buffering

Linux, like any other advanced operating systems, is designed to make the most efficient use of system resources, particularly in terms of input/output (I/O) operations. To enhance performance, Linux utilizes techniques known as filesystem caching and buffering. These methods play a crucial role in speeding up operations and making the interaction between software and hardware smooth and efficient. In this article, we'll dive deep into what filesystem caching and buffering are, how they function, and why they are essential for the performance of Linux systems. Filesystem caching, often referred to simply as "caching", is a method used by the Linux kernel to keep frequently accessed data and metadata in main memory (RAM).
