Knowledge Base

Speed Matters More Than Size
While having more RAM can improve performance, there is a limit. If a system already has sufficient RAM for its tasks, adding more won’t necessarily make it faster. The speed (MHz) and latency (CAS) of RAM also play a crucial role in performance.

RAM Enables Multitasking
The more RAM a system has, the more applications it can run simultaneously without slowing down. High-speed RAM (e.g., DDR5) reduces latency and improves performance in gaming, video editing, and heavy computational tasks.

ROM Can Be Updated
Traditional ROM chips were read-only, but modern types like EEPROM (Electrically Erasable Programmable ROM) allow firmware updates. For example, motherboard BIOS updates use EEPROM to improve system compatibility and security.
