DYNAMIC BIND Meaning and
Definition
-
Dynamic bind refers to a process in computer programming that determines the specific method or function to be executed at runtime based on the actual type or properties of an object or variable. It is a type of late binding where the exact implementation or operation is resolved during program execution rather than at compile time.
In dynamic binding, the decision on which method to call or which function to execute is made based on the actual object or variable at runtime, rather than relying on the declared or static type. This enables more flexibility and adaptability in the program as it can select different operations based on the changing nature of the program's state. The determination of the appropriate implementation is typically done through a process called method dispatch or function resolution.
One common usage of dynamic binding is in object-oriented programming languages, where polymorphism is utilized. Polymorphism allows objects of different classes to be treated as instances of a common superclass, and dynamic binding ensures that the correct method is called based on the specific subclass that an object belongs to.
Overall, dynamic bind is a powerful concept in programming that allows for the selection of the appropriate method or function based on the actual runtime elements, enhancing flexibility and adaptability in software design and execution.
Etymology of DYNAMIC BIND
The term "dynamic bind" is derived from two words, namely "dynamic" and "bind".
1. Dynamic: The word "dynamic" is derived from the Greek word "dynamikos", meaning "powerful" or "pertaining to force". It entered the English language in the 19th century and originally referred to forces or power in motion. Over time, its meaning expanded to include concepts like energy, vitality, change, or being active and dynamic.
2. Bind: The word "bind" has roots in Old English, originating from the word "bindan". It means to fasten, tie, or connect something together. The word has been in use for centuries to refer to the act of joining or restricting something.
"Dynamic bind" combines these two terms to express a concept related to programming or software development.
