Operating system is an interface between user and application which you can run on computer system. It is a software component that is responsible for all the management of several activities of computer and helps to share the resources. It hosts various computer security software that can run on your system and handles all the operation of computer hardware. Users can access the services which are offered by operating system. You can interact with OS through graphical user interface knows as GUI and command line interface CLI. Here is an overview about different types of operating systems.
Real-time OS
It is a multitasking OS which aims to execute the real-time applications. It often used the specialized scheduling algorithms that can achieve deterministic nature of behavior. The major object of real-time OS is predictable and quick response of events.
Single-user and Multi-user OS
This type of Computer operating system allow multiple users to access a computer simultaneously. It can be classified as time sharing systems and enable multiple users to access a computer via time sharing. Single-user OS, opposed to multi-user OS are allow one user at a time.
Single-tasking and multi-tasking operating system
When you are allow to run a single drivers download program at one time, then system is grouped in single-task system category, where as the operating system allows to execute multiple tasks at one time, is called multi-tasking operating system.
Distributed Operating System
It manages a group of independent computer system or make them appear to single computer is called as distributed system. These computations are carried out on more than one system.
Embedded System
These operating systems are designed for embedded computer and operate on small machines such as PDAs. They are extremely efficient and compact by design. Moereover, these system can operate with limited number of software download resources.
Mobile OS
It is not distinct kind of OS, it is also an important in the list of operating system types. It is used to control the mobile phones and wireless communication device. Mobile multimedia formats are in-built in it. More so, it can be used in smartphones and tablet PCs.
Interactive and Batch Processing Systems
In batch processing, programs are grouped, collected and processed on later date. In this, input data are processed and collected in batches, is known as batch processing. Whereas, the interactive systems require user intervention. It cannot be executed without the presence of user. To execute any computer security software, there is need of user.
Offline and Online Processing
In online processing, the user have to contact with computer and processes which are executed under the control of central processing unit. When processes are not under the control of CPU, is called offline processing.
