Detailed explanation-1: -The Magic number 7 (plus or minus two) provides evidence for the capacity of short term memory. Most adults can store between 5 and 9 items in their short-term memory. This idea was put forward by Miller (1956) and he called it the magic number 7.

Detailed explanation-2: -the number of items that can be held in short-term memory at any given time and therefore accurately perceived and recalled after a brief exposure (see chunking).

Detailed explanation-3: -The magical number seven (plus or minus 2) What this magical number represents – 7 plus or minus 2 – is the number of items we can hold in our short-term memory. So, while most people can generally hold around seven numbers in mind for a short period, almost everyone finds it difficult to hold ten digits in mind.

Detailed explanation-4: -George Miller was a psychologist who theorized that short-term memory can hold between five and nine pieces of information. This information can be stored in single units called bits or in groupings called chunks.

Detailed explanation-5: -The concept of immediate memory was made popular by George A. Miller’s (1956) article on capacity limits in information processing, suggesting that it is limited to about seven units.
