A consistent distributed systems are those in which all nodes see the same data at the same time.

 

Eventual Consistency

Hence eventual consistency is a consistency model used to achieve high availability and is a weak consistency model.

offers high availability(low latency) at the risk of returning stale data.

Strong Consistency

will always return the updated value.

offers low availability(high latency) but always returns fresh/updated data.
