Question

what is concatenation please explain

Answer 1

Concatenation (from Latin concatenare, to link together) is taking two or more separately located things and placing them side-by-side next to each other so that they can now be treated as one thing. In computer programming and data processing, two or more characterstrings are sometimes concatenated for the purpose of saving space or so that they can be addressed as a single item. (Of course, some way may be needed to know how to unconcatenate them later.)
