Babbage invented a mechanical computer in the mid-nineteenth century. Electronic computers wer invenbted by a chap called Turing.
Digital circuits are the most common physical representation of Boolean algebra and are the basis of all digital computers. Computer's industrial processes are constructed of digital circuits.
The first electronic computer was called the ENIAC (Electronic Numerical Integrator and Computer).
John Mauchly, a mechanical engineer, co-invented with John Presper Eckert, the first general-purpose electronic digital computer, called the ENIAC. Later, the duo invented the first digital electronic computer available for sale to the general public, called the UNIVAC.
A gadget is a mechanical or electronic device with a practical use but often thought of as a novelty. It is a relative concept. For someone familiar with the latest tech trends, a gadget may simply be a device or equipment. For someone not up to date with current technologies, a gadget may bring an element of surprise and amusement.
According to "The Handy History Answer Book" by Rebecca Nelson the first Personal Computer was called Apple I. The first electronic digital computer was the Mark I . And the first mechanical computing machine was called the "analytical engine" though it was never completed.

The definition of an electronic computer is a machine for performing calculations automatically. They are sometimes called processor and are designed to perform operations and accept data.

It is considered a machine because of the multiple occurrences of independent thinking and learning supplied by the CPU and or the multifunctinal uses of said equation.A2It could be argued, the other way around. A computer is a Device rather than a Machine.A machine implies mechanical devices that move, like levers and gear mechanisms. A computer has no moving parts in itself, discounting the hard drive.A device, is a generic term for something that can be used.
