This is the essence of programmability
7、.First general-purpose computersDuring the first half of the 20th century, many scientific computing needs were met by increasingly sophisticated analog computers, which used a direct mechanical or electrical model of the problem as a basis for computation. However, these were not programmable and g

Of his role in the creation of the modern computer, Time magazine in naming Turing one of the 100 most influential people of the 20th century, states: The fact remains that everyone who taps at a keyboard, opening a spreadsheet or a word-processing program, is working

The use of digital electronics (largely invented by Claude Shannon in 1937) and more flexible programmability were vitally important steps, but def

In 1998 the Z3 was proved to be Turing complete, therefore being the worlds first operational computer.The non-programmable AtanasoffBerry Computer (commenced in 1937, completed in 1941) which used vacuum tube based computation, binary numbers, and regenerative capacitor memory. The use of regene

In the 1970s, integrated circuit technology and the subsequent creation of microprocessors, such as the Intel 4004, further decreased size and cost an

By the late 1970s, many products such as video recorders contained dedicated computers called microcontrollers, and they started to appear as a replacement to mechanical controls in domestic appliances such as washing machines.
