Digital refers to data represented by numbers, such as 1s and 0s. Digital revolution is based on digital electronics and the idea that electrical signals can represent data, such as numbers, words, pictures and music. 1980s was the beginning of the digital revolution, but engineers built the first digital computers during world war ii for breaking codes and calculating missile trajectories. 1950s, computers were marketed for business applications, such as payroll and inventory management. Centralized computing occurs when a main computer holds all of the data and performs all of the processing. A terminal is an input and output device that depends on a centralized (cid:498)host(cid:499) computer for processing and data storage. Computers were used in order to cut costs and manage mountains of data.
