when was the first laptop invented and by whom
Laptop As 8-bit CPU machines became widely accepted, the number of portables increased rapidly. The first laptop-sized notebook computer was the Epson HX-20,[9][10] invented (patented) by Suwa Seikosha's Yukio Yokozawa in July 1980,[11] introduced at the COMDEX computer show in Las Vegas by Japanese company Seiko Epson in 1981,[12][10] and widely released in 1982.[10][13] It had an LCD screen, a rechargeable battery, and a calculator-size printer, in a 1.6 kg (3.5 lb) chassis, the size of an A4 notebook.[10] It was described as a "laptop" and "notebook" computer in its patent.[11]
Charles Babbage Considered by some to be a "father of the computer",[2][3][4][5] Babbage is credited with inventing the first mechanical computer that eventually led to more complex electronic designs, though all the essential ideas of modern computers are to be found in Babbage's analytical engine.[2][6] His varied work in other fields has led him to be described as "pre-eminent" among the many polymaths of his century.[1]
