CAP Theorem Proof

The CAP Theorem states that in distributed systems, you can only achieve two out of the following three things at once: Consistency (all nodes see the same data at the same time), Availability (every request gets a response), and Partition tolerance (the system continues to function despite network failures). In other words, if there's a network issue splitting the system, you must choose between keeping data consistent or ensuring that users can still access the system. This balance is crucial in designing reliable systems, highlighting inherent trade-offs in achieving data management goals.
