Memory & Storage
There are a lot of memories in the computer. They can be divided into 2 big categories: internal memeory and external memory. The big difference between them is to see if the CPU exchanges data directly.
Internal memory (Directly)
- Register: Embedded into CPU, used to save the temporary data.
- Cache: Embedded into CPU, as a buffer used to coordinate the speed between CPU and RAM.
- RAM (Random Access Memory): main memory. Inside data will be deleted after cutting off the electricity.
- ROM (Read-Only memory): main memory. used to record the basic I/O information. Inside data will NOT be deleted after cutting off the electricity.
External memory (Indirectly)
- HDD (Hard Disk Drive)
- SDD (Solid State Disk)
- Cloud Storage
