Computer programming languages allow us to give instructions to a computer in a language the computer understands. Just as many human-based languages exist.
These languages allow computers to quickly and efficiently process large and complex swaths of information. For example, if a person is given a list of randomized numbers ranging from one to ten thousand and is asked to place them in ascending order, chances are that it will take a sizable amount of time and include some errors.
There are dozens of programming languages used in the industry today.
