正确说法

• 这个项目之所以能够绕过正常的审批流程顺利推进，外界一直怀疑背后有权贵充当后台，但始终没有找到确凿的证据。(The reason this project was able to bypass normal approval procedures and proceed smoothly has long aroused suspicion that powerful figures were acting as behind-the-scenes backers, though no conclusive evidence has ever been found.)
• 系统后台显示，当天峰值时段共有超过两百万名用户同时在线，服务器承受了极大的并发压力。(The system backend shows that during the peak period that day, more than two million users were online simultaneously, placing enormous concurrent load on the servers.)

错误说法

• 后台 exclusively in the computing sense without context — the word has strong figurative meanings in Chinese that readers may default to; always provide clear context when referring to a software backend to avoid ambiguity
