The function takes a single parameter: address, a string representing the Ethereum address to be checked.

The function returns a boolean value: true if the address is valid, meaning it meets the standard format and criteria for a valid Ethereum address, and false if the address is invalid, meaning it does not meet the standard format or criteria for a valid Ethereum address.
