What is Dynamic
Introduction
In computer terms, the word dynamic refers to processes, systems, or data that change or can be modified in real-time. It contrasts with static, which implies something fixed or unchanging. Dynamic systems are adaptable, allowing for updates, changes, or modifications without needing a system restart or significant manual intervention.
Examples of Dynamic in Computing
- Dynamic Web Pages: These are web pages that update or change based on user input or real-time data. They often pull information from a database and adapt the displayed content on the fly.
- Dynamic Memory: Dynamic memory allocation allows a system to allocate and free memory at runtime, enabling more efficient resource management.
- Dynamic Data Structures: Data structures that grow and shrink in size during program execution, such as linked lists or dynamic arrays.
Dynamic vs. Static
Dynamic systems or data change as the program or user interacts with them. For example, a dynamic web page may change based on user input, whereas a static web page always displays the same content. Similarly, dynamic memory allocation is adjusted during a program’s runtime, while static memory is pre-allocated and cannot change.
Common Applications of Dynamic Systems
- Web Development: Websites using dynamic content to display personalized information to users, like e-commerce websites with dynamic product listings.
- Programming: Programs that utilize dynamic memory for efficient data handling and adaptable program flow.
- Database Systems: Dynamic databases that allow real-time data entry, modification, and retrieval.
