CAP theorem - Availability and Partition Tolerance

Question

While I try to understand the \"Availability\" (A) and \"Partition tolerance\" (P) in CAP, I found it difficult to understand the explanations from various articles.

Answer 1

Consistency – When we are sending the read request, if it is returning result, it should return the most recent write given by client request. Availability – Your request for read/write should always succeed. Partition tolerance – When there is network partition (problem for some machines to talk with each other) occurs, system should still work.

In a distributed there are chances that network partition will occur and we cannot avoid “P” of CAP. So we choose between “Consistency” and “Availability”.
