??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

VMware Player automatically detects the type of system in the original system image, enabling a set of so-called "Easy Install" systems to automatically install the system for you, or even install the system automatically without asking how to partition it. This is not friendly to the system encapsulation we need to highly customize, so it is highly recommended to select "I will install the operating system later".3. Select the type of operating system
