Consider the following table. \[ \begin{array}{|c|l|} \hline \textbf{Component} & \textbf{Description} \\ \hline I.\ \text{Solid State Drive} & A.\ \text{Volatile main memory that holds data currently in use by the OS and applications} \\ \hline II.\ \text{Cache Memory} & B.\ \text{High-speed buffer memory between the CPU and RAM that holds frequently accessed data} \\ \hline III.\ \text{Random Access Memory (RAM)} & C.\ \text{ Fastest and smallest storage available for processor computations} \\ \hline IV.\ \text{CPU Registers} & D.\ \text{ Long-term, non-volatile storage used for the operating system and large files } \\ \hline \end{array} \] Which of the following options is the correct match between the entries (I-IV) and the descriptions (A-D)?
Let's analyze and match each memory component to its description: - **I. Solid State Drive**: This is secondary, non-volatile storage used for keeping data long-term, including the OS and personal files. This matches **B**. - **II. Cache Memory**: This is a high-speed SRAM buffer located near the CPU to store frequently accessed instructions, bridging the speed gap between RAM and the CPU. This matches **D**. - **III. Random Access Memory (RAM)**: This is the primary volatile memory that holds applications and data currently active. This matches **A**. - **IV. CPU Registers**: These are the absolute fastest and smallest memory locations situated inside the processor core for immediate computation. This matches **C**.
