We've come a long way since the invention of Charles Babbage's ‘difference engine’ in 1822 and the period when computers used wires and punch cards for programming purposes. The evolution in the history of computers though began in the early 50’s of the nineteenth century. Since then both computers and programming languages written to work on them have expanded manifolds both due to development of new languages and also due to the slow death of older, outdated ones. Computer languages were first composed only of a series of steps to wire a particular program. These resulted into a series of steps keyed into the computer which were then executed one by one. With time, these languages attained many additional features and capabilities, such as, logical branching and objects orientation and this is how we know these languages today.
