In simple terms, they allow you to multitask better, meaning run multiple programs without experiencing a major decrease in performance.

There are several advantages and disadvantages of having a real time operating system. One disadvantage is unseen errors, an advantage is timing.
- USER LEVEL THREADS Aadvantages: · User-level threads can be implemented on operating system that does not support threads. · Implementing user-level threads does not require modification of operating system where everything is managed by the thread library · Simple representation which the thread is represented by a the thread ID, program counter, register, stack , all stored in user process address space · Simple management where creating new threads, switching threads and synchronization between threads can be done without intervention of the kernel · Fast and efficient where switching thread is much more inexpensive compared to a system call - Disadvantages: · There is a lack of coordination between threads and operating system kernel. A process gets one time slice no matter it has 1 thread or 10000 threads within it. It is up to the thread itself to give up the control to other threads · If one thread made a blocking system call, the entire process can be blocked in the kernel, even if other threads in the same process are in the ready state KERNEL LEVEL THREAD: - Advantages: · Because kernel has the full knowledge of all the threads, scheduler may decide to allocate more time to a process having large number of threads than process having small number of thread, where the kernel threads come useful for intense application - Disadvantages: · Kernel level threads are slow and inefficient, since kernel must manage and schedule all the threads as well as the processes. It requires a full TCB for each thread to maintain information about threads, which results in increasing of overheads and kernel complexity
there are plenty of advantages of proprietary os.u can enjoy the features which others cant have by just accessing net to install ur os..because its not open source operating system

it helps to operate the application software and the system software of hte computer

It is a system software and all the processes in the operating system can be controlled by the user.

Advantages are that you can do many things at once. Disadvantages are that your system will run more slowly with all of the tasks.
Switching to a new operating system can have many benefits. It can be easier to store data or maneuver through information centers.

Advantages of a mobile operating system include convenience, open source platforms being well-supported, and notification ease. Disadvantages include instability, and poor battery quality.
Operating system is a layer between hardware and programs you use (MS Word or so). So its advantage is that it makes your computer work.
