    21.​ A system has the following characteristics: Memory Access (read/write) : 50ns disk access : 20ms TLB access : 10ns TLB hit ratio : 90% page fault ratio : 5% You may assume that all page faults require a block to be written. For this system, calculate effective memory access time assuming that 2­level paging is used. Show your work.

    We know that there are different disk allocation methods that help the operating system decide how disk blocks are allocated for files. In the contiguous disk allocation method, each file occupies a set of consecutive addresses on the disk. While this makes file allocation easier, an increase in the file size means that it has to be assigned elsewhere on the disk. The linked disk allocation method requires including a pointer in the current file, which points to the location...

    The VAX/ VMS operating system makes use of four processor access modes to facili-tate the protection and sharing of system resources among processes. The access mode determines:• Instruction execution privileges: What instructions the processor may execute• Memory access privileges: Which locations in virtual memory the current instruc-tion may access The four modes are as follows:• Kernel: Executes the kernel of the VMS operating system, which includes memo-ry management, interrupt handling, and I/ O operations• Executive: Executes many of the operating...
