Why is the array called a random storage structure?

In computer science, random storage represents access to a random component of a sequence at the same time. The opposite is called sequential access, which means it takes more time to access a remote component.

The array uses a continuous storage space for storage, and the elements are stored one by one. If you know the position of the first element, you can directly know the position of the x-th element, which can be done in O(1 ) time access, which conforms to the definition of random storage, so it is a random storage structure.
