1. L1 Cache: This is the smallest and fastest cache memory located directly on the CPU chip. It is used to store instructions and data that the CPU is currently working on.
2. L2 Cache: This is a larger cache memory that is located on the CPU chip or on a separate chip close to the CPU. It stores data that is frequently accessed by the CPU.
3. L3 Cache: This is a larger cache memory that is located on the CPU chip or on a separate chip further away from the CPU. It stores data that is less frequently accessed by the CPU.
4. Disk Cache: This is a cache memory that is used to temporarily store data that is being read from or written to a hard disk drive. It helps to improve the performance of the disk drive by reducing the amount of time it takes to access data.

Four Types of Cache Memory
1. Direct-Mapped Cache: Each memory block has a designated cache line in the cache. This is the simplest and most common type of cache.
2. Set-Associative Cache: Each memory block can be stored in multiple cache lines within a set. This improves performance over direct-mapped cache by reducing the probability of cache misses.
3. Fully-Associative Cache: Any memory block can be stored in any cache line. This provides the highest performance but is also the most expensive to implement.
4. Victim Cache: A small, fully-associative cache that stores recently evicted blocks from the main cache. This helps reduce the penalty of cache misses and improves overall performance.
