Explanation: 

Detailed explanation-1: -By some estimates, short-term memory can hold around seven items of information at one time. Information can move from short-term memory into long-term memory, where the brain permanently stores the information for future recall when necessary.

Detailed explanation-2: -The duration of short term memory seems to be between 15 and 30 seconds, according to Atkinson and Shiffrin (1971). Items can be kept in short term memory by repeating them verbally (acoustic encoding), a process known as rehearsal.

Detailed explanation-5: -Short-term memory (STM) refers to systems which provide retention of limited amounts of material for a limited time period (seconds).
