| Modern Operating System |
Huge lines of code, a huge number of unnecessary features are not only good characteristics of a modern operating system. There are many features and functions of the operating system discussed below.
Object-Oriented Design
An object-oriented operating system is an operating system that uses object-oriented design principles.
Multi-threading
An application or program divided into the number of smaller tasks, these tasks executed by the processor concurrently(at a time). These smaller tasks are called threads. A thread is a lightweight process and dispatchable unit of work.
A thread has some of the characteristics of a process, but the difference is several threads sharing the same memory space, the process doesn't share the memory space. For example, when we type a document in MS-Word, typed text can be formatted automatically, spelling check automatically, these individual tasks are called threads.
Process and Threads in Operating System
Symmetric Multiprocessing
If a computer has more than one processors, these processors can share the same memory, data path, and I/O facilities, and the processors share the same job for execution, then the system is called a symmetric multiprocessing(SMP).
Distributed Operating System
A distributed operating system is an operating system that runs on a network of computers. The operating systems, memory files are shared by the number of users in the same network from the server. Read more about Distributed Operating System
Microkernel Architecture
A microkernel is a minimal operating system that performs only the essential functions of an operating system. System processes perform all other operating system functions. Here the system process means servers. A system which contains the servers is called a client-server model.
Traditional Unix System
The rapid growth of Unix is due to many factors, i.e., its portability to a wide range of machines, adaptability, simplicity, wide range of tasks it can perform, its multi-user and multitasking nature, and suitability for networking.
The main features of Unix operating system are discussed below
- Ability to support multi-user and multitasking.
- Excellent network environment.
- Adaptability and simplicity.
- It provides the better security.
- Flexible file system.
I hope you have cleared about the characteristics of the modern operating system.
