Buffers are temporary memory storage areas used by computer processes to manage data efficiently. They act as input or output queues, holding data until a process is ready to handle it. In most cases, buffers store output from one process and serve as input for another—commonly in the form of file buffers. Simply put, buffers improve system performance by allowing processes to temporarily store and access data in memory, reducing delays and enhancing data transfer efficiency.
Difference between Buffer and Cache
A cache is a high-speed data storage layer that stores frequently accessed disk I/O operations to enhance system performance. When multiple processes access the same files, the system caches portions of those files in memory (RAM) to reduce disk read times. Since RAM is significantly faster than hard drives, disk caching allows faster data retrieval, minimizes I/O latency, and improves overall system efficiency.
