instruction of one process and the instruction of another process are interleaved.ThreadsA process can consist of multiple threads, each running in the context of a process and sharing the same code and global data.Virtual MemoryVirtual memory is an abstract concept that provides an illusion for each process that each process seems to be using main memory exclusively. Each process sees a consistent memory, which is the virtual address space. The address in the figure is increased from bottom to

useful solutions. The solution is given only when the recursion is reached at the lowest level, and then the solution is slowly given by recursive regression steps. (contains a certain abstract meaning)2. In the process of "governance" is also "with the first step • The absolute trust", the direct treatment of the solution to calculate.3. The entire process and the "factorial" recursion is basically the same, just a lot of "points" of the procedure.4. If it is not the problem of the binary tree

called when the main window is loaded to initialize the operation such as the following cases: You can initialize the maximum minimum value for the set form, and so on. private void Form1_Load (object sender, EventArgs e){This. MinimumSize = this. Size;This. MaximumSize = this. Size;This. MaximizeBox = false;} 2. Create a new form Sometimes we need a function, click on the menu and then pop up a new window. The Name property of Window 2 is: Formdisplay At this poin
