What is Short-term memory?

Short-term memory is a component of the memory system that holds a small amount of information for a brief period, typically a few seconds to a minute. It acts as a temporary storage space where information is kept active or "online" for immediate use. This memory is limited in both capacity and duration, and unless the information is rehearsed or processed further, it is typically forgotten and replaced by new information. Short-term memory plays a crucial role in cognitive tasks such as reasoning, comprehension, and learning.
