??This phrase feels like the nature of the GC .??????1. Procedure Counter (program Counter Register)??A program counter is a small amount of memory space that acts as a line number indicator of the bytecode that is being executed by the current thread . The bytecode interpreter works by changing the value of this counter to select the next byte-code instruction to execute, and the basic functions such as branching, looping, jumping, exception handling, thread recovery, and so on, need to rely on

My current practice is to install linux (centos) in vituralbox and run it in the background (to minimize installation, only command line ). Build a LAN between my host and the virtual host, and then deploy my website on linux, finally, enter the IP address of the VM in the browser of the host to access the website. In this way, not only can the host access the site, but other virtual machines
