  2. Swap (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Swap_(computer_programming)

    After swap() is performed, x will contain the value 0 and y will contain 1; their values have been exchanged. This operation may be generalized to other types of values, such as strings and aggregated data types. Comparison sorts use swaps to change the positions of data. In many programming languages the swap function is built-in.

  3. Switch statement - Wikipedia

    en.wikipedia.org/wiki/Switch_statement

    Switch statements function somewhat similarly to the if statement used in programming languages like C/C++, C#, Visual Basic .NET, Java and exist in most high-level imperative programming languages such as Pascal, Ada, C/C++, C#, [1]: 374–375 Visual Basic .NET, Java, [2]: 157–167 and in many other types of language, using such keywords as ...

  4. Test-and-set - Wikipedia

    en.wikipedia.org/wiki/Test-and-set

    A lock can be built using an atomic test-and-set [1] instruction as follows: This code assumes that the memory location was initialized to 0 at some point prior to the first test-and-set. The calling process obtains the lock if the old value was 0, otherwise the while-loop spins waiting to acquire the lock. This is called a spinlock. At any ...

    en.wikipedia.org/wiki/List_of_Java_bytecode...

    This is a list of the instructions that make up the Java bytecode, an abstract machine language that is ultimately executed by the Java virtual machine. [1] The Java bytecode is generated from languages running on the Java Platform, most notably the Java programming language.

  6. Compare-and-swap - Wikipedia

    en.wikipedia.org/wiki/Compare-and-swap

    Is a generalisation of normal compare-and-swap. It can be used to atomically swap an arbitrary number of arbitrarily located memory locations. Usually, multi-word compare-and-swap is implemented in software using normal double-wide compare-and-swap operations. [16] The drawback of this approach is a lack of scalability. Persistent compare-and-swap

  7. Function (computer programming) - Wikipedia

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

    A built-in function, or builtin function, or intrinsic function, is a function for which the compiler generates code at compile time or provides in a way other than for other functions. [23] A built-in function does not need to be defined like other functions since it is built in to the programming language. [24]

  8. Garbage collection (computer science) - Wikipedia

    en.wikipedia.org/wiki/Garbage_collection...

    Stop-and-copy garbage collection in a Lisp architecture: [1] Memory is divided into working and free memory; new objects are allocated in the former. When it is full (depicted), garbage collection is performed: All data structures still in use are located by pointer tracing and copied into consecutive locations in free memory.

    Swap (computer programming), exchanging two variables in the memory of a computer Swap partition, a partition of a computer data storage used for paging; SWAP (instrument) (Sun Watcher using Active Pixel System Detector and Image Processing), a space instrument aboard the PROBA2 satellite
