Types of Operating Systems

An Operating System performs all the basic tasks like managing files, processes, and memory. Thus operating system acts as the manager of all the resources, i.e. resource manager. Thus, the operating system becomes an interface between user and machine. 

Types of Operating Systems: Some widely used operating systems are as follows- 

1. Batch Operating System – 
This type of operating system does not interact with the computer directly. There is an operator which takes similar jobs having the same requirement and group them into batches. It is the responsibility of the operator to sort jobs with similar needs. 

Advantages of Batch Operating System: 



Disadvantages of Batch Operating System:  

Examples of Batch based Operating System: Payroll System, Bank Statements, etc. 

2. Time-Sharing Operating Systems – 
Each task is given some time to execute so that all the tasks work smoothly. Each user gets the time of CPU as they use a single system. These systems are also known as Multitasking Systems. The task can be from a single user or different users also. The time that each task gets to execute is called quantum. After this time interval is over OS switches over to the next task. 

Advantages of Time-Sharing OS:  

Disadvantages of Time-Sharing OS:  

Examples of Time-Sharing OSs are: Multics, Unix, etc. 

3. Distributed Operating System – 
These types of the operating system is a recent advancement in the world of computer technology and are being widely accepted all over the world and, that too, with a great pace. Various autonomous interconnected computers communicate with each other using a shared communication network. Independent systems possess their own memory unit and CPU. These are referred to as loosely coupled systems or distributed systems. These system’s processors differ in size and function. The major benefit of working with these types of the operating system is that it is always possible that one user can access the files or software which are not actually present on his system but some other system connected within this network i.e., remote access is enabled within the devices connected in that network. 
 



Advantages of Distributed Operating System:  

Disadvantages of Distributed Operating System:  

Examples of Distributed Operating System are- LOCUS, etc. 

4. Network Operating System – 
These systems run on a server and provide the capability to manage data, users, groups, security, applications, and other networking functions. These types of operating systems allow shared access of files, printers, security, applications, and other networking functions over a small private network. One more important aspect of Network Operating Systems is that all the users are well aware of the underlying configuration, of all other users within the network, their individual connections, etc. and that’s why these computers are popularly known as tightly coupled systems

 

Advantages of Network Operating System:  

Disadvantages of Network Operating System:  

Examples of Network Operating System are: Microsoft Windows Server 2003, Microsoft Windows Server 2008, UNIX, Linux, Mac OS X, Novell NetWare, and BSD, etc. 

5. Real-Time Operating System – 
These types of OSs serve real-time systems. The time interval required to process and respond to inputs is very small. This time interval is called response time

Real-time systems are used when there are time requirements that are very strict like missile systems, air traffic control systems, robots, etc. 

Two types of Real-Time Operating System which are as follows: 

Advantages of RTOS:  

Disadvantages of RTOS:  

Examples of Real-Time Operating Systems are: Scientific experiments, medical imaging systems, industrial control systems, weapon systems, robots, air traffic control systems, etc.
