<h3>What is a virtual machine?</h3>
- A virtual machine is the virtualization or emulation of a computer system in computing.
- The functionality of a physical computer is provided by virtual machines, which are built on computer architectures.
- Their use may necessitate specialized hardware, software, or a combination of both.
- Virtual machines' primary function is the simultaneous operation of several operating systems on a single piece of hardware.
- Without virtualization, running two different physical units would be necessary to run different operating systems, such as Windows and Linux.
- Through the use of virtualization technologies, virtual machines are made possible.
- Multiple virtual machines (VMs) can run on a single machine thanks to virtualization, which simulates virtual hardware using software.
- The real machine is referred to as the host, and any virtual machines running on it as the guests.

a. A constructor must have the same name as that of a class. For example
public class MyFirstClass{ // this is the class name

b. Constructors never have a return type not even void because it is only used to initialize the values of data members of the class when the object of the class is created so constructors are not directly called hence they do not need to have a return type.
c. Constructors are invoked using the new operator.
When the new object is created the constructor is invoked in order to initialize the variables of a class. The memory is allocated to the object and then the constructive is invoked for the purpose to initialize the object.

All requests for a website in a web server is done in a web browser in a client device. For a website to be easy searched for , the search engine optimisation technique is used.
A hosted website on a server must have a unique and usable domain name and the page loading on a browser should be made faster by optimising the size of the scripting language.
