in which country the first computer made
Answers
First programmable computer. The Z1 was created by German Konrad Zuse in his parents' living room between 1936 and 1938. It is considered to be the first electromechanical binary programmable computer, and the first really functional modern computer

It depends on how you want to define computer. I am limiting this discussion to digital computers, and ignoring analog ones, which are a completely different beast.
England, 1837. Charles Babbagedescribes the plans for his Analytical Engine, a mechanical digital computer using punched cards as input which was only partially constructed. It included sequential control, branching and looping, and would have been Turing-complete. In 1843, Ada Lovelace developed an algorithm that would have enabled the Engine to calculate a sequence of Bernoulli numbers, and is thus considered by some to be the world’s first computer programmer.
England, 1936. 99 years later, the principle of the modern computer is first described by computer scientist Alan Turing in his seminal paper, On Computable Numbers. However because of his work in World War II breaking German codes, he won’t be involved in the actual design of an electronic computer until the Pilot-ACEproject (1950).
Germany, 1941. Konrad Zusecompletes the Z3, the world's first working electromechanical programmable digital computer. It included about 2000 relays, did 22-bit floating point arithmetic and was considered marginally Turing complete (it had looping but not conditional branching). The German Aircraft Research Institute used it to perform statistical analyses of wing flutter. The original Z3 was destroyed on 21 December 1943 during an Allied bombardment of Berlin.
