who created the mouse that is used with computers today
Computer mouse Douglas Engelbart of the Stanford Research Institute (now SRI International) has been credited in published books by Thierry Bardini,[11] Paul Ceruzzi,[12] Howard Rheingold,[13] and several others[14][15][16] as the inventor of the mouse. Engelbart was also recognized as such in various obituary titles after his death in July 2013.[17][18][19][20]
History of personal computers The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1980s. The 1981 launch of the IBM Personal Computer coined both the term Personal Computer and PC. A personal computer is one intended for interactive individual use,[citation needed], as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals. After the development of the microprocessor, individual personal computers were low enough in cost that they eventually became affordable consumer goods. Early personal computers – generally called microcomputers – were sold often in electronic kit form and in limited numbers, and were of interest mostly to hobbyists and technicians.
