The history of computing hardware spans the developments from early devices used for simple calculations to today's complex computers, encompassing advancements in both analog and digital technology. The first aids to computation were purely mechanical devices which required the operator to set up the initial values of an elementary arithmetic ...
The history of computing hardware starting at 1960 is marked by the conversion from vacuum tube to solid-state devices such as transistors and then integrated circuit (IC) chips. Around 1953 to 1959, discrete transistors started being considered sufficiently reliable and economical that they made further vacuum tube computers uncompetitive .
Benjamin felt that a more elegant input device was needed and invented a ball tracker [69] [70] system called the roller ball [69] for this purpose in 1946. [69] [70] The device was patented in 1947, [69] but only a prototype was ever built [70] and the device was kept as a secret outside military. [70] 1947 September United Kingdom
German scientist Otto von Guericke invented a device that creates static electricity. This is the first ever electric generator. 1705: English scientist Francis Hauksbee made a glass ball that glowed when spun and rubbed with the hand 1720
In 1993, Ashok Gadgil invented a lightweight, easy-to-use and economical device that used UV light to purify water. It could process four gallons per minute at a cost of 5 cents for every thousand ...
Computer hardware includes the physical parts of a computer, such as the central processing unit (CPU), random access memory (RAM), motherboard, computer data storage, graphics card, sound card, and computer case. It includes external devices such as a monitor, mouse, keyboard, and speakers. [1] [2]
Invented the concept of a hardware abstraction layer called the BIOS, with both conceptually laying the foundation to all DOS-based operating systems on personal computers. Worked on diskette track buffering schemes, read-ahead algorithms, virtual disk drives, and file system caching.
Timeline of computing presents events in the history of computing organized by year and grouped into six topic areas: predictions and concepts, first use and inventions, hardware systems and processors, operating systems, programming languages, and new application areas.
