A 1958 article in Harvard Business Review referred to information technology as consisting of three basic parts: computational data processing, decision support, and business software. The first basic function a computer can accomplish is storing information, typically in binary form (as either a one or a zero). What is a Computer? The primary purpose of computer system servicing is to provide you with the knowledge and skills that will help you become computer service and repair technicians. The primary function of a computer system is to execute a program, sequence of instructions. An electronic device, operating under the control of instructions stored in its own memory unit, that can accept data (input), manipulate the data according to specified rules (process), produce information (output) from the processing, and store the results for future use.
