Collision resolution is a method used in computer science to handle situations where two or more data entries attempt to occupy the same space in a data structure, such as a hash table. When this happens, the system must find a way to store the conflicting entries without losing any information. There are several techniques for collision resolution, including chaining and open addressing. In chaining, each slot in the hash table points to a list of entries that hash to the same index. In open addressing, the system searches for the next available slot in the table to store the conflicting entry.
