A marina keeps a slip spreadsheet with berth ID, length, monthly fee, and occupancy. It also keeps dock-camera video and VHF radio recordings. Which statement correctly names the data types?
Select an answer to reveal the explanation.
Short Explanation
Think of the slip sheet like a grid of cubbies and the dock video like a messy pile of tapes. Rows and columns are structured. Camera footage and radio chatter are unstructured. A filename or a start time does not magically turn media into a table.
Full Explanation
Structured data sits in rows and columns with predefined fields, which is the slip spreadsheet. Unstructured data is free-form content such as video or audio. A filename does not make video structured. Living in a file does not make a table unstructured. A start timestamp on an audio clip does not turn that waveform into a tabular dataset.
