Primary storage is directly accessible by the CPU. It is fast but expensive. Secondary storage is not directly accessible by the CPU and is slower but cheaper.
| Storage Type | Examples | Advantages | Disadvantages |
| Primary Storage | RAM (Random Access Memory), ROM (Read-Only Memory) | Fast access speeds, allows for rapid data retrieval and manipulation. | Volatile (RAM loses data when power is off), expensive. |
| Secondary Storage | Hard Disk Drive (HDD), Solid State Drive (SSD), USB Flash Drive | Large storage capacity, non-volatile (data persists when power is off), relatively inexpensive. | Slower access speeds compared to primary storage, HDDs are susceptible to physical damage, SSDs can be more expensive than HDDs. |
