History of electronic engineering capable of performing the same tasks that any other computer can perform. Therefore, computers ranging from a netbook to a supercomputer are all able to perform the same computational tasks, given enough time and storage capacity. In 1969, Ted Hoff conceived the commercial microprocessor at Intel and thus ignited the development of the personal computer. Hoff's invention was part of an order by a Japanese company for a desktop programmable electronic calculator, which Hoff wanted to build as cheaply as possible. The first realization of the microprocessor was the Intel 4004, a 4-bit processor, in 1969, but only in 1973
