Definition - What does Analytical Engine mean?
Analytical engine most often refers to a computing machine engineered by Charles Babbage in the early 1800s. It is considered an early and very important step toward modern computer design. This term can also be used to refer to any comprehensive internal system for analytics.
Techopedia explains Analytical Engine
Although the Babbage Analytical Engine was never physically completed, this early computer would have necessitated quite a lot of physical metal construction and a large footprint of dozens of cubic feet in terms of its overall size. Even so, it was an important precursor to early mainframe computers. More advanced mainframe units still had a lot of analog assemblies and extremely large physical footprints compared to today’s digital computers, which accomplish so much more by means of electrical impulse. One other interesting fact about the Analytical Engine is its resident memory, which is estimated to have been, according to design, about 16.5 kB.
