Article Introduction：This article uses Red Hat Linux9 version as an example to explain. The network management of Red Hat Linux 9 version is very comprehensive and network configuration changes can be made in many places. However, it should be noted that in version 9, users can make network configuration changes in the configuration file, but the system will not. Execute the changed command, which is executable in versions prior to version 9. Three types of network connections on VMware virtual machines: bridge mode: connect the network card on the host to the virtual network card Vmnet0 through a virtual hub. In bridge mode, the network cards of the virtual machine are connected to the virtual switch Vmnet0. When the virtual machine wants to access the Internet Is the Linux system easy to use when managing the Linux system and network? It is necessary to configure the virtual machine IP address, subnet segment, network segment, etc. with the host network.

Article Introduction：The Java virtual machine uses reference counting to manage memory usage. When the reference count of an object reaches 0, the JVM will perform garbage collection. The reference counting mechanism includes: each object has a counter that stores the number of references pointing to the object. When the object is created, the reference counter is set to 1. When an object is referenced, the reference counter is incremented. When the reference ends, the reference counter is decremented.

Article Introduction：Virtual machines do little harm to the computer. The reason is that virtual machines generally do not cause direct harm to computers. A virtual machine is a software tool that allows the creation and running of multiple virtual operating system environments on a physical computer. It does this by simulating hardware and resources on the host operating system. If the virtual machine is not properly configured or the resources are allocated unreasonably, , may cause performance degradation or instability on the host computer. In addition, the virtual machine may also occupy more storage space on the host computer. Therefore, when using a virtual machine, it is recommended to properly configure the resources of the virtual machine.
