cached, memfree, and buffers are all memory-related terms in Linux operating systems.
- Cached: This refers to the amount of memory used by the Linux kernel to cache data from the file system. The cached memory can be quickly accessed by the kernel, which can speed up system performance.
- Memfree: This refers to the amount of memory that is currently free and available for use by applications.
- Buffers: This refers to the amount of memory used by the Linux kernel to cache data from I/O operations, such as reading or writing to a disk. Like cached memory, buffered memory can be quickly accessed by the kernel to improve system performance.
When you add these three values together, you get the total amount of memory that is currently available for use by the system.
