The answer is B: installs and runs different versions of an operating system on the same computing device
Virtual machines are like guest operating systems or application environments that give you the perception that you are physically connected to a different box. A system virtual machine, for instance, copies all the components and processes of a real computer. It helps the user experiment with different operating systems and applications without the need to install them on your physical hardware.
A source code editor, hope this helps! :)
Answer:
Yes. Pseudocode is an improvement over the IPO chart because it lays out the sequence of steps for a particular program
Explanation:
The input–process–output (IPO) chart is a widely used approach in systems analysis and software engineering for describing the structure of an information processing program or other process. The chart has three components (Input, Process and Output), and you write the description of each component in plain English, not code or mathematical formulas.
Pseudocode is a procedure for solving a problem in terms of the actions to be executed and the order in which those actions are to be executed.
Pseudocode is an improvement over the IPO chart because it shows the step by step sequence to be followed by a particular program unlike the IPO chart which just break the program into Input, Process and Output.
