Mark - 1 was probably the last electro mechanical computer which was invented by Prof. Howard Aiken in the U.S.A. Mark-1 was constructed in 1943. The main advantage of the Mark I was that it was fully automatic?it did not need any human intervention once it started. It was the first fully automatic computer to be completed. It was also more reliable than the early electronic computers. This machine was capable to multiply two 10- digit numbers in 5 seconds. It was the first machine, which could perform according to pre-programming. It was also known as ASCC (Automatic Sequence Controlled Computer). Mark-1 is considered to be' the beginning of the era of the modern computer' and 'the real dawn of the computer age'.
