question 3 : With the same physical memory and the same initial page assignments as in question 1, how many page faults will occur If Optimal page replacement is used ? Assume the reference string (RS) is the same 0172327103? Time t 0 1 2 3 4 5 6 7 8 9 10 RS   0 1 7 2 3 2 7 1 0 3 Frame 0 0                     Frame 1 1                     Frame 2 2                     Frame 3 3                       please find the below question 1 for reference as stated in question 3 above and please answer question 3 accordingly: question 1 : The physical memory consists of 4 frames: 0 through 3.

Properties of different architectures

Software architectures are the blueprint of a software system. They consist of all components involved in a system, relations between various components, the environment of operation, and the principle used in designing the software. In other words, software architecture shows the organization of different software structures and helps understand their behavior.
