Compose a 1250 words assignment on history and impact of computing. Needs to be plagiarism free! The popularity of computers as a household item surged in the early 1980s after the emergence of Microsoft and Apple operating systems that blended text and graphics substituting the text-only system common in the 1970s (Black, 2001).
In the 1930s, the processors used vacuum tubes and relays, which could be utilized as switches. Some computers of this time had differential analyzers that utilized mechanical internals but applied electric motors to drive or power them. It is significant to note that the computers of the 1930s were either digital or an analog such as the intricate number calculator and Model K. It was also during this time that the first access remote computing was developed. This system required a person to take problems presented by the audience and then insert these problems on the computers’ keypad of the teleprinter that outputted the feedback afterward. The computing and technological ideas developed during this time are still applied today. For instance, the Z3 applied for floating-point numbers in calculations and was the first programmed digital processor or computer to be developed.
During the Second World War, the first electronic computer was created. The earliest one was the colossus that was created to decrypt or intercept German secret codes during the war. It utilized paper tape and vacuum tubes and could do several Boolean logical operations. Some of the 1940 electronic computers such as the Harvard Mark 1 and ENIAC utilized the decimal numerical system while others such as Colossus Mark 2 utilized binary systems (Black, 2001).

Early computers focused on mathematical, defense, and scientific capabilities, the computers that were developed in the 1950s were designed for business operations such as accounting and banking. During this time, transistors were developed to substitute the vacuum tubes, which led to the manufacturing of small computers. .
