A marine research institute uses an automated database to track its fleet of autonomous underwater drones (AUVs). For each AUV, the system currently stores its unique serial number, maximum depth rating (in meters), and the date of its last safety inspection as variables in each drone's record.
State two other items of data that would need to be stored as variables for each individual drone in this database system.
159 exam-style questions on Edexcel GCSE Computer Science Algorithms, covering Constructs for solving problems, Variables, constants and data structures, Arithmetic, relational and logical operators, Tracing algorithm output with trace tables, Types of error and correcting logic errors, Standard algorithms (sorts and searches), and Evaluating algorithm fitness and efficiency. Each one has a worked solution and a mark scheme showing where the marks go.
