group, by default, these different broadcast domains are isolated from each other. To communicate between different broadcast domains, you need to pass one or more routers. Such a broadcast domain is called a VLAN.What is a VLAN?Virtual LAN; LAN is the range of nodes that the broadcast frame can reach, that is, the scope of direct communication;How VLANs are divided:Based on MAC addressSwitch Port-based implementationBased on IP address implementationBased on user implementationType of Switch i

host directly to execute, This greatly improves the speed of execution.In order for this virtualization technology to work correctly, the constructed virtual machine must process some of these privileged instructions, produce a trap when executed, and pass it on to the lower VMM execution. This is because the unmodified operating system running in the virtual machine takes advantage of the privileged instr
