DROPDOWN QUESTION
1 min • 1 pt
A (a) might run software that allows other (b) to behave as if it were running on a (c) : this is called a (d) or VM. A VM can be configured to replicate any combination of (e) so that the software running on it works as if it were accessing certain devices, even if they don't exist.
host system
software
hardware system
virtual machine
hardware
private system
video game system
web service
virtual microsystem
potato
Answer explanation
A host system runs software that allows other software to behave like it's on a virtual machine (VM). The VM can simulate hardware, enabling software to function as if it accesses specific devices, even if they are not present.

DRAG AND DROP QUESTION

Virtual machines can fulfil many roles, including:
(a) : A VM can be created to allow the installation of one operating system within another operating system.
(b) : Some older software might not run on newer systems. A VM could emulate an older system, on which the user could run the older software.
(c) : This provides the opportunity to run software that could potentially be damaging, such as malware or early versions of software that need to be analysed.
Running alternative operating systems
Supporting incompatible software
Creating a test system
Legacy OS
Legacy operating systems
Answer explanation
Virtual machines can run alternative operating systems, support incompatible software, and create test systems. This allows users to install one OS within another, emulate older systems, and safely analyze potentially harmful software.

DRAG AND DROP QUESTION
1 min • 1 pt
Effectively, a virtual machine runs the existing OS (called the (a) operating system) and oversees the virtual hardware using a (b) operating system.

host
guest
emulation
hypervisor
hardware
software
computer
Windows
Apple
compilation
Answer explanation
In a virtual machine setup, the 'host' operating system runs on the physical hardware, while the 'guest' operating system runs within the virtual environment. The 'hypervisor' is the software that manages the virtual hardware, mapping it to the physical 'hardware'.
