What is cache and how does it work?
Cache refers to a high-speed storage location that temporarily holds data or information, allowing for faster access and retrieval. It acts as a buffer between the main memory and the central processing unit (CPU), storing frequently used data or instructions. When a user requests data, the system first checks the cache for the required information. If the data is found in the cache, it is retrieved directly from there, reducing the time and effort required to access the main memory.
The cache works on the principle of temporal locality, which states that recently accessed data is likely to be accessed again in the near future. By storing this data in the cache, the system can quickly retrieve it when needed, improving overall performance and efficiency. However, over time, the cache can become outdated or filled with unnecessary data, leading to decreased performance and potential errors. This is where clearing the cache comes in, allowing users to remove unnecessary data and optimize their system’s performance.
Why is it necessary to clear cache?
Clearing cache is necessary to remove temporary data that is no longer needed or has become outdated.
