The connection for the video monitor has bolts that screw into the computer back panel to keep it in place. The power cord is large enough and tight enough that it doesn't come out easily. The phone cables that connect to the modem have a spring tab that holds them in place.
But the cords for the mouse and keyboard! They are small and fit fairly loosely. Why is that? And the keyboard and mouse are the computer components that I actually move the most. And what if I vacuum behind the computer? Everytime I run the ShopVac I have to be careful not to bump the cables! But what if they're dusty? Should I have to disconnect them to clean them? Isn't there some way these cables can be more securely connected?

As an IT guy, do you realise how annoying those connectors are?! ;)
just hang in a slot
I assume you mean they're USB. Once the connectors are used a lot, I see this a lot with memory sticks, they become a little loose.
Get a pair of pliers and gently, and very carefully slightly squash the connector so it bows a tiny bit in the middle. That will grip the socket more tightly. But be really careful not to do it too hard or the plug just won't fit any more!
Is this an off the shelf (Dell etc) pc or a do it yourself?
I'm with BeeDeeDubbleU on this. When we first started, everything was SCSI and had to be hooked up in a certain order or you had conflicts. Every time you wanted to add a peripheral you had to shut everything down and make sure it was all hooked up correctly. USB and Firewire are much better solutions.

It's a Dell. To be more specific, what happens is this: under normal conditions, everything's fine. But if I have to reach behind the computer for any reason (like to pick up something that fell behind the desk, to vacuum, etc.) I have to be very careful not to touch any of the USB cables (printer, mouse, keyboard) or they will fall out.
