NetApp Senior Engineer Interview Questions, Process, and Tips

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.

• Baseline and benchmark are used to measure and improve performance.

• For example, a company may set a baseline for their websit...read more
