A. Operating System maintains the page table for each process. A page table is a data structure used by the operating system to store the mapping between virtual addresses used by a process and physical addresses used by the underlying hardware. Each process has its own page table that maps the virtual address space of the process to the physical memory used by the system.

B. The decision as to which available process will be executed by the processor is determined by the short-term scheduling algorithm. Short-term scheduling is responsible for selecting a process from the pool of ready processes to be executed by the CPU. The goal of short-term scheduling is to allocate the CPU to the process that will execute the fastest and make the best use of system resources. The short-term scheduler is typically invoked frequently, such as after each clock tick or after each I/O operation.
