Memory capacity refers to the amount of information that can be stored and recalled by a memory system. In humans, this capacity varies among individuals and can be influenced by factors such as age, health, and cognitive training. Memory capacity is often measured in terms of the number of items or bits of information that can be retained. In technology, memory capacity typically refers to the storage capabilities of devices like computers and smartphones. It is measured in units such as megabytes, gigabytes, or terabytes. Higher memory capacity allows for more data, applications, and files to be stored and accessed quickly.
