What language do they build other languages with?

Question

What language is used to build low level languages like c++ and java?

How could you build the first language with no language?

Answer 1

There is no such thing as "no language". The central processing unit operates on a series of signals to which we refer as bits or ones and zeroes (technically, changes in the electrical current flow). In th 50s, coding was done directly in what the CPU could "understand" and the pace at which programming was done was up to around 20 assembler commands per day.
