Hey there!

The main memory of a computer that includes RAM, ROM, and cached information that is accessible through the CPU is called primary storage. These memory/storage types deal directly with how the computer functions and runs. The other type of storage is called secondary storage and refers to storage that isn't directly connected to the CPU, such as the hard drive.
