The following statements describe the basic CPU organization. Select all TRUE statements. Question 4 options: a The program counter (PC) holds the address of the next instruction to be fetched from Memory. b Buses serve as communication highways for passing information. c The instruction register holds each instruction fetched from memory. d The arithmetic logic unit (ALU) carries out arithmetic and logical operations, such as addition, comparison, Boolean AND/OR/NOT, etc.

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: Question4: If event A has a Lamport timestamp of 2 and event B has a Lamport timestamp of 3, you are certain that: A happened before B if the events took place on the same process. A happened before B regardless of the processes on which A and B took place. A and B are concurrent. B happened before A, regardless of the processes on which A and B took Place

Determine the blanks for the following table, circle answer

What are the first two actions while carrying out an instruction?

This is from assembly language and computer organization. Could you also explain for each one how you would move them and replace the word after the comma?

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:25 For the Dining-Philosophers Problem, if a philosopher always picks the chopstick on the right-hand side first and then picks the chopstick on the left-hand side, would a deadlock situation still occur? If so, please give an example. If not, please provide the reason.

answer the following question

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.
