Parity is calculated by counting the number of 1s in a binary sequence.
Parity is used to detect errors in data transmission.
Even parity means the number of 1s in the sequence should be even.
Odd parity means the number of 1s in the sequence should be odd.
Parity can be calculated using XOR operation on the binary sequence.
Baseline is the starting point of performance measurement while benchmark is the standard for comparison.
Baseline is the initial measurement of performance used as a reference point for future comparisons.
Benchmark is the standard or best practice used for comparison with the current performance.

A transaction in Java is a unit of work that is performed as a single, indivisible operation.

Transactions are typically used in database operations to ensure consistency.
In Java, transactions are commonly implemented using frameworks like Spring's @Transactional annotation.
