Environment Variable
Environment variables are a set of dynamic named values that can affect the way running processes will behave on a computer.
They can be said in some sense to create the operating environment in which a process runs. For example, an environment variable with a standard name can designate the location that a particular computer system uses to store temporary files – this may vary from one computer system to another. A process which invokes the environment variable by (standard) name can be sure that it is storing temporary information in a directory (folder) that exists and is expected to have sufficient space.

Famous quotes containing the words environment and/or variable:
“In a land which is fully settled, most men must accept their local environment or try to change it by political means; only the exceptionally gifted or adventurous can leave to seek his fortune elsewhere. In America, on the other hand, to move on and make a fresh start somewhere else is still the normal reaction to dissatisfaction and failure.”
—W.H. (Wystan Hugh)
“There is not so variable a thing in nature as a lady’s head-dress.”
—Joseph Addison (1672–1719)
