Radio Button:
A radio button or option button is a graphical control element that allows the user to choose only one of a predefined set of mutually exclusive options
Checkbox:
A checkbox is a GUI widget that permits the user to make a binary choice, i.e. a choice between one of two possible mutually exclusive options.
Difference between Radio Button and Checkbox:
There is a fundamental difference between them. In a checkbox group, a user can select more than one option. Each checkbox operates individually, so a user can toggle each response "on" and "off." Radio buttons, however, operate as a group and provide mutually exclusive selection values.
