These are three steps of memory process.

1. The Memory Process

2. The Memory Process
The memory process consists of following three steps.
Encoding
This is the first step of memory process. When we get the
information for the very first time, this type of memory refers
towards encoding. Three different ways of encoding are given
below:
Visual Encoding: It gets the information through
images.
Acoustic Encoding: It involves the encoding of
information through sounds.
Semantic Encoding: In this type, encoding has been
done through the meaning of information.

3. The Memory Process
Storage
This is the second step of memory process in which information is
rehearsed with the passage of time.
Retrieval
This is the last step of memory process in which stored
information is recalled with distinct intervals of time.

4. The memory process consists of these three steps encoding,
storage and retrieval. These three steps are used in human
beings to store and retrieve the memory. In my opinion, the use
of images to store and retrieve information is considered more
effective.
