What are the Other Computing Machines than Computer?
The Digital Machine built at the Iowa State University from 1937 to 1942 is thought to be the first electronic, digital device to be made. It was known as Atanasoff-Berry Computer abbreviated as ABC. Atanasoff-Berry Computer was built by John V. Atanasoff in conjunction with Clifford Berry. The ABC made use of vacuum tubes to do digital computations involving Boolean logic and binary math; however, this device didn’t have a processing unit.
In 1943, J. Presper Eckert and John Mauchly initiated the ENIAC project at the University of Pennsylvania. ENIAC denotes Electronic Numerical Integrator and Computer and it took about 3 years to complete the machine. This was the first digital device that a person could program. The ENIAC was pretty massive and occupied a space of 1800 square feet. This computing machine had 18,000 vacuum tubes along with numerous capacitors, resistors, relays, and other components. The machine weighted almost 50 tons.

When you examine these computing devices, you find that they advanced in technology year after year, and the world’s first computer could be seen as the ENIAC. So, J. Presper Eckert and his counterpart John Mauchly may be said to be the people who built the first truly computing device despite its large size and weight. But the U.S. District Judge Earl R. Larson striped out this credit for J. Presper Eckert and John Mauchly in court by ruling that the concept utilized by J. Presper Eckert and his colleague was picked from John V. Atanasoff computing concept. So, ENIAC lost the patent right for their work.
ENIAC had the features of programmability and electronic speed that are key elements of a computer as we know it today. Although the Atanasoff–Berry Computer (ABC) and ENIAC used vacuum tubes or thermionic valves, the registers for ENIAC performed decimal arithmetic instead of binary arithmetic.
