1 executes command, with file1 as the source of input, as opposed to the keyboard, which is the usual source for ...

  6. Parameter (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Parameter_(computer...

    Further, since in common programming styles most parameters are simply input parameters, output parameters and input/output parameters are unusual and hence susceptible to misunderstanding. Output and input/output parameters prevent function composition, since the output is stored in variables, rather than in the value of an expression. Thus ...

  7. Input/output - Wikipedia

    en.wikipedia.org/wiki/Input/output

    In computing, input/output (I/O, i/o, or informally io or IO) is the communication between an information processing system, such as a computer, and the outside world, such as another computer system, peripherals, or a human operator. Inputs are the signals or data received by the system and outputs are the signals or data sent from it.

  8. SIPOC - Wikipedia

    en.wikipedia.org/wiki/SIPOC

    In process improvement, SIPOC or suppliers, inputs, process, outputs and customers (sometimes in the reversed order: COPIS) is a tool that summarizes the inputs and outputs of one or more business processes in table form, with each of the words forming a column in the table used in the analysis.

  9. Mask generation function - Wikipedia

    en.wikipedia.org/wiki/Mask_generation_function

    Mask generation functions are deterministic; the octet string output is completely determined by the input octet string. The output of a mask generation function should be pseudorandom, that is, if the seed to the function is unknown, it should be infeasible to distinguish the output from a truly random string. [1]
