Fly By Wire

What is Fly by wire? (Basic)
The Fly by Wire is the design of managing flight control systems of an aircraft by electrical power instead of traditional cables, pulleys, and hydraulic actuators on large aircraft. The system uses electrical 

resistance sensors in a flight stick to signal control inputs desired by the pilot to the control surfaces (ailerons, rudder, elevators, spoilers, etc.) Fly By Wire technology can also be used to control engine power, flaps, and landing gear operation. The goal was to eliminate heavy and often difficult to maintain cables and pulleys that traditionally are used to fly the airplane. There is a belief that Fly By Wire is more accurate and less prone to pilot error.
But Fly By Wire is not an all electrical powered system to control surfaces. The amount of force and power (torque) to control the movement of large control surfaces such as flaps, ailerons, rudder, etc.) is too much for electrical motors to manage. Hydraulic actuators still power most of these systems. The Fly-By-Wire connects and terminates at the hydraulic actuator motors which are often housed in the inner wing bulkheads and near the end of the tail or base of the rudder assembly.
