   operating systems, it's a kernel developed by VMWare Company.
2. The VMKernel can't boot it by itself, so that it takes the help of the 3rd party 

    operating system. In VMWare case the kernel is booted by RedHat Linux operating

    system which is known as service console.
3. The service console is developed based up on Redhat Linux Operating system, it is

    used to manage the VMKernel

How VMWare Kernel different from other kernels?

What is the use of VMWare workstation?
VMWare workstation is software that allows user to run more than one operating system in there system. It provides virtualization to run different applications on many operating systems at a single time. It saves the current configuration of operating system for the user in the form of virtual machines. VMWare allows user to view there application and work with so many different OS without even switching between the OSs.

What are the features provided by VMWare for easy access?
VMWare provides several features to make it easy for the user to access and maintain it. The features are as follows:
• VMWare provides web browser interface
• It provides easy to use wizard to configure the settings
• It provides tools to easily create hosts and maintain it from one place
• It provides easy maintenance of Virtual machines
• It provides easy graphics to configure the VMWare settings for security

What are the features of VMWare Player?
VMWare player is a stand-alone player that comes with the installation of VMWare also. The features that make it more popular are as follows:

• Creation of virtual machines can be done with easy install options. The creation and installation can be done directly to the system.
• VMWare Player can run any virtual machine and it can be used by anyone, anywhere. It allows quick and easy access, to take the advantage of security, portability and flexibility to manage the virtual machines.
• VMWare player allows sharing of virtual machines with other computers or users.

What are the different components used in VMWare infrastructure?The different and major components used in VMWare infrastructure is as follows:
1. lowest layer which acts as a ESX server host.
2. The virtual centre server that keep tracks of all the VM related images and
    manage it  from one point.
3. VI client: this allows the client to interact with user's applications that are
      running on  VMWare.
4. Web browser is used to access the virtual machines.
5. License server is used to create a server that provides licensing to the applications
6. Database servers are used to maintain a database. 

What are the benefits of virtualization?
Virtualization is a creation of virtual machines and to manage them from one place. It allows the resources to be shared with large number of network resources. Virtualization is having lots of benefits and they are as follows:
1. It helps in saving lots of cost and allows to easily maintaining it, in less cost.
2. It allows multiple operating systems on one virtualization platform.
3. It removes the dependency of heavy hardware to run the application.
4. It provides consolidating servers that are used for crashing of a server purpose
5. It reduces the amount of space being taken by data centres and company data.

How virtual machine’s concept is different for host and guest systems?

Host system is the system that runs the operating system and over which the virtual platform can be installed. The virtual platform that runs another operating system is called as guest operating system. Host and guest can be connected with each other by using the virtual machines. A host system that runs all together its own operating system is called as virtualization host and the guest operating system will be that, which get installed over that operating system.

What are the different types of extensions used by VMWare?

  .log: is used to keep a log file to maintain a key for VMWare. This file allows user to

            see the problems encountered during any installation or while using VMWare.

 .nvram: is used to store the state of the virtual machine in system’s BIOS.

 .vmdk: is a virtual disk file that is used to store the content of virtual machine.

 .vmsd: stores the information and metadata of the system’s snapshots.

 .vmsn: is used to store the snapshot state. It stores both the running state and the time

                when you have taken it.

 .vmss: stores the suspended state of a virtual machine.

 .vmtm: stores the configuration team data.

 .vmx: store the primary configurations for the new virtual machine.
