COMPUTER FUNDAMENTALS

Detailed explanation-1: -The mill was the calculating unit, analogous to the central processing unit (CPU) in a modern computer; the store was where data were held prior to processing, exactly analogous to memory and storage in today’s computers; and the reader and printer were the input and output devices.

Detailed explanation-2: -Think of a room-sized machine with 7 meters of length and 3 meters of height just to perform mathematical calculations, but it’s 19th century (History of Analytical engine). So this thing was divided into 5 units – called arithmetic logic unit (ALU), basic flow control, punch cards, and memory.

Detailed explanation-3: -The central processing unit, which Babbage called the Mill, would be fifteen feet (4.5m) tall; the memory, or Store, holding a hundred 50-digit numbers would be twenty feet (6m) long (Babbage even considered machines with ten times that capacity); and other components included a printer, card punch, and graph plotter.

Detailed explanation-4: -During first generation of computers analytical engine were introduced. These first generation of computers use counter wheels as memory unit to store data. analytical engine was invented by Charles Babbage in 1833. It was first mechanical computer.
