2.3 Types of operating systems

Batch OS is the first operating system for second-generation computers. This OS does not directly interact with the computer. Instead, an operator takes up similar jobs and groups them together into a batch, and then these batches are executed one by one based on the first-come, first, serve principle.

2. Distributed OS

In a distributed OS, various computers are connected through a single communication channel. These independent computers have their memory unit and CPU and are known as loosely coupled systems. The system processes can be of different sizes and can perform different functions.

3. Multitasking OS

The multitasking OS is also known as the time-sharing operating system as each task is given some time so that all the tasks work efficiently.  This system provides access to a large number of users, and each user gets the time of CPU as they get in a single system.

4. Network OS

Network operating systems are the systems that run on a server and manage all the networking functions. They allow sharing of various files, applications, printers, security, and other networking functions over a small network of computers like LAN or any other private network.

5. Real-time OS

Real-Time operating systems serve real-time systems. These operating systems are useful when many events occur in a short time or within certain deadlines, such as real-time simulations.

Types of the real-time OS are:

• Hard real-time OS

• Soft real-time OS

6. Mobile OS

A mobile OS is an operating system for smartphones, tablets, and PDA’s. It is a platform on which other applications can run on mobile devices.
