What is difference between Process and Thread?
553841
In a nutshell, a process can contain multiple threads. \n\nIn most multithreading operating systems, a process gets its own memory address space; a thread doesn't. Threads typically share the heap belonging to their parent process. \n\nFor instance, a JVM runs in a single process in the host O/S. Threads in the JVM share the heap belonging to that process; that's why several threads may access the same object. \n\nTypically, even though they share a common heap, threads have their own stack space. This is how one thread's invocation of a method is kept separate from another's. \n\nThis is all a gross oversimplification, but it's accurate enough at a high level. Lots of details differ between operating systems. \n\nWith love

I have a couple of suggestions.  First, I'd install a local FTP server to make sure that the problem really is in the code and not in the speed of your network.  I've included a link to one server below, but you can find others using your favorite search engine.\n\n500MB seems like a very small amount of data.  Are you sure you want to use multi-threading?  Could you start multiple copies of your program?  If you decide to go with threading, I'd upgrade to Visual Basic 2005 if you don't have it already - I included a link to the free version below.\n\nIn VB2005, there's a new component for threading called BackgroundWorker.  I've linked to one example of it's use below -- but MSDN has a lot of material on it, including examples.

Many things can do this.\n\nYour computer hangs when a program is waiting for something to be processed.  When programming, it is important to make sure that the bits of information that need to be processed are small enough so that the delays are short.\n\nAs far as errors, you will need to ask a specific question about a specific error.

Depends on the Operating System. I will mention the two most popular.\n\n In Windoze, create a thread\n In *nix call fork()\n\nThey are all different in some way and have their own set of 'gotchas' be prepared to do a lot of RTFM

are u talking about fork or pthreads

reaction and operation time of a task < allowed delay\n\nnot only how fast can it be done, but can it be done as specific times and can these time be accurately reported.\n\n\nis buffering or queuing of data possible.\nmulti-tasking/priority (can not do everything at same time)

From what I remember ...\n\nThe execution environment refers to the environment, memory, disk space etc as well as environment variables, path= etc, a running (executing) program finds itself in.\n\nOperating Environment refers to bigger issues like how to talk to other processes, what protocols to follow etc.\n\nBut it's been a while ...

In programing, interation usually refers to going through a loop an performing the same operation repeatedly. Usually the data item that is acted upon is indexed by a counter that is incremented each time through the loop.\nCommon constructs are:\nfor (for each), while, do (do/while) loops\n\nRecursion refer to a routine that calls itself. The classic example is a subroutine the computes n! by calling itself to compute (n-1)! and then multiplying by returned value by n.\n\nPseudocode:\nSubroutine Factorial(n)\n{\n  if equals 0, return 1\n\n  if 0 < n, return n * Factorial(n-1)\n}

Threads share a virtual memory mapping, so switching between them does not invalidate the TLB and creating them does not require marking pages copy on write. \n\nDue to the lack of an expensive TLB flush, switching between two threads in the same virtual address space will be quicker then switching between processes (which by definition have separate address spaces and thus require the TLB flush).\n\nThe exact details vary depending on OS and processor type, but the above is more or less correct for X86 style chips running a 1:1 threading model. \n\nRegards, Dan.

could be you have too many processes running in your backgound. Check taskmanager

Try to read the common inside the code.(inside the "/*.... */")\n\nThis function do couple of things:\n1. It is to check the input command.\n2. Set the parent thread to wait. \n3. Create a child thread.\n4. Use the child thread to run the command.

Input-Process-output := data is read in , processed , and the results output. I think you may need a little bit more here , e.g. storage , error handling , operator controls , and so on.

it is Intel's term for massive multi threading or doing multiple processes at the same time...this increases the parallelism of each microprocessor in the system. here are the tech details if you are interested:\nhttp://www.intel.com/technology/hyperthread/

because the proccess isnt closing, you have to go into your task manager and close the java process

Not quite sure if you mean the 'process' of an individual program on a personal computer or the method by which software processes are controlled by an operating system. In any case I've answered both.\n\nFirst of all the definition of process "a series of actions or steps taken in order to achieve a particular end".\n\nIn terms of a software process this can mean anything from the program that collects your email from a POP3 server somewhere to one that controls the images on your monitor.\n\nTaking the email collection program as an example this program would follow a process something like this:\n\n- Contact POP3 server\n- Negotiate login (handshake, swap ID, etc)\n- Check for new email\n- Download new email\n\nNow to the control of software processes on an operating system. \n\nInitiating the above program on a UNIX system for example would start a 'software process'. This process is assigned an identification number called a PID or process ID. Also at this stage the process is assigned system resources, memory/disk space and is queued for processor time (roughly speaking).\n\nFor example (running in background):\n\n$ xosview &\n[1] 11670\n\nUsing the 'ps' command to view running processes:\n\n$ ps\n  PID TTY           TIME  CMD\n  736 tty1      00:00:00  bash\n  743 tty1      00:00:00  startx\n  744 tty1      00:00:00  tee\n  752 tty1      00:00:00  xinit\n  756 tty1      00:00:00  kwm\n  ...\n11670 pts/4     00:00:00  xosview\n11671 pts/4     00:00:00  ps\n\nOf course on a windows system starting a program is much simpler, for instance double-clicking on a program icon. Yet it essentially does the same thing; initiate a software process and assign it a process ID and resources.

You have a lot to learn about the difference between these  three. I'll give the basic differences. In all these three there are more than one program executing at a time. But...\n\nMultiprograming: In multiprogramming systems, the running task keeps running until it performs an operation that requires waiting for an external event (e.g. reading from a tape) or until the computer's scheduler forcibly swaps the running task out of the CPU. Multiprogramming systems are designed to maximize CPU usage.\n\nMultitasking: In computing, multitasking is a method by which multiple tasks, also known as processes, share common processing resources such as a CPU. In the case of a computer with a single CPU, only one task is said to be running at any point in time, meaning that the CPU is actively executing instructions for that task. Multitasking solves the problem by scheduling which task may be the one running at any given time, and when another waiting task gets a turn. The act of reassigning a CPU from one task to another one is called a context switch.\n\nMultiprocessing: Multiprocessing is a generic term for the use of two or more central processing units (CPUs) within a single computer system. There are many variations on this basic theme, and the definition of multiprocessing can vary with context, mostly as a function of how CPUs are defined (multiple cores on one die, multiple chips in one package, multiple packages in one system unit, etc.).\n\nMultiprocessing sometimes refers to the execution of multiple concurrent software processes in a system as opposed to a single process at any one instant.\n\nOk? :)
