    v. t. e. 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.

    en.wikipedia.org/wiki/Text-based_user_interface

    Vim is a very widely used TUI text editor. In computing, text-based user interfaces ( TUI) (alternately terminal user interfaces, to reflect a dependence upon the properties of computer terminals and not just text), is a retronym describing a type of user interface (UI) common as an early form of human–computer interaction, before the advent ...

  5. C file input/output - Wikipedia

    en.wikipedia.org/wiki/C_file_input/output

    The C programming language provides many standard library functions for file input and output. These functions make up the bulk of the C standard library header <stdio.h>. [1] The functionality descends from a "portable I/O package" written by Mike Lesk at Bell Labs in the early 1970s, [2] and officially became part of the Unix operating system ...

For example, the dir and ls programs (which display file names contained in a directory) may take command-line arguments, but perform their operations without any stream ...

    Programmed inputoutput (also programmable input/output, programmed input/output, programmed I/O, PIO) is a method of data transmission, via input/output (I/O), between a central processing unit (CPU) and a peripheral device, [1] such as a Parallel ATA storage device. Each data item transfer is initiated by an instruction in the program ...

  8. Data dependency - Wikipedia

    en.wikipedia.org/wiki/Data_dependency

    Data dependency. A data dependency in computer science is a situation in which a program statement (instruction) refers to the data of a preceding statement. In compiler theory, the technique used to discover data dependencies among statements (or instructions) is called dependence analysis .

  9. Cross-site scripting - Wikipedia

    en.wikipedia.org/wiki/Cross-site_scripting

    Many operators of particular web applications (e.g. forums and webmail) allow users to utilize a limited subset of HTML markup. When accepting HTML input from users (say, very large), output encoding (such as &lt;b&gt;very&lt;/b&gt; large) will not suffice since the user input needs to be rendered as HTML by the browser (so it shows as ...
