Keylogger is a hardware and software-based system in which the typed keys are stored.
The keylogger system always stores the sequence of our typed keys. The hackers use the sequence of the keys and they get passwords.
It is a hardware which is installed in our system. It transfers the sequence of keys by using the computer network to hackers.
Some company fits a built-in keylogger module in the wireless keyboard and then it transfers to the hackers by using networks.
