1D a single line (?)
2D a flat shape
3D a cube
1D is just a line
1d has only the length, but 2d has both the length and width
2d+1d= 3d
there is 1d 2d 3d and 4d. 1d are the first five fastest times 2d is the second five fastest times and so on
1d has only the length, but 2d has both the length and width.
it is 1D signal.

1D has vertical bars that are read horizontally, 2D has small squares that are read simultaneously both horizontally and vertically. 2D barcodes can store much more information than 1D barcodes can.
1d array contains single row and multiple columns and 2d array contains multiple row and multiple columns. 2d array is a collection of 1d array placed one below another,while 1d array is simple a collection of elements.
