What are the essential properties of the different types of operating systems?
The essential properties of the different types of operating systems are as follows −
Batch Operating system
Jobs with similar needs are batched together and run through the computer as a group by an operator or automatic job sequencer. Performance is increased by attempting to keep CPU and I/O devices busy at all times through buffering, off line operation, spooling and multiprogramming. Batch the large jobs that need little interaction, it can be submitted old for exe and picked up later.
Interactive operating system
The system is composed of many short transactions where the results of the next transaction may be predictable. The response time needs to be short because the user submits and waits for the result.
Time sharing Operating system
This system uses CPU scheduling and multiprogramming to provide economical interactive use of the system. The CPU switches rapidly from one user to another. Instead of having a job defined by spooled card images, each program reads its next control card from the terminal, and output is normally printed immediately to the screen.
Real-time operating system
Often used in a dedicated application, this system reads information from sensors and must respond within a fixed amount of time to ensure correct performance.
Network operating system
It provides operating system features across a network such as a file sharing.
Symmetric Multiprocessing (SMP)
It is used in systems where there are multiple CPUs each running the same copy of the operating system. Communication takes place across the system bus.
Distributed Operating system
This system distributed computation among several physical processors. The processors do not share a memory or a clock. Instead, each processor has its own local memory. They communicate with each other through various communication lines, like high-speed buses or LAN.
Clustered Operating system
A clustered system combines multiple computers into a single system to perform computationally
Handheld
A small computer system performs simple tasks such as calendars, email, and web browsing. Handheld systems differ from traditional desktop systems with smaller memory and display screens and slower processors.
