The CAL operating system was begun in the fall of 1968. Within nine months the basic system had been implemented on an off-the-shelf CDC 6400 with extended core storage. Since that time it has been in daily use for further development and experimentation. Since the fall of 1970 it has been available to the Berkeley campus community.

Linux has the ability to support 27 different file systems ranging from minix to a socket file system. To accomplish this Linux uses what is called a VFS or Virtual File System. This system allows several different types of file systems to be mounted under the root directory (/). The data structure used to implement the VFS is called inode.

The system calls available in the interface vary from operating system to operating system. The system call is called by programmer whenever services are required from OS. The process starts running in user mode.
