Chunking refers to the formation of individual units of information into larger units. This is often used as a means of overcoming short-term memory limitations. Chunking is also defined as a memory process whereby related items are grouped together into more easily remembered "chunks” , for example, a prefix and four digits for a phone number, rather than seven unrelated numbers or grouping together of a mobile/cell phone number by three digits rather than memorizing the 10 or 11 unrelated numbers,
