- array: A grid of numbers (a row, a table, or more) that NumPy can do math on all at once.
- broadcasting: NumPy and PyTorch stretching a smaller array to match a bigger one, so you can add a single number or a row to a whole table at once.
- dtype: What kind of number an array holds, such as whole numbers (int64) or decimals (float32). It sets precision and memory use.
