A computer is an  electronic device, operating heavily influenced by guidelines put away in its own memory that can acknowledge information (input), measure the information as per specified rules, produce information (output), and store the  information for future use or we can define a computer as a programmable electronic device that accepts raw data as input and processes it with a set of instructions known as programs to produce the results as output. It produces the output after performing logical and mathematical operations and this output can be saved for future use. A computer can process both numerical and non-numerical calculations.
