A more interactive form of computer use developed commercially by the middle 1960s. In a time-sharing system, multiple teleprinter and display terminals let many people share the use of one mainframe computer processor, with the operating system assigning time slices to each user's jobs. This was common in business applications and in science ...
Konrad Zuse was born in Berlin on 22 June 1910. [21] In 1912, his family moved to East Prussian Braunsberg (now Braniewo in Poland), where his father was a postal clerk.Zuse attended the Collegium Hosianum in Braunsberg, and in 1923, the family moved to Hoyerswerda, where he passed his Abitur in 1928, qualifying him to enter university.
Among the groups reporting to Shugart was the team that invented the floppy disk. Shugart joined Memorex in 1969 as Vice President of its Equipment Division and led the development of its 3660 (compatible with IBM 2314) and 3670 (compatible with IBM 3330) disk storage subsystems. His team also developed the Memorex 650, one of the first ...

The Lisa was one of the first personal computers with a graphical user interface (GUI) that was sold commercially. It ran on the Motorola 68000 CPU and used both dual floppy disk drives and a 5 MB hard drive for storage. The machine also had 1MB of RAM used for running software from disk without rereading the disk persistently. [72]
The first modern analog computer was a tide-predicting machine, invented by Sir William Thomson, later Lord Kelvin, in 1872. It used a system of pulleys and wires to automatically calculate predicted tide levels for a set period at a particular location and was of great utility to navigation in shallow waters.
