Memory Systems: RAM and Cache
Computer memory systems are key to any device’s performance. They help store and access data quickly. RAM and cache are two main types. RAM is volatile and stores data temporarily, while cache is smaller and faster, holding data that’s used often.
RAM gives the CPU quick access to data, making tasks run smoothly. It can hold more data than cache. Cache, being closer to the CPU, is much quicker but holds less.
Random Access Memory (RAM) Explained
RAM comes in types like SDRAM, DDR, and DDR5. DDR4 is popular for its low voltage and high speed. It’s a favourite for today’s devices.
Cache Levels and Their Functions
Cache memory has levels like L1, L2, and L3. Each has its own size and speed. The CPU uses cache before RAM, speeding up access. This boosts system performance by storing often-used data.
Virtual Memory and Swap Space
Virtual memory helps when RAM is full by moving data to disk. This lets systems handle big data and apps, even with limited RAM. In short, RAM and cache are essential for computer efficiency.
| Type of Memory | Description | Access Speed |
|---|---|---|
