- Commonly used in servers and mainframes.
- Examples include Unix and Linux distributions like CentOS.

3. Real-time OS:
- Designed to process data as it comes in, without buffering delays.
- Used in applications like medical devices, industrial systems, and robotics.
- Examples include VxWorks and QNX.

4. Embedded OS:
- Built for specific devices like smartphones, tablets, and IoT devices.
- Optimized for low power consumption and limited hardware resources.
- Examples include Android, iOS, and FreeRTOS.

5. Network OS:
- Designed to manage network resources and communication between computers.
- Used in routers, switches, and network servers.
- Examples include Cisco IOS and Juniper Junos.

Each type of operating system has its unique features and capabilities, catering to different computing needs and environments. Understanding the various types of operating systems can help users choose the right OS for their specific requirements.
