An Operating System (OS) is an interface between a computer user and computer hardware. An operating system is a software which performs all the basic tasks like file management, memory management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers.
Some popular Operating Systems include Linux Operating System, Windows Operating System, VMS, OS/400, AIX, z/OS, etc.
Following are some of important functions of an operating System.
Memory Management
Processor Management
Device Management
File Management
Security
Control over system performance
Job accounting
Error detecting aids
Coordination between other software and users
Following are some of the most widely used types of Operating system.
Simple Batch System
Multiprogramming Batch System
Multiprocessor System
Desktop System
Distributed Operating System
Clustered System
Realtime Operating System
Handheld System
Kernel
The kernel is a part of the software. It is like a bridge between the shell and hardware. It is responsible for running programs and providing secure access to the machine’s hardware. The kernel is used for scheduling, i.e., it maintains a time table for all processes. And the types of kernels are listed a follows:
Monolithic kernel
Microkernels
Exokernels
Hybrid kernels
Shell
The shell is a part of the software which is placed between the user and the kernel, and it provides services of the kernel. The shell thus acts as an interpreter to convert the commands from the user to the machine code. Shells present in different types of operating systems are of two types: command-line shells and graphical shells.
The command-line shells provide a command-line interface while graphical line shells provide a graphical user interface. Though both shells perform operations, the graphical user interface shells perform slower than the command line interface shells.
Types of shells
Korn shell
Bourne shell
C shell
POSIX shell
