  2. Mask (computing) - Wikipedia

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

    To configure IP addresses on interfaces, masks start with 255 and have the large values on the left side: for example, IP address 203.0.113.129 with a 255.255.255.224 mask. Masks for IP ACLs are the reverse: for example, mask 0.0.0.255. This is sometimes called an inverse mask or a wildcard mask. When the value of the mask is broken down into ...

  3. Bit manipulation - Wikipedia

    en.wikipedia.org/wiki/Bit_manipulation

    Source code that does bit manipulation makes use of the bitwise operations: AND, OR, XOR, NOT, and possibly other operations analogous to the boolean operators; there are also bit shifts and operations to count ones and zeros, find high and low one or zero, set, reset and test bits, extract and insert fields, mask and zero fields, gather and ...

  4. Boolean operations on polygons - Wikipedia

    en.wikipedia.org/wiki/Boolean_operations_on_polygons

    Modern implementations for Boolean operations on polygons tend to use plane sweep algorithms (or Sweep line algorithms). A list of papers using plane sweep algorithms for Boolean operations on polygons can be found in References below. Boolean operations on convex polygons and monotone polygons of the same direction may be performed in linear ...

  5. Bitwise operation - Wikipedia

    en.wikipedia.org/wiki/Bitwise_operation

    In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits.It is a fast and simple action, basic to the higher-level arithmetic operations and directly supported by the processor.

  6. 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]

  7. Boolean network - Wikipedia

    en.wikipedia.org/wiki/Boolean_network

    A Boolean network is a particular kind of sequential dynamical system, where time and states are discrete, i.e. both the set of variables and the set of states in the time series each have a bijection onto an integer series.

    public class Shadow {private int myIntVar = 0; public void shadowTheVar {// Since it has the same name as above object instance field, it shadows above // field inside this method. int myIntVar = 5; // If we simply refer to 'myIntVar' the one of this method is found // (shadowing a second one with the same name) System. out. println (myIntVar); // prints 5 // If we want to refer to the ...
