Argument definition An argument is a way for you to provide more information to a function. The function can then use that information as it runs, like a variable. Said differently, when you create a function, you can pass in data in the form of an argument, also called a parameter. Ar...
In programming, instantiation is the creation of a realinstanceor particular realization of an abstraction ortemplate, such as aclassofobjectsor a computerprocess.

Programming is many things to many people, and not everyone agrees on its potential for human learning. This is especially true at a time when even very young children are increasingly ―expert‖ gamers, tweeters, information-seekers, and digital ―bricoleurs‖. Mostly self-taught, or at least...
Here is a look at what a Java package is in programming and how to use them to group classes (and interfaces) together.
A variable, in the context of programming, is a symbolic name given to an unknown quantity that permits the name to be used independent of the information it represents. Variables are associated with data storage locations, and values of a variable are normally changed during the course of prog...
a compiler is a software tool that translates the source code of a program written in a high-level programming language into machine-readable code that can be executed by a computer. as a programmer, you would use a compiler to convert your human-readable code into machine-readable code that...
Many different programs exist to create source code. Following is an example of the source code for a Hello World program in C language: /* Hello World program */ #include<stdio.h> main() { printf("Hello World"); } A person with no background in programming can read the C programming...
In short, OpenFlow is an SDN technology that abstracts and generalizes network processing rules and supports centralized programming. POF Similar to OpenFlow, the architecture of POF includes two parts: the control plane (POF controller) and the data plane (POF Forwarding Element (FE)). POF is...
