Scanning techniques are methods used to quickly identify and extract important information from a larger set of data. These techniques are commonly applied in various fields, including computer science, medical imaging, and document processing. By focusing on key elements, scanning helps improve efficiency and saves time when reviewing large volumes of information. In the context of reading, scanning involves glancing through text to find specific details, such as dates or names. This technique is particularly useful for students and professionals who need to locate relevant information without reading every word. Effective scanning can enhance comprehension and retention of essential data.
