BtrfsBtrfs (b-tree file system, commonly read as Butter Fs,better FS or B-tree FS), a file system that supports write-time replication (COW), can consist of multiple underlying physical volumes. In addition, the file system supports RAID, data and meta-data check code (checksum), sub-volume, snapshot and transparent compression function.File

addresses to be modified, it is done by specially designed programs. The disadvantage is that you must allocate a continuous storage area to the job. during the execution of the job, you cannot expand the storage space or move it in the primary storage, it is difficult for multiple jobs to share copies and data of the same program in the primary storage. (2) dynamic relocation. Dynamic Relocation refers to the transformation from logical address to physical address during the running of the pr

1. Let's take a simple look at the concepts related to programs and processes. Program: binary files used by users. Process: Some information related to the program that is loaded into the memory after the program runs. Such as process id pid and memory usage. A program is a static concept. As a software resource, a process is a program execution process. It is a dynamic concept and has a certain life cycle. It is generated and extinct dynamically. There is no one-to-one correspondence between p

: a process derived from a program process is called a sub-process. When the parent process is terminated, the child process also terminates. But the child process is terminated, and the parent process is not necessarily terminated. 2. task management Work Management is the behavior management of multiple jobs simultaneously under a single terminal interface in
