Types of Cache
System cache can be categorized into several types, each serving a specific purpose:
Cache can be divided into two main categories: memory cache and disk cache. Memory cache, also known as RAM cache, stores data in the system’s random access memory (RAM), providing fast access to frequently used applications and data. Disk cache, on the other hand, stores data on the hard drive or solid-state drive (SSD), reducing the time it takes to load applications and files from the disk.
How Cache Works
When a user accesses a file, application, or system resource, the system checks the cache first to see if the required data is already stored. If it is, the system can retrieve the data from the cache, reducing the time it takes to access the original source. This process is known as a cache hit. If the data is not in the cache, the system must retrieve it from the original source, which can take longer. This process is known as a cache miss.
