The Samsung wave was the first mobile to use the bada operating system. Compilers and editors run in user mode, whereas operating system code runs in kernel mode. Linux Shell with examples on files, directories, permission, backup, ls, man, pwd, cd, linux, linux introduction, chmod, man, shell, pipes, filters, regex, vi etc. In the uniprogrammming systems like MS DOS, when a process waits for any I/O operation to be done, the CPU remains idol. Multiuser capability: Multiple users can access the same system resources like memory, hard disk, etc. JavaTpoint offers too many high quality services. The first Android device was launched in 2008. Bada (Samsung Electronics): Bada is a Samsung mobile operating system that was launched in 2010. Operating system: Linux is just the kernel. It manages all the available drivers such as display, camera, Bluetooth, audio, memory, etc., required during the runtime. This component is embedded in the computer system's main memory and may interact directly with the system's H/W. Operating System. Linux is a UNIX based operating system.
