What is a Computer?

  • A computer is a programmable electronic device that accepts raw data as input and processes it with a set of instructions (a program) to produce the result as output.

  • It not only processes both numerical and non-numerical calculations but also saves the output for future reference.

  • The term "computer" originates from the Latin word "computare," meaning to calculate.

  • The Analytical Engine, invented by Charles Babbage in 1837, was the first computer, utilizing punch cards as read-only memory.
