Access control is often a system enabling authorities to manage access to areas and resources in a given physical facility or computer-based information system. Access control is, the truth is, a standard, everyday phenomenon. For example, a lock on a car door is essentially a type of access control. The PIN over a bank's ATM system is another kind of access control. Even nightclub bouncers, waiting in front of the door, are another instance of (perhaps) a far more primitive mode of access control. Using an access control mechanism is vital when persons look to secure confidential, important, or sensitive information and equipment.

If the volume is loud, there is damage to the baby's hearing. In addition, the earbuds of the earphone are directly inserted into the ear, the sound stimulates the eardrum directly, and then through the eardrum, the time is long, the eardrum is very easy to fatigue, and it can also cause hearing loss. So, when the baby listens to music and listen to the story, it's better to use the outside, and the volume is not too loud.
