The Digital Computer focuses on the principles, methodologies, and applications of the digital computer. The publication takes a look at the basic concepts involved in using a digital computer, simple autocode examples, and examples of working advanced design programs. Discussions focus on transformer design synthesis program, machine design analysis program, solution of standard quadratic equations, harmonic analysis, elementary wage calculation, and scientific calculations. The manuscript then examines commercial and automatic programming, how computers work, and the components of a computer installation. Topics include central processor, input and output peripheral devices, peripheral storage devices, basic computer elements and operations, basic process of computer operations, automatic programming facilities, working of automatic programs, and solution of quadratic equations. The text takes a look at the use of computers by small organizations, responsibilities of a central computer service, computer approach philosophy, and computer acceptance. The manuscript is a vital source of data for computer science experts and researchers interested in the digital computer.
