Computers are built the same way any other electronic device is built, at the time it was built. As the methods of building electronic devices changed over time, the methods of building computers changed too.
Abacus was the first calculating device invented by the Chinese.
The counting device invented after the abacus is the calculating machine, with notable examples including Blaise Pascal's Pascaline in the 17th century and Gottfried Wilhelm Leibniz's stepped reckoner. These early mechanical devices were designed to perform arithmetic operations automatically, significantly advancing computational capabilities compared to manual counting methods like the abacus. The development of these machines laid the groundwork for modern calculators and computers.
No. The earliest known device using computer technology was the Hewlett-Packard 200A Audio Oscillatorio Oscillator, developed in 1939. There were calculator machines...

In China in 1960
the ABACUS. it is also known as the 1st calculating device created by the Chinese. it is also known as the 1st computer.
Modern days Computers are more developed form of Calculators. Earlier Calculators were devised for fast Mathematical Calculations.Calculators are devices designed to perform Simple & Scientific calculations whereas Computer (Computing Device) are designed to perform variety of Tasks with high speeds.
A complex machine is a mechanical device that consists of multiple simple machines working together to perform a more complex task. Examples include cars, computers, and robots.
They were big.

A simple machine is a type of machine that changes forces in some way, by amplifying them, and/or changing their direction. The lever, the pulley, the wheel and axle are all simple machines. But there are complex machines as well, which do far more things. Our computers are also machines.
