Final Answer:

Although x86-64 hardware can function correctly regardless of data alignment, aligning data is crucial for optimizing performance and ensuring efficient memory access in computer systems.

Step-by-step explanation:

Data alignment involves placing data at memory addresses that are multiples of the data size, such as 4 bytes or 8 bytes. While x86-64 processors can handle unaligned data, aligned data access is more efficient. When data is aligned, it allows the processor to fetch larger chunks of data in a single memory access, enhancing performance. Unaligned data may require multiple memory accesses, leading to increased latency and reduced efficiency. Proper alignment is particularly crucial in performance-critical applications, such as those requiring high-speed data processing or multimedia operations.

Aligning data optimizes memory access for improved performance.
