Complete the sentence to explain what Consistency means in CAP theorem.

DBMS Theory
Consistency means that every read receives the most recent write or an error, ensuring [1] data across all nodes.

Fix the error in the statement about Availability in CAP theorem.

DBMS Theory
Availability means every request receives a response, without guarantee that it contains the most recent [1].

Fill both blanks to complete the explanation of Partition tolerance.

DBMS Theory
Partition tolerance means the system continues to operate despite [1] between nodes, handling [2] in the network.
