Who developed the Difference Engine and Analytical Engine two punched-card controlled general purpose calculators?
The Difference Engine and Analytical Engine were developed by the British mathematician and inventor Charles Babbage. The Difference Engine, designed to compute polynomial functions, was conceived in the early 1820s, while the more advanced Analytical Engine, which featured concepts of programmability and data storage, was designed in the 1830s. Although neither machine was completed during Babbage's lifetime, his ideas laid the groundwork for modern computing.

What is the difference between dependent and controlled variables?
The controlled variable is the one that you chose to change while the dependant is the variable that changes because it is effected by the controlled variable
What is the difference between manipulated variables and controlled variables?
They are the same. These are names for the variables in an experiment that are controlled by the experimenter, as opposed to the output variables, the results you collect at the end of the experiment Hope this helped!
What is the difference between an experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What is the difference between the controlled variable and an independent variable?
A controlled variable is one which you try to keep constant. The independent variable is the on that you change. The dependent variable is the one you measure. For instance, how much will a drink cool down in one minute when you add a certain number of ice cubes to it? The independent variable is the number of ice cubes. The dependent variable is the temperature drop. There are many possible controlled variables: the starting temp of the drink, the size of the ice cubes, the type of glass, the air temperature, and so on. See related link below.
Why must a controlled experiment have one manipulated variable?
a controlled experiment must have only one manipulated variable becuase if the experiment had multiple manipulated variables then it would not be a controlled experiment anymore it would be a manipulated Deseret experiment
What is the difference between a controlled experiment and a controlled group?
a controlled group is like an idea but an experiment that is controlled cannot be changed.
Two groups of students were tested to compare thir speed working math problems Each group was given the same problems.One group used calculators and the other group computed without calculators?
The independent variable in this study is the use of calculators, while the dependent variable is the speed of solving math problems. By comparing the two groups, researchers can determine if the use of calculators has an impact on the speed of problem-solving. To analyze the results, statistical tests such as a t-test or ANOVA can be used to determine if there is a significant difference in speed between the two groups.
What is the difference between a remote controlled helicopter and a remote controlled drone?
A remote controlled helicopter is different from a remote controlled drone in that a drone is any unmanned aerial vehicle.
What the difference between a variable and control?
The difference between a controlled variable and a variable is in their state. A controlled variable is something which is rigid and constant while a variable is liable to change and inconsistent.
What is the difFerence between nc and cnc?
NC is numerically controlled (hard wired) and CNC is computer numerically controlled.
Why is a controlled variable important in a controlled experiment?
because knowing what is the difference between objects and produres and data is important
What is the difference between dependent and controlled variables?
The controlled variable is the one that you chose to change while the dependant is the variable that changes because it is effected by the controlled variable
What is the difference between control and controlled variable?
control is when nothing is done to the experiment and controlled variable is that you have control over the experiment.

What is the difference between a driving and driven dimension?
Driving Dimension: the geometry is controlled by the dimension. Driven Dimension: the dimension is controlled by the geometry.
What is the difference between mosfet and photo diode?
the current in mosfet is controlled by electric field where as in poto diode is controlled by intensity of light
What is the Difference between voltage controlled device and current controlled device?
The difference between a current control device and voltage controlled device is that for current controlled device, the current is constant and the voltage is variable while for a voltage controlled device, the voltage is constant and the current is variable.
