Caching
Caching is a technique used in computing to store copies of frequently accessed data in a temporary storage location (cache) to reduce latency, improve performance, and decrease load on primary data sources. It involves keeping data closer to the requester, such as in memory or on a local server, to speed up retrieval times. This concept is widely applied in web development, databases, operating systems, and hardware to optimize system efficiency.
Developers should learn and use caching to enhance application performance, especially in high-traffic scenarios where repeated data access causes bottlenecks. It is crucial for reducing database queries, speeding up API responses, and improving user experience in web applications, e-commerce sites, and content delivery networks. Implementing caching can significantly cut costs and resource usage by minimizing redundant computations and network calls.
