An engineering team at a motorsport racing event needs to analyze vehicle telemetry data.
The data from the database table lap_telemetry is imported into a program written in a high-level programming language.
The program stores this data in a two-dimensional (2D) string array with the identifier telemetryData.
The data to be stored is shown in the table below:
| LapNumber | DriverCode | Sector | MaxSpeed |
|---|---|---|---|
| 4 | HAM | S1 | 312 |
| 4 | VER | S2 | 325 |
| 5 | HAM | S1 | 315 |
| 5 | LEC | S3 | 210 |
In this table, the value of telemetryData[1, 1] contains "VER".
Because an array can only store data of one data type, any non-string data (such as the integer values representing maximum speed) must be converted to a string before it can be stored in the array.
Identify the computing term used to describe converting a value from one data type to another.
