Encoding
Encoding is the process of recieving and consolidating a memory or fact. It is usually recieved through one of the 5 senses and consolidated by removing extraneous information.

Storing
Storing is the process of putting the memory or fact with all of your other memories. People with Alzheimer's usually cannot complete this step.

Retrieval
Retrieval is the process of finding the memory/fact that has been already stored. Sometimes, after this step, the process is repeated, if something new and related to it is learned. For example: 1+1=2, 2-1=1.

There are two subtypes of this memory. The first subtype is short-term memory, which is for facts that have to do with the task at hand. All that you just learned about the three steps of memory is in your short-term memory. If the information is relevant enough for you to keep, it will be moved to long-term memory.
