VPC

VPC-Virtual PC
There are two different types of VPCs, these are system virtual machine and process virtual machine. The system virtual machine, which is the one that i have installed, can also be called a hardware virtual machine. This virtual machine allows the sharing of physical machine resources between the virtual machines. Each of the machines run their own operating system. Some advantages of using a virtual machine are:

• More than one OS can co-exist on the same computer.
• The virtual machine can provide an instruction set architecture (ISA) that is different from the one on the main computer/OS.
• It has high avaliablility and disaster recovery.

One main disadvantage of a virtual machine is that it is less efficient as it accesses the hardware indirectly. One other disadvantage with running virtual machines on your computer is that it could slow down the computer as it takes up too much of the memory. This could occur if you gave the virtual machine more memory or if the memory on your computer is small. If the computer has a small memory, installing and running a virtual machine would mean that it would take up a lot of the memory and slow down both the virtual machine and the main computer/OS.
