Please refer to this textbook: “A. Silberschatz, P. B. Galvin and G. Gagne, “Operating System Principles,”7th Edition, John Wiley & Sons Inc., 2006.” And answer the following questions: Question:22 Assume Program X and Program Y run in different processes. At some time point, the two programs need to exchange data with each other. A. Can the data exchange be made as efficient as if the two programs were run by different threads in the same process? If so, explain how this can be done. If not, please describe the technical issues. B. If Y needs to wait for X, explain how this can be achieved with a semaphore.
(MAC) In the MAC address table, MAC addresses are stored in a dynamic RAM. Assume the table was 8000 bytes in size and the memory access time was 100 nanoseconds. What would be the worst-case look-up time if a binary search was employed to locate an address?

A memory has 8 megabytes of cells(a) What is the size of its MAR?(b) If 2-dimensional addressing is used, what is the size of each of the horizontaland vertical decoders?
Exercise 8 The speed of the connection between a computer’s memory and its processor often determines the speed of the computer, because instructions often can be executed faster than they can be moved to the processor for execution. This connection is called the von Neumann bottleneck; it is the limiting factor in the speed of computers. True or False
