Charles Babbage is considered the father of computers, having conceived the first automatic digital computer called the Analytical Engine in the 1830s. Computers have evolved through five generations from vacuum tube-based first generation computers in the 1940s-1950s to today's microprocessor-based fourth generation computers. Computers are digital electronic machines that can be programmed to carry out sequences of operations automatically and have numerous benefits like multitasking, accuracy, and speed.
