Just think of your computer or server as a huge building with thousands of doors. Most are closed, but you purposely open a few to allow traffic in and/or out of. Those that are open are only open for a specific purpose and will only lead in or out of a specific place in the building.
When working on an office, it’s great and all that you have “the power of accurate observation” but god our Debbie downer is insufferable.
