What is the primary difference between Type 1 and Type 2
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
hypervisors?
Type 1 hypervisors are used for desktop virtualization, while Type
|\ |\ |\ |\ |\ |\ |\ |\ |\
2 hypervisors are used in data centers.
|\ |\ |\ |\ |\ |\ |\
Type 1 hypervisors are less efficient but easier to install than
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
Type 2 hypervisors.
|\ |\
Type 1 hypervisors run directly on the host system's hardware,
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
while Type 2 hypervisors run on top of the host operating system.
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
Type 1 hypervisors are known for their performance, scalability,
|\ |\ |\ |\ |\ |\ |\ |\ |\
and security, while Type 2 hypervisors are ideal for enterprise
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
virtualization deployments. - CORRECT ANSWERS ✔✔Type 1 |\ |\ |\ |\ |\ |\ |\
hypervisors run directly on the host system's hardware, while
|\ |\ |\ |\ |\ |\ |\ |\ |\
Type 2 hypervisors run on top of the host operating system.
