Explanation of Solution

Need of business professional to know about computer software:

The business professional must know about the various software components in order to manage the various resources which are discussed as follows:

Operating System:

Each computer has the operating system that are nothing but the computer programs used for the management of the various computer resources.

• The operating system plays an important role for the function of various system performances such as read operation, write operations and allocation of main memory and to perform the swapping of memory, responding to error and exception handling and to perform the backup, recovery of the resources.
• The operating system is also responsible for managing the various input and output devices such as the display, keyboard and mouse and to control other external devices.

Virtualization:

Virtualization can be defined as the process in which one computer system can appear as many computer systems. It is possible for one operating system that is known as host operating system to run as one or more operating system as the applications.

• The operating system that has been hosted is known as the Virtual machine where more than one operating system can be operated and each virtual machine can have their system resources allocated to it.

Types of virtualization:

There are three types of virtualization which are as follows:

PC virtualization:

• It is the process of virtually installing more than one operating system in a single personal computer.
• The user can be able to install more than one Operating System (OS) using some virtualization software such as VMware and both the OS can share the same system resources.

Server virtualization:

• The server virtualization is the process of hosting more than one server computer into a single server computer.
• The user can virtually host two virtual machines where each machine can act as server computer.

Desktop virtualization:

• The term desktop virtualization is the process of installing many operating systems for desktop in a single server...
