It is costlier than main memory or disk memory. It is used to speed up the performance while executing a program because it stores frequently used data and instructions so that it is immediately available to the CPU when needed. Cache reduces the average time to locate data from the main memory. How Cache Memory Work Level 1 cache memory is the fastest memory. CPU first check the information in the L1 cache memory. If the information is not stored here, then the CPU will find it in the level 2 cache memory. L2 is slower than L1 cache memory. If still, the information is not present in level 2, then the CPU will search it in the L3 cache memory. Now, the cache returns the data to the CPU. What is Cache Miss? A cache miss occurs when the CPU searches all levels of cache memory to access the data or information, but the data is not available. It is the opposite of cache hit. It does not create any kind of issue because if there is no memory stored in the cache memory, the CPU retrieves it from the main memory. What happens when you clear cache? Clearing cache is 100% safe. When you clear the cache, it only removes temporary files without affecting your personal data. Do not clear the cache unless you have a specific reason to do so. It helps to load the program faster, which is a good thing. If you are facing any glitches, then clearing the cache can help you.
