L-1.4: Types of OS(Real Time OS, Distributed, Clustered & Embedded OS)
Gate Smashers
8 min, 15 sec
The video provides an overview of different types of operating systems: real-time, distributed, clustered, and embedded.
Summary
- Real-time operating systems prioritize immediacy and are divided into hard and soft categories based on strictness of timing.
- Distributed operating systems connect geographically dispersed systems, allowing for load balancing and fault tolerance.
- Clustered operating systems link multiple machines on a local network to act as a supercomputer, increasing computation power.
- Embedded operating systems are designed for fixed functionality devices like microwaves and washing machines and cannot be easily altered.
Chapter 1
Introduction to the video and the types of specialized operating systems to be discussed.
- The video is intended to complete the operating system playlist by covering minor points about specialized operating systems.
- The focus will be on real-time, distributed, clustered, and embedded operating systems.
Chapter 2
Explanation of real-time operating systems, including examples and categories.
- Real-time operating systems are contrasted with batch processing; they require immediate processing.
- Examples include YouTube streaming and missile systems, with the latter being an example of a hard real-time system.
- Hard real-time systems cannot tolerate delays, whereas soft real-time systems can handle minor delays.
Chapter 3
Details on distributed and clustered operating systems and their benefits.
- Distributed operating systems connect machines across the world, offering benefits like fault tolerance and scalability.
- Clustered operating systems link multiple devices to work as one, enhancing processing power.
- The main advantages of these systems are increased availability and the ability to handle faults and scale rapidly.
Chapter 4
Characteristics of embedded operating systems used within devices with fixed functionality.
- Embedded systems are designed for a specific function, such as appliances, and cannot be easily modified.
- The operating system within these devices is known as an embedded operating system.
Chapter 5
Concluding remarks on the significance of the discussed operating systems for exams.
- The video concludes by reassuring that the level of detail provided is sufficient for exams.
- Further details on topics like cloud computing can be studied separately if desired.
