In the system below, main memory is divided into blocks, where each block is represented by a letter. Two blocks equal one frame. A) How many bits are in a virtual address for process P? Explain. B) How many bits are in a physical address? Explain. That would be used by the system to translate to a physical address and then translate this virtual address into the corresponding physical address. (Hint: convert 18 to its binary equivalent and divide it into the appropriate fields.) Explain how these fields are used to translate to the corresponding physical address.
