A program is an executable.
A process is an executable that has been loaded into working memory and is currently executing the program.
A thread is a thread of execution within a process. Every process has at least one thread, but threads can spawn additional threads as required to allow concurrent operations to be performed near-simultaneously.

What is t per inch?
In engineering terms it may be teeth or threads
When you buy a computer program where would you normally find your rights to use the program?
In the license agreement. Usually this is displayed early in the installation process. If you disagree with any of the terms of use, do not install the product.
What is the relation between a thread and a process?
Threads exist within the same process; they can share memory and take less time to perform a "context switch;" they are part of the same program running in parallel processing units. Threads each have their own dedicated memory, and a shared memory area. Processes are entirely partitioned units of executing code. They cannot directly share memory with each other without assistance from the operating system, and are protected from each other by the operating system (in most modern operating systems, that is). They require more time to perform a context switch, as the entire task must be swapped out of the CPU instead of just the thread stack.
What does DZR stand for in Plumbing terms?
Dezinctafication process
What step is data either written to the file or read from the file?
Insertion is the process of writing data to a file. Extraction is the process of reading data from a file. More generally we use the terms output and inputrespectively. However, the output of one process can often be used as the input for another. Therefore the terms must be applied within the context of the objects being read from or written to.
Difference between child process and threads in operating systems?
One difference is that, when the main program terminates, all its threads are terminated. It is not the case for processes, because they are kind independent of the parent. When the parent terminates, the process keeps going unless the parent waits for it to die.
What is the difference between a process and a program?
A program is a set of instructions that tell a computer what to do, while a process is an instance of a program running on a computer. In simpler terms, a program is like a recipe, and a process is like the dish being cooked according to that recipe.
What are process states in operating system?
To put it in simple terms, we write our computer programs in a text file and when we execute this program, it becomes a process which performs all the tasks mentioned in the program. When a program is loaded into the memory and it becomes a process, it can be divided into four sections ─ stack, heap, text and data
What is t per inch?
In engineering terms it may be teeth or threads
What does the graduation start date signify in terms of the commencement of the academic program?
The graduation start date signifies the beginning of the academic program and the official start of the graduation process.
What are the advantages and disadvantages of user level threads and kernel level threads?
User-level threads have the advantage of being lightweight and can be managed without kernel intervention, allowing for faster thread switching. However, they are limited in their ability to utilize multiple processors efficiently and can be blocked by system calls made by a single thread. Kernel-level threads, on the other hand, offer better performance on multi-core systems and can take advantage of kernel features, but they are heavier in terms of resource consumption and switching between threads can be slower due to kernel involvement.

What is the pitch distance of pipe threads?
Pipe threads are stated in terms of so many threads per inch. For instance, a bolt designated as 1/4-20 is a 1/4 inch diameter bolt with 20 threads per inch. Divide one inch by 20 to find the pitch distance.
What is the definition of thread?
A computer runs many applications at once, each instance of an application is known as a process. Each process is made of 1 or more threads, each thread is a sequence of code, this code is often responsible for one aspect of the program, or one task a program has been given. For instance a program doing a complex long calculation may split into two threads, one to keep a user interface responsive, and one (or more) to progress through the lengthy calculation.The catch is that when dealing with one or more threads, whilst it is guaranteed each individual thread will progress through its code in sequence, it is not known where each thread will be relative to each other. That is, one thread may progress more quickly than other threads, this means great care must be taken when two threads access one resource, this is usually done through a mutex.AnswerIn computing terms, a thread is a separate line of execution inside a process which shares the instruction portion of the process, but which has unique data associated with that thread.To use an analogy: let's assume we have to make 10 cakes. A normal process would start with its instructions (the cake recipe), and the data (the ingredients for the 10 cakes), then follow the recipe iterative (repetitively) 10 times in sequence, producing 10 cakes. A threaded model for this would say: "but, making cake 4 does not require the exact same egg being used to make cake 2 (that is, there is an egg (data) for each cake)." So, using threads, each thread would use the same instructions (recipe), but have its own unique data (set of ingredients).The problem with threads (as brought up above) is when they must share some resource. In our example, let's assume we only have 1 oven. So, each of the threads would go about preparing it's cake, then go over to use the oven. The first thread to get there would make a lock (mutex) on the oven to bake its cake. The remaining threads would sit around and wait for the lock (mutex) to be cleared, then one of them would grab it, and bake its cake.
Is there a program that you can insert a list of terms and it will define them?
No.
Why cant a single computer processor execute two or more programs simultaneously?
In simple terms a single processor can only process one machine instruction at a time; it's just not possible to execute two or more instructions simultaneously and therefore not possible to execute 2 programs simultaneously. However, it's not quite as simple as that because a modern processor can have 2 or more cores, in which case it is possible to execute 2 or more instructions simultaneously. However, that's not quite the same thing as executing 2 programs simultaneously as we invariably execute far more threads of execution than we have cores available. Note that a program consists of one or more processes and a process consists of one or more threads of execution. Although it is theoretically possible to execute two threads simultaneously upon two cores, when those cores share the same processor they also share the same L2 cache and that's really only beneficial when both threads share the same process. With 2 independent processors there's a better chance of simultaneous program execution, however it's nigh on impossible to guarantee this unless the system is specifically designed for that purpose. In a multi-processing, multi-threaded environment, task-switching makes it next to impossible for any two independent programs to execute simultaneously because every thread has to yield to waiting threads.
