What is the difference between numeric and non-numeric keys in RDBMS?
Numeric means a number is used. For a key, that would usually be an integer. Non-numeric keys can include any symbols (i.e., text). In theory, you could also use other specialized data types, for example, dates. Check the data types available by a specific RDBMS; details may vary. Almost any data type can be used for a key; although variable-length data types such as BLOB are either not supported or not practical to use.

Why numeric keypad separately in computer keyboard?
because once you learn to type numbers on the numeric keypad, you can type them much faster, good for people who have to do a lot of calculations on their computers.
