History of computer

History of modern computer begins with automated calculation and programmability. The computer was first invented by Charles Babbage in 1822 who is also known as the father of computer. Charles Babbage was the one who invented the concept of a programmable computer in about 1856. Dr. John V. Atanasoff and his assistant Clifford Berry build the first electronic digital computer (Atanasoff Berry Computer) in 1939. But the device was designed to solve the system of linear equation. Later in 1941, Konrad Zuse built the first working computer and in 1955, he built the first computer on the basis of magnetic storage. George Stibitz is internationally recognized as a father of the modern digital computer. While working at Bell Labs in November 1937, Stibitz invented and built a relay-based calculator he dubbed the "Model K" (for "kitchen table"), on which he had assembled it), which was the first to use binary circuits to perform an arithmetic operation. Later models added greater sophistication including complex arithmetic and programmability.
