A computer is a digital electronic machine that can be programmed to carry out arithmetic and logical operations automatically. It takes in data through input devices, stores the data and any instructions in its memory, processes the data using the central processing unit, outputs the results through devices like monitors or speakers, and is managed and controlled overall by software that directs its functions. A computer consists of both hardware, the physical parts like processors, memory, and input/output components, as well as software which provides the instructions for what tasks to perform and how.
