Say you have two physical computer at home and you want to share the same keyboad and mouse across the two computers, this is what Synergy allows you to do.
In a typical situation if you have two computers (and assuming you want to do GUI tasks) you will have to have two of the basic peripherals, that is a mouse, keyboard and monitor. But now we want to get rid of one mouse and keyboard so that all we are left with is two computers, two monitors and one mouse and one keyboard used on both computers and this is Synergy attemps to do.
If you have a flash disk plugged on computer A it will be accessed when you are on computer A and all that devices that are on computer B can be accessed when you are on computer B. The only resource shared is the mouse and the keyboard.
