3. Hypervisor
   A hypervisor (or virtual machine monitor, VMM, virtualizer) is computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine, and each virtual machine is called a guest machine.

4. Types of Virtualization
   There are 7 primary types of virtualization, and each one differs according to the element it is used on. Each type can also have a different effect on network security. There are OS Virtualization—aka Virtual Machines, Application-Server Virtualization, Application Virtualization, Administrative Virtualization, Network Virtualization, Hardware Virtualization, Storage Virtualization

5. User operating system interface
   A User interface (UI) facilitates communication between an application and its user by acting as an intermediary between them. The two basic function of a user interface of an application is to take the inputs from the user and to provide the output to the users. A user interface of any operating system can be classified into one of the following types: Graphical user interface (GUI) and Command line user interface (CLI)

6. System Programs in Operating System
   System Programming can be defined as act of building Systems Software using System Programming Languages. According to Computer Hierarchy, one which comes at last is Hardware. Then it is Operating System, System Programs, and finally Application Programs. Program Development and Execution can be done conveniently in System Programs. Some of System Programs are simply user interfaces, others are complex. It traditionally lies between user interface and system calls.

7. System call in Operating System
   A system call is a mechanism that provides the interface between a process and the operating system. It is a programmatic method in which a computer program requests a service from the kernel of the OS. There are 5 different categories of system calls: process control, file manipulation, device manipulation, information maintenance, and communication.

8. Process Control
   This system calls perform the task of process creation, process termination, etc.

9. Cloud Computing
   Cloud computing is the delivery of on-demand computing services from applications to storage and processing power typically over the internet and on a pay-as-you-go basis.
