What is the difference between a fly-by-wire system compared to hydraulic systems?

Well, both of them are related. Large jet liners require hydraulic power to operate the huge flight controls such as ailerons, elevators and rudders. In a conventional aircraft, mechanical linkages attached to the control wheel and rudder pedals are used to operate hydraulic control valves that in turn provide hydraulic fluid to hydraulic actuators that in turn move those heavy flight control surfaces. In a Fly By Wire aircraft, an electrical signal is generated when the same control wheel and rudder pedals are moved which in turn electrically opens or closes the same hydraulic control valves that provide hydraulic pressure to the hydraulic actuators. To summerize, hydraulic power is required in both Fly Bt Wire aircrafts and conventional aircrafts.

Difference between hydraulic fluid and hydraulic oil?
There is no difference that I am aware of. These terms seem to be used interchangably.
What is the difference between an infiltration rate and a hydraulic conductivity?
It seems that infiltration rate is a soil parameter which is determined in the field with all soil aspects. However, hydraulic conductivity is determined in the lab and it is not typically illustrated soil permiability as compared with infiltration rate
What is the difference between hydraulic and hydrostatic?
hydraulics uses the principle of hydrostatic pressure to work
Difference between hydraulics and pneumatics?
hydraulic is liquid based, pneumatic is air.
What is the difference between hydraulic motors and pumps?
A hydraulic pump uses an external mechanical force to pressurize the hydraulic fluid. A hydraulic motor uses the pressurized hydraulic fluid to apply a mechanical force an external machine. See the difference between a pump and a motor.

Main difference between hydraulic and lubricating oil?
engine oil is thick than hydraulic oil
What is the difference between hydraulic action and abrasion?
By: Gwen The difference between abrasion and hydraulic action is that: In "Hydraulic action" the water flows so fast that it is forced to crack the bank BUT For in "Abrasion" the river bed is broken/cracked because of the rock and stones in the river.
What are the properties difference between Refrigeration and hydraulic oils?
Hydraulic oils are substances that are hot, while refrigeration properties are cold.
What is difference between hydraulic oils and slide way lubricant?
hydraulic fluid is used internally only,slide way lubricants are external
What is the difference between hydraulic and hydrostatic?
hydraulics uses the principle of hydrostatic pressure to work
Is there a difference between intake and exhaust hydraulic valve lifters?
No the lifters themselves are all the same. I recommend lightweight pushrods though if you can get them and stay with hydraulic.
How the correlation between hydraulic motor and hydraulic pump?
Internally, they're pretty much the same. The difference is the operation expected of it - a hydraulic pump converts mechanical energy to fluid energy, whereas a hydraulic motor converts hydraulic energy to mechanical energy.
What is the difference between HD-46 and HD-68 Hydraulic oil?
Basically, the only difference between HD-46 and HD-68 hydraulic oils is the weight of the product. HD-46 is a 15 weight oil, but HD-68 is a 20 weight oil.
What are the similarities between Morocco and the US?
The difference between the USA and Morocco cannot be compared.
What is the difference between solid and hydraulic motor mounts?
A solid mount has no play where as a hydraulic is flexible so you do not feel the torque of the motor(what you would want for daily driver in my opinion).
