Play an AI-generated podcast conversation about this lesson

What is virtualization?

Virtualization refers to the abstraction of the physical hardware from the operating system.

How are multiple virtual machines (VM) realized in virtualization?

Multiple virtual machines with their own virtual hardware components are isolated from each other on one real physical PC.

Which types of hardware and software can be used for virtualization solutions?

Various types of hardware and software can be used depending on the application area.

What is the main purpose of a hypervisor in virtualization?

The hypervisor is installed in a real PC to enable the realization of multiple virtual machines (VM) with their own virtual hardware components. Signup and view all the answers

What are the two different types of virtualization discussed in the text?

Server-based virtualization (Type 1: Native) and Client-based virtualization (Type 2: Hosted) Signup and view all the answers

What is the hypervisor's role in virtualization?

The hypervisor is the virtualization layer on top of which the VMs run. It manages resource allocation of real hardware and the execution of VMs. Signup and view all the answers

What distinguishes Server-based virtualization (Type 1: Native) from Client-based virtualization (Type 2: Hosted)?

Server-based virtualization runs directly on the hardware of the host, is more efficient, and requires fewer resources. Client-based virtualization operates through a remote client. Signup and view all the answers

Why does Server-based virtualization (Type 1: Native) require all the drivers?

Server-based virtualization runs directly on the hardware of the host, hence it must provide all the drivers. Signup and view all the answers

In what areas of application can Server-based virtualization (Type 1: Native) be used?

Server-based virtualization can be used in data centers, production plants, presentations, and short tests. Signup and view all the answers

What are the main characteristics of client-based virtualization (Type 2: Hosted)?

The hypervisor is based on a full-fledged operating system, VMs are operated directly from the PC via video card and monitor, and main application areas include presentations and short tests. Signup and view all the answers

How does server-based virtualization (Type 1 Native) differ from client-based virtualization (Type 2 Hosted)?

Server-based virtualization runs directly on the hardware of the host, is more efficient, requires fewer resources, and the VMs are operated via remote client. Signup and view all the answers

Explain the role of the hypervisor in client-based virtualization.

The hypervisor in client-based virtualization is based on a full-fledged operating system, such as Windows, and uses the device drivers of the operating system. Signup and view all the answers

What are the main advantages of server-based virtualization over client-based virtualization?

Server-based virtualization is more efficient, requires fewer resources, and runs directly on the hardware of the host. Signup and view all the answers

In which scenarios would client-based virtualization be most suitable?

What is the key difference in how VMs are operated in server-based virtualization compared to client-based virtualization?

In server-based virtualization, the VMs are operated via remote client, while in client-based virtualization, they are operated directly from the PC via video card and monitor. Signup and view all the answers
