The Z1 by Konrad Zues

The Z1 was created by a German man named Konrad Zues in 1936 to 1938. Konrad’s Z1 was created in his parent’s living room. The Z1 ran on electricity and was more like a calculator than a computer. Unfortunately his computer was not reliable to work every time.

The EDSAC was an early British computer that was thought to be inspired by John Von Neumans. Although the EDSAC was made by Maurice Wilkes, he had help from the students at Univeristy of Cambrige Mathmatical Laboratory. The name EDSAC stands for Electronic Delay Storage Automatic Calculator. The EDSAC was the second operational computer.

The Analytical Engine contained Arithmetic Logic Unit (ALU) which is a basic flow with a memory. As mentioned before Charles Babbage could not finish his computer due to funding purposes.
