 OSI MODEL AND ITS LAYERS OSI stands for Open System Interconnection Model which was developed by ISO which stands International Organization of Standardization in 1984. This model has seven layers which have their individual roles which serve whole as interconnection model. It has layer from the physical layer from bits to the higher level data representation over a  distributed  application.                        OSI model has seven levels which are as follows  :- Application layer. Presentation layer. Session layer. Transport layer. Network layer. Data layer. Physical layer.  Following are the defining of the OSI layer:- 1 . Physical Layer   :- It is the lowest layer of OSI layer .The main work of this layer is to establish the  physical connection of the devices .It transmit the data  in form of bits , from one   node to the next in the 1's and 0's . It send the data...

VIRTUALIZATION Virtualization is the way through which you can create many environments by which you can run different operating systems on one platform. It is the layer which is abstracted from the systems that uses System hardware more efficiently . In Virtualization it is seems to us that the virtual machine we are working on our host operating systems , is the dedicated machine. A computer machine has basically three major and huge terms which are more significant are listed  below: Computation. Storage. Network. People uses Virtualization for many purposes. Many people uses it to run application programs which is meant to that operating systems(on which they are not working ) without being reboot from the host operating systems . Virtualization is achieved through Hypervisor which are also of two types , usage of them are depending on the conditions which are listed down below: Types of Hypervisor : Type-1 and Type-2. Type-1 Hypervisor are used in case of your Bare metal(B...
