sequential access

Sequential access is a method of retrieving data where you read information in a specific order, one piece after another, much like flipping through pages of a book from start to finish. You must go through each item before reaching the desired data, which can be slower for locating specific pieces compared to other methods. This approach is common in storage devices like magnetic tapes, where data is stored linearly. It’s efficient for tasks that process all data sequentially but less so when quick access to individual items is needed.
