Searching algorithms are methods used to find specific data within a collection, such as a list or database. They help locate items efficiently, whether it's a number in a sorted array or a word in a text file. Common types include linear search, which checks each item one by one, and binary search, which divides the collection in half to quickly narrow down the search. These algorithms are essential in computer science and programming, as they optimize the process of retrieving information. Understanding how different searching algorithms work can improve performance in applications like search engines and databases, making data retrieval faster and more efficient.
