But its a centralized computer system. It seems like you can basically gather all the information you need from the same computer terminals. Also lots of stuff being maintained is no doubt better accessed in places like main engineering. I do like the idea of each bridge officer having like a headset in which they stay in touch with lower deck personal. If the security officer is seeing a glitch in the phasers he just call down to engineering to run a test on the system and if it's a problem then alert the captain.
