Hash collision

Meaning in software engineering, with examples

nounCommon term

In software engineering, hash collision means: A case where two different inputs produce the same hash value.

In Turkish: özet çakışması, hash çakışması

How it is used

Used in hash tables and integrity discussions. A collision does not mean the original inputs are equal.

Example sentences

  1. The map handled the hash collision by comparing the original keys.

    Equal hashes led to an additional equality check rather than replacing the wrong record.

  2. The test deliberately creates a hash collision to exercise the fallback lookup path.

    The test checks behavior when the hash value alone cannot distinguish entries.

Common collocations

  • handle a hash collision
  • hash collision probability
  • hashTo turn data such as a password into a fixed-length string with a one-way function, so that the original value cannot be read back from it.
  • hash mapA data structure that stores key-value pairs and finds the value for a given key very quickly, usually in constant time.
