A searching algorithm is a method used to locate a specific item or record within a collection of data. Searching algorithms are an important part of computer science and are used in many different applications, including database systems, operating systems, and computer networks. There are several types of searching algorithms, including linear search, binary search, and hash search, each with its own set of advantages and disadvantages. Linear search is a simple method that involves iterating through each element in the collection until the desired item is found. Binary search is a more efficient method that involves dividing the collection into smaller segments and comparing the desired item to the middle element of each segment. Hash search involves creating a hash table, which is a data structure that stores items using a hash function to generate a unique key for each item. This allows for faster search times by allowing the search to be performed directly on the key rather than iterating through the entire collection.
