Well, I don't know whether you've noticed but in Spring a young man's fancy turns to thoughts of love. When the girls start wearing their summer dresses a man's heart beats a little faster. That is the comfort we feel when Spring (April) replaces winter.
- 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

Like the ending of a mystery story, an enquiry enables the various threads of the story to be brought out and knotted together. The various characters reveal the secret information they have been hiding and gradually the whole picture becomes clear. The way Shakespeare does this is typical of his comedies, particularly those based on misunderstandings, such as The Comedy of Errors, Twelfth Night, and most spectacularly, Cymbeline. It is another way in which Romeo and Juliet, although clearly a tragedy, is written using the conventions of comedy.
No, NPT threads are not compatible with NPSM threads. A pipe with NPT threads tapers slightly, while an NPSM-threaded pipe does not taper.
There are two main kinds of threads implementations: User-space threads and Kernel-supported threads. Mikaela
Plumbing pipe threads are squared and conduit pipe threads are tapered.
The long threads are called the warp and the shorter cross threads are called the weft.
Internal threads are threads inside of a hole in something. Like a nut, for instance. External threads are threads on the outside of a cylindrical object. Like a bolt, for instance. hth, Steve
