keylogger consists of a micro controller and a non volatile memory like
flash memory etc. The micro controlling unit works to process the data
and transfer it onto the flash memory. The memory of non volatile form
stores the data even after the power go off. Often, the recording in the
flash memory can be retrieved by entering certain password on to the
text editor of the computer. The memory of the key logging device varies

it utilizes the required no. of bytes of the memory. The range of memory
depends on the choice of the user.

loggers. Actually, more often key logging devices are used to track

that the fact of key stoke tracking should be hidden from the computer
operator. Software key loggers need certain software to be run and
installed in the computer; thus there are many chances that the person
operating the computer can find out that his or her key stroking is
being detected. On other hand, hardware key loggers are free from the
requirement of installing any software etc. so it cannot be detected by
the computer operator or even programmer. That’s why they are beneficial
over the software keyloggers.
