Computer - Primary Memory

🧠Architectures and Applications of Primary Computer Memory This video details the fundamental role of *primary memory* in computing, focusing on its high-speed, direct communication with the *CPU**. It explains how computer storage is organized into a **hierarchy* where performance speed directly correlates with increased costs. The source breaks down the primary category into *RAM**, which is fast and **volatile**, and **ROM**, which provides **non-volatile* storage for essential startup instructions. Within these categories, it differentiates between specific technologies like *DRAM* for general use and specialized versions like *VRAM* or *EEPROM**. Finally, it highlights **cache memory* as a critical tool for optimizing processing efficiency by storing frequently used data for rapid access.
