[Star-Trek,Wars,Gate] How is it that seemingly 99% of battle damage to ships can be repaired from the inside of the ship?

It seems along my travels that when a ship I'm on takes damage that knocks out the engines, weapons, shields, or similarly critical components, that all that is required is to reconfigure a console, swap a few crystals, and enter a few commands. How is it that there is never any external damage preventing a component from going online that would require a crewman to go EVA?

Starships inherently have a lot of risks because of what they're doing and where they fly. Because of this, ships generally have quite a few redundancies built in. Usually if, say, the shields were to get knocked out, it likely wouldn't be because the shield generator actually got destroyed, but because the main power connection from the reactor to the shield generator was broken. Usually there is a backup power line or two, and the captain/bridge crew should be able to easily reroute the power through the secondary line. Secondaries usually can't carry as much as the main line and the shield or such won't operate at full capacity, but it's much better than not having shields or engines at all.
