A Presentation On: Virtual Systems: By: Samprit Patel Madhuri Shinde

Virtual systems allow users to run separate operating systems within virtual machines on a single computer. Each virtual machine has its own virtual CPU, memory, disk, and other hardware that is mapped to the actual computer hardware. This allows users to test software in different environments, try new operating systems safely, quickly set up office systems, and back up systems. However, virtual machines also use the same physical resources as the host computer, so running multiple virtual machines can slow down older or lower-spec computers that do not have sufficient memory or processing power.

Introduction

In software reviews, often a program is tested in a platform virtual


machine. If you are a programmer, you may use virtual machines to see if your
product runs safely in another operating system—for example, the different
versions of windows. Maybe you like to test and analyze malware, and don't
want to get your computer infected. This virtualization can help.
What is VIRTUAL SYSTEM?

A virtual machine is a type of computer application used to create a virtual


environment, which is referred to as virtualization.

Virtualization : Virtualization is defined as a logical view


between computer hardware systems and the software used to operate them.

How do Virtual System Works?

VMWare hosts each guest operating system in a separate, secure virtual


machine. Each virtual machine (VM) has its own virtual CPU, memory, disk,
etc. and all of the virtual hardware is mapped to your computer's real hardware.
Each virtual machine also comes complete with its own BIOS that can be
edited the same way you'd edit the real BIOS on the computer that VMWare is
running on. This lets you customize your virtual machines and control all of
the usual stuff that you can control via your PC's actual BIOS.
Example of A Virtual System.

JAVA VIRTUAL MACHINE

Backup your system


Advantages

Mobility

File-sharing capabilities

Storage
Scope Of Improvement

If you are thinking this is going to eliminate the need for a better computer to run
more programs at the same time, etc.— I'm afraid you need to think again. Virtual
machines use the same memory, the same CPU, and same hard drive as your real,
host computer. This can be quite a problem, especially for computers with low specs.

For example: On my laptop, I have 2GB of memory. Usually, that is quite enough to
satisfy me, as often I only use about 50-55% of it. However, running two operating
systems, one on a virtual machine, can increase that to 90+%. With that amount of
RAM used, memory swapping might occur, and that slows things down.

So just remember: If you don't have a new, high-end computer, virtual machines can
make things a bit slower. For me, most of the time running one is something of an
ordeal, because I have to shut down mostly unnecessary processes and services.
Conclusion

A virtual machine has many uses—security, trialing, studying. But it also


sucks up system resources, so it isn't an easy thing for some.
