Network caching refers to the process of temporarily storing frequently accessed data or resources on a network to improve performance, reduce latency, and minimize bandwidth usage. In network caching, copies of web pages, files, images, videos, or other content are stored in cache servers strategically placed within the network infrastructure. When a user requests a resource, the caching server first checks if it has a copy of the requested data locally. If the data is available in the cache, it is served to the user directly from the cache server, eliminating the need to retrieve it from the original source. This reduces the load on origin servers, speeds up content delivery, and enhances the overall user experience. Network caching can be implemented at various levels within the network, including web browsers, proxy servers, content delivery networks (CDNs), and caching appliances. By caching frequently accessed content, network caching optimizes resource utilization, improves scalability, and reduces network congestion, making it a vital component of modern network architecture.
