Array

A computer programming term.

An 'array' is very common data type in computer programs. An array allows you to handle single column lists, double column list and more.

For example a 'one dimesional' array could store a list of names

Index Name
0 John
1 Sarah
2 Henry
3 Emma
4 Tom
and so on.

Notice that most programming languages have the first element of an array at position zero, not 1.
