By: Dela Cruz, Mark Darren V. BSCS 1A The History of Computers Before we start! What is a Computer? What is a Computer? A computer is an electronic machine that collects information, stores it, processes it according to user instructions, and then returns the result. A computer is a programmable electronic device that performs arithmetic and logical operations automatically using a set of instructions provided by the user. Who is the Father of the First Computer? Charles Babbage (1791–1871) was an English polymath, known for his contributions to mathematics, engineering, and computer science. He is often considered the “father of the computer.” Babbage originated the concept of a digital programmable computer and is credited with inventing the first mechanical computer, the Difference Engine. Although he didn’t complete many of his designs, his Analytical Engine laid the groundwork for modern computers. His legacy lives on, and parts of his incomplete mechanisms are on display at the Science Museum in London The Difference Engine The difference engine is an automatic mechanical calculator designed to tabulate polynomial functions. It was designed in the 1820s, and was first created by Charles Babbage. The name difference engine is derived from the method of divided differences, a way to interpolate or tabulate functions by using a small set of polynomial co-efficients. Some of the most common mathematical functions used in engineering, science and navigation are built from logarithmic and trigonometric functions, which can be approximated by polynomials, so a difference engine can compute many useful tables. The Analytical Engine The analytical engine was a proposed digital mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage.It was first described in 1837 as the successor to Babbage's difference engine, which was a design for a simpler mechanical calculator. The Father of the Modern Computer Konrad Ernst Otto Zuse was a German civil engineer, pioneering computer scientist, inventor and businessman. His greatest achievement was the world's first programmable computer the functional program-controlled Turing-complete Z3 became operational in May 1941. Thanks to this machine and its predecessors, Zuse is regarded by some as the inventor and father of the modern computer. The world's first working programmable,fully automatic digital computer. The Z3 was a German electromechanical computer designed by Konrad Zuse in 1938, and completed in 1941. It was the world's first working programmable, fully automatic digital computer.The Z3 was built with 2,600 relays, implementing a 22-bit word length that operated at a clock frequency of about 5–10 Hz. Program code was stored on punched film. Initial values were entered manually. Thank You!! May the force be with you.
