Unit I: Introduction to Computer | BCA 1st Semester Computer Fundamentals and Application Notes Pdf

The word "computer" is derived from the Greek word "compute" which means "to calculate". A computer is an electronic device that can be reprogrammed to take input from the user, process them by using CPU "Central Processing Unit" and give output in the human-readable and understandable form and even store the output for future use.

It can process both numerical and non-numerical (arithmetic and logical) calculations. The only language supported by the computer systems is "Binary System" or "Machine Language". The Machine Language is represented by 0's and 1's.
