Plug-In B3 Hardware and Software Basics True / False Questions 1. Volatility is a protected memory space created by the CPU allowing the computer to create virtual machines. True False 2. Complex instruction set computer chips limit the number of instructions the CPU can execute to increase processing speed. True False 3. A computer is an electronic device operating under the control of instructions stored in its own memory that can accept, manipulate, and stor...

Chapter 4 - The Abstraction: The Process / Processes Process / Job - A running program. The abstraction provided by the OS of a running program. Virtualizing - The process of running a virtual instance of a computer system in a layer abstracted from the actual hardware. Time Sharing (CPU) - By running one process, then stopping it and running another, and so forth, the OS can promote the illusion that many virtual CPUs exist when in fact there is only one physical CPU (or a few). ...

Temporary data such as function parameters, return addresses, and local variables. What does a stack contain? 1. The parent continues to execute concurrently with its children. 2. The parent waits until some or all of its children have terminated. 3. The child process is a duplicate of the parent process (it has the same program and data as the parent). 4. The child process has a new program loaded into it. When a parent creates a child process what are the possibilities? Context Switch ...

First-Come, First-Served Scheduling correct answers Processes are executed in order received. Convoy Effect - problem where long processes make shorter, potentially more important processes, wait. Shortest Job First Scheduling correct answers Schedule processes/jobs with shortest burst time first. Priority Scheduling correct answers Assign every process a priority Starvation is a risk - low priority processes may never execute. Use aging - increase priority of a process over time...
