While many others do because of them.
Came back from lunch to discover we didnt have net access (nooooo! 
) so went back into the canteen. Upon returning I see one of the other guys on his knees looking at the switch on the floor (note: dont call them hubs, Flash might kill me while saving the universe 😛 ) only to discover that the uplink cable had worked its way loose during the morning.
It falls back to a saying from the start of the course, “50% of all problems are cable related” 🙂
Im dreading it when we start working on Subnet Masks and how to calculate them, i sense my impending doom! (either that or Flash is off to fight Ming)
