Linux Swap Partitions

01. View Swap Space = Free

Cached (cache): refers to the reading of the data stored in memory, when read again, without reading the hard disk and directly from memory read,

Accelerates the reading process of the data.

Buffer: When writing data, the distributed write operation is saved to memory, when the hard disk is written to a certain extent,

Reduced disk fragmentation and repeated seek of hard disks, speeding up the process of writing data.

02. New Swap partition: Fdisk/dev/sdb (same as new partition)
