Final answer:
True, the dual caching approach reduces communications traffic via client cache, and disk I/O through server cache. It employs caching on both the client and server sides to improve system efficiency and performance by managing bandwidth and decreasing server workload.
Step-by-step explanation:
True, the dual caching approach is indeed utilized to decrease the amount of communications traffic, achieved through the client cache, and to minimize disk I/O, which is served by the server cache. Essentially, dual caching involves having two levels of caching: one at the client side and another at the server side. By storing frequently accessed data on the client's local cache, the need for repetitive data requests to the server is reduced, which in turn conservatively manages bandwidth and reduces latency.
On the other side, server caching aims to reduce the load on the server's storage system by keeping commonly requested data in a fast-access cache memory, leading to a decrease in disk I/O operations and an improvement in overall performance of the system. Concurrently, this mechanism decreases the workload on the server's main storage, leading to more efficient data retrieval processes and ultimately enhancing the user experience.
