Function keys are the set of keys located at the top of the keyboard and range from F1-F12 or F1-F19 in some computers. Every key has a different function to perform and it can be programmed in such a way to cause the operating system by providing it with a command to perform significant actions. Usually, they have been provided with the default actions. Sometimes the keys can work individually and sometimes, they work in unison with different keys on the keyboard such as Esc, Alt, etc. They are usually taken into considerations for keyboard shortcuts and by each key, you can perform a different role.
