The memory layouts implemented by various virtual machines may be different, but they can accept a consistent symbol reference because

Considering the hassle of transmitting files between Windows and Linux virtual machines, it is intended to install the Samba server in the virtual machine to share files with Windows. However, the installation of the configuration process twists and turns, the following records:One, the installation of Samba serverThe normal installation process is as follows: 1.

appropriate Virtual Machine version. It should be noted that the release of J2SE 5.0 contains two versions of virtual machines, one Client VM and one Server VM, which are used in different situations.To determine whether a machine is server-level, there is a standard: whether two or more CPUs are available, and whethe

The old generation is a guarantee of the role.3. Mark sorting algorithm. Mark the surviving objects and move them to one end of the memory space, freeing up the memory space outside the end boundary.
