Who is known as the professor of Mathematics at the University of Cambridge and developed the Difference Engine?
Charles Babbage
What were the four components of the Analytical Engine developed by Charles Babbage?
store(memory), mill (computation unit), input section (punched card reader), output section (punched and printed output)
What has characterised the evolution of computers according to the text?
increasing processor speed, decreasing component size, increasing memory size, and increasing I/O capacity and speed
What were the key characteristics of the evolution of computers according to the text?
Increasing processor speed, decreasing component size, increasing memory size, and increasing I/O capacity and speed

Who was the German mathematician known for inventing a mechanical device capable of addition, subtraction, multiplication, and division?
Gottfried Wilhelm von Leibniz
What were the capabilities of Blaise Pascal's working calculator, the Pascaline?
It could perform addition, subtraction, multiplication, and division via multiple additions and subtraction
What was the role of Ada Lovelace in the development of the Analytical Engine?
She was hired to write programs for the punched cards for the Analytical Engine, making her the first programmer.
What characterized the first generation of computers, and what technology was used as on/off switches?
The first generation of computers used vacuum tubes as on/off switches, allowing them to perform digital computations in binary form.
Who conceived and designed the Electronic Numerical Integrator and Computer (ENIAC)?
John Mauchly and J. Presper Eckert, from the University of Pennsylvania, conceived and designed the ENIAC.
What was the function of the relay controller in the relay computers of the 1930s?
The relay controller worked by turning on and off magnetic coils under logic control, allowing the computer to send simple commands to activate switches.
What were the key features of the Analytical Engine developed by Charles Babbage?
The Analytical Engine had 1000 words of 50 decimal digits each for variables or results, and it could accept values from the store to add, subtract, multiply, or divide them before returning the result to the store. It also could read instructions from punched cards and had instructions for various operations such as fetching values, adding them, and conditionally branching based on the number's positivity or negativity.
Test your knowledge about the key points in the evolution of computers, including increasing processor speed, decreasing component size, increasing memory size, and I/O capacity and speed. Learn about the factors contributing to processor speed and the organization of processors.
