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...

Early Intel processors (e.g., the 8086) did not provide hardware support for dual-mode operation (i.e., support for a separate user mode and kernel mode). As a result, most of the systems implemented on these processors did not support multi-user operation. List and explain one potential problem associated with supporting multi-user operation without hardware support for dual-mode operation. (This is the full question)
To provide hardware, Most modern operating system access the storage devices in 1.system mode 2.user mode 3.both modes 4.other modes

Part 1: A pipelined computer completes instructions more quickly by having more than one instruction at a time "in the pipeline." Explain what problem branch instructions cause with instruction pipelining. Describe one approach to overcoming this problem. Part 2: RISC computers generally execute more instructions per second than CISC computers. Describe the penalty or trade-off paid when adopting the RISC architecture. Part 3: When a cache hit to a cache on the CPU chip occurs on a memory write the...
