Input Buffering
/ˈɪn.pʊt ˈbʌf.ər.ɪŋ/
noun — “the art of letting user input pile up politely before the program grabs it.”
Input Buffering is a technique where data entered by the user or received from an external source is temporarily stored in a memory buffer before the program processes it. This allows programs to handle input efficiently, reducing the number of immediate reads from devices like keyboards, network sockets, or files, and preventing constant interruptions to the CPU.
Parameter
/pəˈræm.ɪ.tər/
noun — “the rules of engagement your functions follow when doing their job.”
Parameter is a variable used to pass information into functions, methods, or procedures in programming. It defines the input a function expects and allows for dynamic behavior based on the data provided. For example, in Python, you might define a function like def greet(name):, where name is a parameter that the function uses to customize its output.
Argument
/ɑːrɡ/
noun — “the tiny rebel in your command line that changes how programs behave.”
Arg, short for argument, in programming and command-line contexts, represents input values or options passed to a program, function, or script to modify its behavior or provide necessary data. For example, in a Unix-like shell, running grep "hello" file.txt passes hello and file.txt as Args to the grep command, telling it what to search for and where.
I/O Stream
/ˌaɪ ˈoʊ striːm/
noun — “the digital river your data floats down.”
I/O Stream (Input/Output Stream) is an abstraction representing a flow of data between a program and an external source or destination, such as a file, device, or another program. Streams provide a uniform interface to read from or write to these resources, letting developers handle data sequentially without worrying about the underlying hardware specifics.
Standard Input
/ˈstændərd ˈɪnpʊt/
noun — “the keyboard’s quiet whisper into your programs.”
Standard Input is the default data stream from which a program reads input, typically connected to the keyboard or another input source. It provides a uniform way for programs to accept data without hardcoding file paths or relying on specific hardware devices. In Unix-like systems, Standard Input is one of the three fundamental streams, alongside Standard Output and Standard Error.
Space-Cadet Keyboard
/ˈspeɪs kædət ˈkiːbɔːrd/
n. "Baroque MIT Lisp-machine keyboard with enough modifier keys to make EMACS feel physically possible."
DirectInput
/dəˈrɛkt-ˈɪnˌpʊt/
n. “A Microsoft API within DirectX for handling input from keyboards, mice, game controllers, and other devices on Windows systems.”
DirectInput is a component of DirectX that provides low-level access to input devices, enabling developers to capture and process user input efficiently. It is commonly used in games and interactive applications where precise input handling, low latency, and support for multiple simultaneous devices are essential.
Key characteristics of DirectInput include:
