Describe the structure of the information-processing system

In the store model of the human information-processing system, information from the environment that we acquire through our senses enters the system through the sensory register.
 The store model: A model of information processing in which information is depicted as moving through a series of processing units — sensory register, short-term memory, long-term memory — in each of which it may be stored, either fleetingly or permanently.
 Sensory register: the mental processing unit that receives information from the environment and stores it momentarily.
 Short-term memory: the mental processing unit in which information may be stored temporarily; the work space of the mind, where a decision must be made to discard information or to transfer it to permanent storage, in long-term memory.
 Long-term memory: the encyclopedic mental processing unit in which information may be stored permanently and from which it may be later retrieved.
