Full Answer

Modern computers can be very small, and they appear in a variety of modern products. Small computers can be found in cellular phones, modern cameras and automobiles, where their incredibly fast mathematical abilities help make the lives of humans easier.

Primitive computers have been around for thousands of years, although they look nothing like modern computers. Completely bereft of moving parts, the first calculating devices were called counting boards. These boards featured grooved lines and beads that could be placed in the grooves. Such calculators were helpful for keeping track of large numbers; but soon, better tools, such as the abacus, were invented.

True calculating devices were invented in the early 19th century; but while these elaborate devices were more helpful than counting boards and similar tools, they were very expensive to construct.
