What is the difference between change and growth?
A change is an exchange,a growing process towards making a difference between two or more variables,while growth is the positive and workable realisation of the change-process.
Statistical process control?
Explain the difference between capability and control.
What is the difference between a random variable and random process?
A random process is a sequence of random variables defined over a period of time.
What are the similarities and different between comparing whole number and comparing decimals?
The process is the same.
What is the difference between poisson distribution and poisson process?
A poisson process is a non-deterministic process where events occur continuously and independently of each other. An example of a poisson process is the radioactive decay of radionuclides. A poisson distribution is a discrete probability distribution that represents the probability of events (having a poisson process) occurring in a certain period of time.
What is a synchronization process mean?
a synchronization manager is a program that can help you synchronizing for ex your computer and a palm The process by which files and programs are transferred between PDAs and PCs.
The provision of mechanisms for process synchronization?
The provision of mechanisms for process synchronization
What is the different between independent and cooperating process?
a process which does not need any other external factor to trigger it is an independent process. a process which works on occurance of any event and the outcome effects any part of the rest of the system is called a cooperating process.
What is semaphore in operating system?
Semaphores are devices used to help with synchronization. If multiple processes share a common resource, they need a way to be able to use that resource without disrupting each other. You want each process to be able to read from and write to that resource uninterrupted. A semaphore will either allow or disallow access to the resource, depending on how it is set up. One example setup would be a semaphore which allowed any number of processes to read from the resource, but only one could ever be in the process of writing to that resource at a time.
In advance operating system what is process synchronization?
In computer science, especially parallel computing, synchronization means the coordination of simultaneous threads or processes to complete a task in order to get correct runtime order and avoid unexpected race conditions. There are many types of synchronization: * barrier * lock/semaphore * non-blocking synchronization * synchronous communication operations advantages of synchronous communications are * no need of start and stop bits * higher data rates possible * the actual data length need not be fixed
Who uses semaphore?
Semaphores are used in computer science for process synchronization. They help control access to shared resources to prevent conflicts between processes running concurrently. Operating systems and programming languages utilize semaphores to manage critical sections of code and coordinate communication between multiple processes or threads.
What do you mean by synchronization in operating system?
synchronization mean arrange all process in sequence for that not occured no colusion in the system.
What is the similarity between semaphore and monitor?
The wait and signal operations on condition variables in a monitor are similar to P and Voperations on counting semaphores. A wait statement can block a process's execution, while a signal statement can cause another process to be unblocked. However, there are some differences between them. When a process executes a Poperation, it does not necessarily block that process because the counting semaphore may be greater than zero. In contrast, when a wait statement is executed, it always blocks the process. When a task executes a V operation on a semaphore, it either unblocks a task waiting on that semaphore or increments the semaphore counter if there is no task to unlock. On the other hand, if a process executes a signal statement when there is no other process to unblock, there is no effect on the condition variable. Another difference between semaphores and monitors is that users awaken by a V operation can resume execution without delay. Contrarily, users awaken by a signaloperation are restarted only when the monitor is unlocked. In addition, a monitor solution is more structured than the one with semaphores because the data and procedures are encapsulated in a single module and that the mutual exclusion is provided automatically by the implementation.(excerpted from http://ei.cs.vt.edu/~cs5204/sp99/monitor.html) The wait and signal operations on condition variables in a monitor are similar to P and V operations on counting semaphores.

What is the name given to the process of signaling with two flags?
Semaphore is one such system.
What is interprocess synchronization?
Processes might need to communicate to each. Interprocess of synchronization is the?æ management of resource among process. It ensures only a single thread (process) access a resource at a particular time.
What is the process by which a WSUS server obtains the updates that it will distribute to clients?
Synchronization!
What is cooperating processing?
cooperating processes are processes that cooperate to achieve a specific task. a task is initially broken into subtasks , each subtask is assigned to a process that should pass the result (or input) to another process and so on , until the task is done.
