The approaches differ in where they draw the boundary. Namespaces use the same kernel but restrict visibility. Seccomp uses the same kernel but restricts the allowed syscall set. Projects like gVisor use a completely separate user-space kernel and make minimal host syscalls. MicroVMs provide a dedicated guest kernel and a hardware-enforced boundary. Finally, WebAssembly provides no kernel access at all, relying instead on explicit capability imports. Each step is a qualitatively different boundary, not just a stronger version of the same thing.
Windows 的资源管理器是一个有边界的、强调秩序的内容呈现窗口。在窗口内，所有内容均强制按照某种特定的顺序（如名称、日期、类型）排列，并严格对齐网格。资源管理器仅有一个例外，那就是桌面。只有在桌面上同时取消「自动排列图标」和「将图标与网格对齐」后，图标才可以像画布一样自由放置。，推荐阅读旺商聊官方下载获取更多信息
