The significance of algorithms in data processing lies in their ability to automate decision-making and perform complex computations efficiently. Algorithms provide step-by-step instructions for solving problems or executing tasks, allowing computers to process large datasets quickly and accurately. In data processing, algorithms enable tasks such as sorting, searching, and analyzing data, which are essential for extracting valuable insights. By optimizing algorithms, organizations can improve data analysis performance, enhance predictive models, and support data-driven decision-making.
