  2. Attribute (computing) - Wikipedia

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

    An attribute in a relational database can be represented as a column or field. In computing, an attribute is a specification that defines a property of an object, element, or file. It may also refer to or set the specific value for a given instance of such. For clarity, attributes should more correctly be considered metadata. An attribute is ...

  3. Context switch - Wikipedia

    en.wikipedia.org/wiki/Context_switch

    Then the operating system calls the switch() routine to first save the general-purpose user registers of A onto A's kernel stack, then it saves A's current kernel register values into the PCB of A, restores kernel registers from the PCB of process B, and switches context, that is, changes kernel stack pointer to point to the kernel stack of ...

    In the context of Visual Basic and Ada, Sub, short for subroutine or subprocedure, is the name of a callable that does not return a value whereas a Function does return a value Object-oriented languages such as C# and Java use the term method to refer to a member function of an object

    OpenMP (Open Multi-Processing) is an application programming interface (API) that supports multi-platform shared-memory multiprocessing programming in C, C++, and Fortran, [3] on many platforms, instruction-set architectures and operating systems, including Solaris, AIX, FreeBSD, HP-UX, Linux, macOS, and Windows.

  6. Object-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Object-oriented_programming

    An object is a data structure or abstract data type containing fields (state variables containing data) and methods (subroutines or procedures defining the object's behavior in code). Fields may also be known as members, attributes, or properties. Objects are typically stored as contiguous regions of memory.

  7. Multiprocessing - Wikipedia

    en.wikipedia.org/wiki/Multiprocessing

    Multiprocessing is the use of two or more central processing units (CPUs) within a single computer system. [ 1 ] [ 2 ] The term also refers to the ability of a system to support more than one processor or the ability to allocate tasks between them.

  8. Barrier (computer science) - Wikipedia

    en.wikipedia.org/wiki/Barrier_(computer_science)

    For example, thread 1 with state value is 0 means it's stopping at the barrier, thread 2 with state value is 1 means it has passed the barrier, thread 3's state value = 0 means it's stopping at the barrier and so on. [5] This is known as Sense-Reversal. [1] The following C code demonstrates this: [3] [6]

  9. Python (programming language) - Wikipedia

    en.wikipedia.org/wiki/Python_(programming_language)

    The syntax :=, called the "walrus operator", was introduced in Python 3.8. It assigns values to variables as part of a larger expression. [105] In Python, == compares by value. Python's is operator may be used to compare object identities (comparison by reference), and comparisons may be chained—for example, a <= b <= c.
