the capacity of memory

Memory capacity refers to the amount of information a device or system can store. Think of it like a bookshelf: a larger capacity means more books (data) can fit at once. For computers, capacity is often measured in bytes—such as gigabytes (GB) or terabytes (TB)—where bigger numbers mean more storage. For example, 8 GB of RAM helps a computer run multiple programs smoothly, while a 1 TB hard drive can hold millions of photos, music, or documents. Overall, capacity determines how much data a device can hold at any given time.
